The Pivotal BlackFly is an American electric-powered VTOL personal air vehicle designed by Canadian engineer Marcus Leng and formerly produced by Opener, now Pivotal. It was publicly revealed in 2018, after nine years of development. The aircraft is supplied to customers complete and ready-to-fly.
The aircraft was substantially damaged. A review of the recorded data revealed that vibration occurred and briefly exceeded the jerk logic threshold used to detect contacts to the ground (in addition to squat switches). The aircraft entered the ground mode, subsequently commanding the motors to shutdown. [7]
In 2021, Urban eVTOL announced the Leo, a 3-seat, 250 mph (400 km/h), 300 mi (480 km) vehicle. It hosts 16 40-cm diameter, 10-kw ducted fans for vertical lift, and 6 28 cm diameter, turbine-bladed rear engines for horizontal thrust. The wing is a double box-wing design.

The tests require engine manufacturers to carry out at least two tests of the engine, to make sure that the engine can survive a compressor or fan blade breaking off within the engine and a turbine blade breaking off within the engine, without fragments being thrown through the outside enclosure of the engine, creating a contained engine failure.
Rotax is one of the world's principal suppliers of aircraft engines for ultralight aircraft, light aircraft and unmanned aerial vehicles. [2] Between 1985 and 1995, 60,000 Rotax engines were sold for aircraft propulsion. [2] In the light aircraft class, in 1998 Rotax outsold all other aero engine manufacturers combined. [4]
The MZ 202 was developed first as a 60 hp (45 kW) lightweight competitor to the liquid-cooled 64 hp (48 kW) Rotax 582.Later the MZ 201 was developed from the MZ 202 as a de-rated 45 hp (34 kW) version intended for motorgliders and single place ultralights that needed more power than the single-cylinder Zanzottera MZ 34.
After proving [citation needed] the engine reliability on the ground and in the air, the project was merged into an official company structure. ULPower Aero Engines was officially formed in March 2006 to concentrate on the further design and manufacture of engines where light weight, power and reliability are important to the client.
