PURPOSE: To permit an aircraft to travel as a car using two jet engines, to land and take off vertically, and to fly horizontally by providing a folding fin and an expansion type tail assembly.

CONSTITUTION: The main body 1 forms a fin crosssection and has a turboprop type jet engine 6 and a folding type main assembly 2 at the upper part. A tail assembly is mounted on an extension type tail rod 3. The lower part of the main body has a driving wheel 5 and a pulse jet engine 8. A jet engine 7 can change the nozzle direction for propelling and vertical landing and takeoff. An aircraft can be used as a vertical landing and takeoff aircraft car using these two jet engines.
