there was a monumental breakthrough on Feb 10 as Boom Supersonic’s XB-1 aircraft accomplished the unprecedented in aviation history: supersonic flight without generating a sonic boom over the Mojave Desert

Boom Supersonic’s XB-1 has changed this narrative through its implementation of Mach cutoff technology. This innovative approach exploits atmospheric conditions to redirect shock waves upward rather than toward the ground. By carefully selecting specific flight altitudes and analyzing atmospheric data, the aircraft effectively minimizes the impact of these pressure waves.

The recent test flight’s success was meticulously documented using advanced Schlieren photography, which visually captured the aircraft’s shock wave patterns. These images provided concrete evidence of the technology’s effectiveness, showing how the waves dispersed without forming the concentrated pressure front that creates sonic booms.

Interesting how being impressed at the young age of 10, by the flight of the Wright brothers, led Roy Chadwick to a career with Avro, and to him designing the Avro Lancaster




Born at Marsh Hall Farm in 1893, Chadwick was the family's fifth generation of engineers. He studied night school at the Manchester Municipal College of Technology (1907-11) while also training as a draughtsman at the British Westinghouse Electrical Company, which he joined as a 14-year-old. 

As far as aviation was concerned, he was really in at the beginning, enthused by the new technology from the point when the Wright brothers took to the air in December 1903, Chadwick by then just a wide-eyed lad of 10.

At 18 yrs old, he began his association with Avro, he then worked on various designs in the lead-up to WW1 including the Avro 504, a Great War light bomber and trainer. King George VI learned to fly on one of these when he was Duke of York, while the very first QANTAS was an Avro 504K.

 When still only 22, Chadwick designed the Avro Pike twin-engine bomber (1915), the first bomber to have internal bomb stowage and a gun turret, and his rapid ascent continued, for in 1918 Chadwick had become Avro’s chief designer, coming up with the first true light aeroplane, the aptly-named Avro Baby. 

Two years later he added the world’s largest single-engine bomber. 

A variant of the Baby, the Antarctic Baby, was supplied for explorer Sir Ernest Shackleton’s final expedition to the Antarctic (1921).


However, it was as the designer of the Lancaster that Chadwick would be most remembered. In the late 1930s work had begun on a long-range bomber, the Avro Manchester, which was followed by the iconic Avro Lancaster, dubbed the best bomber of the war and the one used most often for night raids, capable of carrying 10 tons of bombs.

a couple nice AMXs, the bronze one is full race

 







the oil filter is on this mounting plate, with this interesting sticker on it


Fletcher Aviation was a sponsor of a Porsche in the 1954 Carrera Panamericana  https://en.wikipedia.org/wiki/Fletcher_Aviation


and Frank Fletcher, one of the 3 Fletcher Aviation brothers, designed executive desks, and had them built at Fletcher Aviation




that is one boring dash, very very flat
