Wingless Vertical Take-off Aircraft / Dornier

Experimental study of the Aerodyne principle on behalf of the Federal German Ministry of Defence. According
to A.M. Lippisch, an Aerodyne is a wingless, unmanned vertical take-off aircraft. Testing of the Aerodyne E1 experimental unit was completed successfully on 30 November 1972. An Aerodyne combines lift and propulsion generation in a single structural unit, the inner flow channel, which is an annular wing with a fan. Without any change in its configuration, the Aerodyne is capable of stable flight through the full range from hover to
maximum speed.

Air is deflected by flaps at the end of the flow channel in order to supply the necessary lift and thrust. The performance in Flight is between that of an helicopter and that of a conventionl aircraft. Aerodyne will reach
good flying performance both in fast flight and in hover. In forward flight, pitch and yaw control is by means of
the control surfaces of a conventional tail unit at the end of the tail boom.

Application: unmanned reconnaissance flight - land and ship-based. The craft is remotely radio-controlled. First
flight: 18 september 1972.



The Lippisch Aerodyne

By Dr. Alexander Martin Lippisch (1894 - 1976)



To generate lift and propulsion the Lippisch Aerodyne would utilize two co-axial propellers, diverting the
slipstream downwards to achieve VTOL. Control would be achieved by deflecting part of the slipstream emerging
from the tail boom and use of the propeller flaps. Despite provision for a cockpit, only unmanned craft were built
and tested at Collins, operated by electric cables. Collins did mange to construct a full scale mock-up of the
Aerodyne and Lippisch patented the concept in 1959.

In 1967, Dornier picked up the Lippisch Aerodyne concept with the intent on further development. Dr. Lippisch
was brought on as chief consultant on the craft.
