3. Safety
Safety is the single most important aspect of this program. The procedures proposed and
their effective management will create a safety culture within the program that will safeguard all
personnel involved.

3.1 Safety Plan

All materials listed in OSHA Hazardous Materials list will be handled in accordance with
the standards given by the Occupational Safety and Health Administration (OSHA). Along with
following all the standards outlined, any member handling hazardous materials will wear the
proper personal protective equipment. Before the beginning of the construction phase, all team
members will receive a safety training briefing about the proper use of the facilities where
construction will take place. The purpose of this meeting will be to inform team members of
possible safety issues and how to address dangerous situations when they occur. The designated
Safety Officer for the Oakton High School Rocketry team throughout the 2019-2020 competition
is Landon W. The Safety Officer’s duty is to inform team members of safety issues and
regulations and then ensure team members follow these regulations. Attached to this proposal
(see Appendix A) is a risk assessment identifying risks to/from personal, project completion,
environment, and part failure.
3.1.1.
Throughout all launches, the Safety Officer and team members will insure that the NAR
High Power Safety Code is followed. The NAR/TRA mentor, Joe Woodford, will purchase the
motors. Only commercial motors will be used. The motors will be stored properly to prevent
damage. If motors are damaged, they will not be used in the launch of the rocket. The motors
will be disposed of properly. The one controlled substance that will be used in the rocket is black
powder. The team’s black powder will be acquired through commercial suppliers by utilizing our
NAR member’s Low Explosives User’s Permit (LEUP). Following its purchase, the black
powder will be stored in a separate container that prevents any cross contamination or accidental
ignition. Any black powder that becomes contaminated before launch will not be used. The

7
launches will take place at Great Meadow, which is under the supervision of the Northern
Virginia Association of Rocketry (NOVAAR).
3.1.2.
At the safety training briefing before the start of construction, all team members will be
informed on all possible hazards that may occur in any aspects of the project. Team members
will also be taught ways to avoid accidents by the Safety Officer. Before each launch, both
subscale and full scale, a separate pre-launch briefing will occur. The briefing will remind team
members of possible dangerous during the launch, review events that could cause launch
cancellation, and teach what to do in the case of certain launch failures that may occur.
3.1.3.
In all plans, procedures, and other working documents, hazards and the use of Personal
Protective Equipment will be signified by the following symbols. The purpose of these symbols
is to call attention and ensure the team will follow the guidance given.

 For a potential safety hazard a stop sign will be shown. Underneath the stop sign will be
the statement “POTENTIAL SAFETY HAZARD” in large, red text. Example of the symbol
below:

 To signify the use of Personal Protective Equipment is required a pair of rubber gloves will
be shown. Underneath the rubber gloves will be the statement “USE PERSONAL
PROTECTIVE EQUIPMENT” in large, orange text. Example of the symbol below:

8
3.1.4

Mr. Joe Woodford has agreed to mentor the team and accompany the team to all launches
including Huntsville. He is certified level 2 with the NAR and has previously served as mentor
for five Student Launch teams. He will manage all hazardous restricted material and participate
in all pre-launch safety briefs. All team members will be briefed on federal, state, and local laws
regarding unmanned rocket launches and motor handling. These briefings will be administered
by the Safety Officer. Specific laws that will be covered in the briefing are: Federal Aviation
Regulations 14 CFR, Subchapter F, Part 101, Subpart C; Amateur Rockets, Code of Federal
Regulation 27 Part 55: Commerce in Explosives; NFPA 1127 “Code for High Power Rocket
Motors.”; and the NAR High Power Safety Code.

3.1.5

The NAR/TRA mentor, Joe Woodford, will purchase the motors. Only commercial
motors will be used. The motors will be stored properly to prevent damage. If motors are
damaged, they will not be used in the launch of the rocket. The motors will be disposed of
properly. The one controlled substance that will be used in the rocket is black powder. The
team’s black powder will be acquired through commercial suppliers by utilizing our NAR
member’s Low Explosives User’s Permit (LEUP). Following its purchase, the black powder will
be stored in a separate container that prevents any cross contamination or accidental ignition.
Any black powder that becomes contaminated before launch will not be used.

4. Technical Design
The proposed design for this project is a standard single stage rocket. It will support a
fully redundant recovery system, program payload and tracking system.

