Highlights
Evangelizing agentic workflows to aerospace engineers and seeing them have aha moments is a sweet, sweet feeling. Especially knowing that it pulls forward the future we are building
Saw a Kitty Hawk Flyer in person with two of the former engineering team. They had done 25,000 test flight flights and built over 100 aircraft by the end of the program. Some thoughts:
Overlapping rotors expanded the wing-in-ground effect. At ~3 meters altitude they were drawing about 80% of the power they would need out of ground effect. That’s too large to be explained by wing-in-ground-effect alone. The interpretation is that the overlapping disks let the system behave more like one larger rotor, effectively increasing "effective disk diameter" and reducing hover power.
It could be materially lighter without landing on hard surfaces. Being designed predominantly for operation on grass, water, and inflatable platforms relaxed the landing loads and structural requirements. This allowed them to meet the weight restrictions for ultralights without a float allowance, despite having pontoons for water landings.
Exceptional flight time. Low disc loading helped it could fly in forward flight for 30 minutes at Vbe of ~45 mph. That’s despite the Flyer having low energy dense but high specific power LiPo cells, which makes that figure even more impressive.
Blade failure was treated as a real design case. It used multiple layers of Kevlar in some areas of the fuselage shell for pilot protection from blade separation. The assumption was that prop failure may be unlikely to happen, but when it does, blades must be managed safely.
Manufacturing and operations were already thinking at consumer scale. They were producing roughly one Flyer every three days and planning to train over 10,000 users the following year right before COVID hit before the program was scrapped.
Test ops were automated and parallelized. When they ramped up the test rate, they had 12 autonomous, waypoint-driven Flyers flying at once at their test field with test flight engineers monitoring.
They were a little too far ahead of their time.
