Fuel-less gravity powered flight
The new hybrid gravity-powered aircraftis formed by merging the capabilities of the following devices into a single new aircraft apparatus: (1) an aircraft capable of aerostatic (lighter-than-air) lift to gain altitude; and, (2) a glider aircraft capable of aerodynamic lift, having a high glide ratio to accomplish long range gliding; and, (3) an innovative new extremely low drag vertical axis wind turbine that is capable of harnessing the force of the wind to generate power as the aircraft glides upward via positive buoyancy and glides downward via gravity acceleration.Robert D. Hunt, the Chairman of Hunt Aviation, has filed for international patent protection for an innovative new phase change hybrid airship design powered by the thermal energy in the air. The energy to power gliding flight is obtained from the atmosphere itself. An efficient power cycle is created using the natural temperature difference from a low altitude to a higher altitude. Heat energy is taken from ambient temperature air at a lower altitude to power the GravityPlane and heat is rejected to colder air at high altitude to complete the power cycle. This Atmospheric power cycle can be repeated indefinitely to allow the craft to stay aloft virtually forever.