4. a. Vehicle Dimensions, Material Selection, and Construction Methods

The proposed rocket is a 4” dual deployment one-stage rocket with 3 sections. The rocket
will be made from 4in diameter blue tube and each section will be connected by 4in shoulders in
accordance with 2.5.1. The nose cone is an ogive LOC precision 3.9in nose cone that is made of
polystyrene, hollow and 12.8in long. The nose cone will use 2/256 in. shear pins to connect it to
the forward parachute compartment. The shear pins are meant to prevent the nose cone from
separating prematurely. There will be a bulkhead with an eyebolt attached to the base of the nose
cone. The body tube for the forward parachute compartment is 31in long, which will include 17
in. for the main chute that is 84in in diameter and 20 ft of ¼ tubular Kevlar shock cord with 3/16
quick links on each side. The forward parachute compartment will be bolted to the electronics
bay with a 4 in. coupler. The electronics bay is 16in. long and contains a 2-sided sled resting on
all-threads. The redundant dual-deployment recovery system and payload electronics will be
mounted on the sleds. On both sides of the electronics bay, there is a bulkhead with an eyebolt.
The booster section will use 6 shear pins to be connected to the electronics bay until ejection at
apogee. The booster’s body tube is 38 in. which will include 16.75 in. for a 18 in. drogue chute,
20 ft. of the same Kevlar shock cord, a parachute protector, and a 54mm motor mount. The
motor mount will use a 13.5 in. long motor tube, which is held in place with 3 centering rings
with an Aeropark 54 mm retainer on the end. The frontmost centering ring will have a U-bolt.

15
The initial guidance will be provided by 1010 rail buttons. The rocket will use 3, mounted
through the wall, laser cut trapezoidal fins. They have a root chord of 4.625in with a tip chord of
2.625in and a semi-span of 3.5in.The tab length is equal to the root chord, with a tab depth of
0.87 inches. The thrust to on pad weight of the rocket, at 13, exceeds the minimum ratio of 5:1
and is therefore stable enough to take off safely.
A sub-scale model with a similar configuration to the proposed full-sized rocket will be
made using 2.56in body tubes with parts to scale. It will be used as a test bed for dual
deployment and as an introduction to dual deployment and safety procedures related to it for
members who have no prior experience in dual deployment. The sub-scale model will also be
used to verify preflight checklists and procedures.

4. b. Projected Altitude and Calculations

The target altitude is 4000 feet. It will take approximately 15.8 seconds to reach apogee.
The rocket's velocity at rail exit is at an estimated 77 feet per second. The static margin of the
rocket is 2.19. The estimated total mass is 6960 grams. The center of gravity is 49.5 in. away
from the nose cone, while the center of pressure 58.3 in. away from the nose cone. The
simulation was done in RockSim.

4. c. Planned Recovery System Design

The recovery system will consist of two independent Dual Deployment systems using the
Perfectflite Stratologger CF. Each system will have their own battery and charge well. There will
be primary and backup dual deployment systems, with the primary ejecting the main chute at
700ft and drogue at apogee, and the backup ejecting the main chute at 500ft and the drogue at 1s
after apogee. The Dual Deployment systems will be placed parallel on opposite sides of a 2-sided
sled in between two bulkheads. There will be a bulkhead in between the transmitters and the
flight computers. An eyebolt and 2 charge wells for each system will be mounted on the front
and aft electronics bay bulkheads. The main parachute charge wells will contain 1.63g of black

16
powder while the drogue chute charge wells will contain 1.54g of black powder. The recovery
system will be operated via 2 switches, one for each dual deployment system, which will be
accessed on the outside of the rocket.
The proposed parachutes will permit the rocket to land on the field with a speed of 22ft/s
with a flight time of under 90 seconds, giving the heaviest section 71.94 ft-lbf of kinetic energy
upon landing.

4. d. Projected Motor Design and Brand

4. e. Detailed description of the team’s projected payload


4.e.1. Requirements

The payload will use electronic sensors for examining the effects of the sensor type on
accuracy of measured altitude. A lightweight, fast and power efficient microcontroller such as
the STM32 or Arduino will be used to coordinate the gathering of data. An altimeter,
accelerometer, and a GPS will be placed in the payload area and will calculate in real-time the
rocket’s acceleration, velocity, and position using relevant integration or derivation techniques.
For the accelerometer, different integral approximation methods such as the rectangular Riemann
sum, trapezoidal sum, and a custom prediction-based sum based on the known force curve of the
engine will be tested and compared. Additionally, we will examine the effects of the presence of
static ports in the body tube on altimeter accuracy. To accomplish this, we will be using two of
the same air pressure-based altimeters in two different, isolated sections of the payload bay. We
hypothesize that the altimeter with access to static ports will be the most accurate, however the
altimeter in the body tube will never exceed 10% error of the static ports’ altimeter. For the
different integration techniques, our hypothesis is that custom force graph integral approximation
method will be the most accurate followed the trapezoidal method then last by the rectangular
method.
4.e.2 Design

This telemetry data will be downlinked using a radio antenna to a ground station which
will graph the data in real-time and store it for later review. With the help of a gyroscope within

18
the payload and the position and velocity data from the aforementioned sensors, the ground
station will render the rocket’s current path and projected path, in real-time, in 3D. The ground
station will be written in C++ using GLFW and ImGui to display the graphics. The program for
the payload will also be written in C++ using Visual Studio, Premake and the relevant
microcontroller libraries for interacting with the sensors.
4.e.3 Deployment

Both pieces of software will be version controlled, allowing to keep track of the changes
made and minimize errors. We will keep a board of all tasks that are pending, complete, and
upcoming along with their priority to keep the project on track. The ground station will be
designed and deployed with cross platform functionality in mind (meaning it will work on
Windows, Mac, and Linux). Two weeks before a launch, the ground station will be compiled and
then rigorously tested. The club’s laptop along with 2 backup laptops will download the
software. On launch day we will be able to swap laptops in the case of a failure by plugging the
radio receiver into another laptop and running the software. The payload portion of the program
will be flashed onto the microcontroller and all sensors and functions will be tested before
integrating the payload with the rest of the rocket on launch day.
4.f. General, Vehicle, Recovery, Payload, and Safety Requirements

