Aircraft with double boat element

摘要

Using the known propulsion principles of catamarans, aircraft have on the outer ends of the possible V-form aerofoil(2) aerodynamic containers or airbags(3,4) which are filled with helium and extend in the direction of flight. These components are symmetrical to the aircraft's longitudinal axis and are conducive to stability and flight safety. The components are made of sheet aluminium, light metal sheet, plastic, or some other airtight material.
