VFW VC-400

During the 1960s, a number of VTOL programs were carried out by the West Germany aerospace industry. One of the most interesting was the VFW VC-400, which proposed two tilt-wing installations for VTOL flight.

Both tilt wings were located high on the fuselage, with the front wing positioned directly behind the cockpit. The rear wing was placed in front of the tail assembly. Turboprop engines were located on each wingtip - a most-interesting concept to be sure.

Trying to research the history of this project, as well as those of the American X-100 and X-19 projects which also used radial-lift propellers (Henry Borst, one of my favorite experts, was involved in those). I can be reached at if you can provide information.

Who is knowing Hans-Heinrich Rolai who has a photo of a tilt-wing model with two main rotors and two propeller units on a tiltable wing.

Wouldn't the rear props' efficiency be adversely affected by being directly in line with the front props in horizontal flight?

There are other solutions that can do so, as long as we are talking about designs that have never flown or proven themselves in the real world.

Heck, I have three that carry twice the payload right here:

From 1966 until 1969 I was section head avionics with VFW. The VC 400 then was the main effort area. It has to be emphasized, that as opposed to rotors the like on Osprey the high load propellers made the VC 400 much faster - 390 kts - while not carrying dead weight in the propulsion system. The power required for VTO is the same as the power required for cruise. There is no other solution, which can do so.

Do you have any comments ?