Vehicle:
2.1 & 2.16: According to RockSim and OpenRocket simulations, the rocket achieves
about 4400ft at apogee and reaches 66ft/s upon leaving the launch rail.
2.3 & 2.4: The rocket will use Stratologger CF altimeters which will be used in our dual
deployment system which allows it to be reusable while recording the altitude at apogee.
2.5: The design utilizes 3 independent sections, the nose cone, payload body tube, and
motor body tube. Coupler shoulders are at least 1 body diameter in length (4in) and the nose
cone shoulder is at least ½ body diameter in length (2in).
2.11 & 2.12: The rocket will use a single commercially available AeroTech J401F.
2.22: The rocket design does not include any forward canards, it also uses a single back
facing motor that is not capable of reaching Mach 1 on our rocket.
Recovery:

19
3.1: The launch vehicle will use a dual deployment system that does not utilize any motor
ejection system that will deploy the main chute at 700ft and the drogue at apogee with less than 2
seconds delay.
3.3: Each independent section of the rocket will have less than 75ft-lbs upon landing at
20ft/s
3.4: The dual deployment system will include a main and backup Stratologger CF. which
will be powered by a 9V battery, that will deploy the main at 500ft in case the main altimeter
malfunctions.
3.6 & 3.7: The system will have an external key switch that cannot be triggered mid
launch which will turn the recovery system on and off.
3.8 & 3.13: The recovery electronics are separated from payload electronics via bulkhead
and will include protection such as an RF shield.
3.10, 3.11, & 3.12: The main parachute will be deployed at 700 feet (ft), resulting in a
horizontal displacement less than 2500ft and a flight time of under 90 seconds given 20 miles per
hour (mph) of wind according to RockSim and OpenRocket simulations.
Payload:
2.7: The payload will utilize a 2500 milliamp hour li-po battery which combined with the
estimated power consumption of 1200mA will yield a battery life of more than two
hours. Additionally, a special low power mode for the microcontroller will be used while
the vehicle awaits launch.
2.18.2.2: The payload will be flown at least once in a payload demonstration flight.
2.21: The (lipo) battery will be placed inside the protected payload section and colored
with bright orange tape.
4.g. Major Technical Challenges and Solutions

Dual deployment altimeter may malfunction and not ignite drogue/main ejection charges,
so there will be two independent dual deployment altimeters installed in order to reduce the
chance of altimeter failure.
Rocket may not reach estimated apogee due to the extra weight not calculated during
mass approximations. During the design phase, the total mass will be overestimated so if the

20
rocket was heavier than the calculations, then the overestimation will allow us to adjust ballasts
to the designed mass.
Isolation of two barometric altimeters may become a problem. We plan to use a rubber
gasket or a bead of plastic to prevent air from the holes in one compartment from changing the
pressure in lower compartments.
Calibration of barometric altimeters (and correlation to the actual height) may fail. This is
unlikely, but if it happens, we will connect proper altimeter packages directly to the
microcontroller.

6.2 Budget

6.3 Funding Plan

We plan to get funding for our project through sponsorships from local companies and
fundraising. We are in the process of contacting companies and arranging to give an overview of
our mission through presentations. We plan to fundraise money through bake sales, doing

24
services in neighborhoods such as raking leaves, shoveling snow, washing cars, walking pets,
and tutoring.

6.4 Sustainability

Oakton’s Rocketry Club is committed to sustaining its programs for future students with
a focus on giving them opportunities to take part in the Club’s activities and gain related
technical skills in the engineering field. A key part of ensuring that the Rocketry Club continues
its programs is the recruitment of potential team members. Our recruitment process has shown
success since recent years have seen the Club growing in membership. We will continue to
promote the Club through Oakton’s annual Cougar Kickoff, which allows the school’s activities
and clubs to advertise themselves to the student body. We will also continue to post flyers
throughout the school and the morning announcements to further reach potential members. This,
along with our interest meeting, will introduce the Club’s activities with the objective of igniting
a passion for rocketry and STEM.
Additionally, we will begin incorporating STEM Outreach events in our community to
extend our recruitment efforts through local elementary schools and public libraries. With these
events, we will organize STEM-related activities to introduce children and cultivate an interest
them for the STEM fields, who may not have had previous exposure. It is crucial for us to
recruit at our feeder elementary schools since those students will eventually attend Oakton High.
By sparking in them an interest in science and engineering, these students may eventually join
Oakton’s Rocketry Club and thus provide a sustained supply of future members who participate
in our TARC program and our SLI program.
We will continue to maintain our corporate sponsors through our media presence to
show our mission progress and visit our corporate sponsors to showcase our rocket. Our
Instagram and Facebook page will have regular updates of our meetings and developments of our
progress.
