RIGHTS TO INVENTIONS MADE UNDER FEDERALLY-SPONSORED RESEARCH AND DEVELOPMENT
None of the work on this invention was performed under any Federally-Sponsored or State-Sponsored research and development. Gabriel used his own resources on every phase of his project.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is in the field of aircraft safety in flight, wherein even if the pilot were to make an error, the system will attempt to make corrections to avoid and prevent the aircraft from crashing. This system could be applied both to a fixed or a rotary wing aircraft. This disclosure with illustrations describes how the system functions to prevent an aircraft from going out of control and crashing, using rate of turn sensors, high pressure air tanks and solenoid-operated valves.
2. Description of Prior Art
The inventor is aware only of his own U.S. patent applications. His Ser. No. 09/366,263, filed Aug. 02, 1999, includes drawings of a fixed wing and a rotary wing aircraft, utilizing compressed air tanks, solenoid-operated air valves and micro switches sensitive to wind gusts. A drawing also is shown of a belly of a fixed wing aircraft with tanks and air valves for providing buoyancy to the aircraft when its speed of descent becomes too rapid. A relay closes the circuit for the solenoid to operate and open the valve inlet ports for high pressure air from the tanks to pass through and blast out at their outlet ports, to provide buoyancy for the air craft.
SUMMARY OF THE INVENTION
This is a novel technique for helping to prevent a lightweight aircraft from crashing should the aircraft experience engine or mechanical control problems. Air valves are judiciously positioned on the belly of the aircraft and their controls are zoned to blast out high pressure air at selected air valve outlet ports, to provide buoyancy and/or to prevent the aircraft from rolling and pitching along their axes in excess of a predetermined value in degrees. A rate of turn sensor is provided for each of the following: left side and right side roll, and pitch angle. An altimeter, sensitive to the rate of the aircraft's descent, is provided with an output voltage to operate a relay to close the circuits for the solenoid-operated air-valves, providing aircraft buoyancy, to slow down the aircraft's rate of descent. A law in physics states that for each action there is a reaction. This is essentially the principle that enables the aircraft to experience buoyancy when the air valves are blasting out high pressure air in the desired direction.
