Avicopter (Chinese Aviation Company) exhibited its Feihong vertical takeoff-and-landing airplane, a technology demonstrator that is in flight testing. A lift fan is em bedded in the middle of the airframe of the aircraft, driven by a piston engine.
Flight testing revealed only straightforward problems at first, say officials, but the program is now working with advanced issue, such as trying to find the optimum method of achieving maximum altitude: with wing lift only, or with the aid of the fan. The Feihong is also a project of Avicopter’s Changhe Aircraft at Jingdezhen. The aircraft, not a model, was displayed at Tianjin.Note to Commenters: If you are reporting a sighting, be sure to include the location (city, state, country), date and time of your sighting.
