Power surge landing system
An aircraft landing system is disclosed. In various embodiments, an aircraft landing system as disclosed herein includes a processor that determines to start a final stage of descent for the aircraft. The processor determines a set of commands for actuators of the aircraft, based on the determination to start the final stage of descent, to flare the aircraft while wings of the aircraft are substantially in a forward flight position followed by transitioning to a vertical tilt position and completing the landing in substantially vertical flight. The commands are provided to the actuators of the aircraft.
1. An aircraft landing system, comprising:
a processor configured to:
determine to start a final stage of descent for the aircraft;
determine a set of commands for actuators of the aircraft, based on the determination to start the final stage of descent, to flare the aircraft while wings of the aircraft are substantially in a forward flight position followed by transitioning to a vertical tilt position and completing the landing in substantially vertical flight; and
provide the set of commands to the actuators.
2. The system of claim 1 , wherein the set of commands are determined based at least in part on a net loss of lift.
3. The system of claim 1 , wherein the processor automatically determines to start a final stage of descent for the aircraft in the event the aircraft is substantially close to ground.
4. The system of claim 1 , wherein the processor is configured to automatically determine to start an initial stage of descent for the aircraft.
5. The system of claim 4 , wherein the initial stage of descent for the aircraft comprises a low power stage and the final stage of descent for the aircraft comprises a high power stage.
6. The system of claim 4 , wherein the final stage of descent for the aircraft occurs in a shorter amount of time than the initial stage of descent.
7. The system of claim 4 , comprising an interface configured to receive sensor data, wherein a determination to start a stage of descent for the aircraft is based at least in part on the sensor data.
8. The system of claim 4 , wherein a determination to start a stage of descent for the aircraft is determined based at least in part on manual controls.
9. The system of claim 7 , wherein the sensor data is collected using radar, lidar, or a camera.
10. The system of claim 4 , wherein the initial stage of descent comprises diving.
11. The system of claim 4 , wherein the aircraft is in a cruise position in the initial stage of descent.
12. The system of claim 1 , wherein the aircraft comprises one or more wings that are able to tilt during flight.
13. The system of claim 1 , wherein the aircraft comprises two parallel tiltwings that each comprise two rotors positioned on leading edges of the tiltwings.
14. The system of claim 12 , wherein a leading edge of the one or more wings is shallowly angled upwards away from a nose of the aircraft in an initial stage of descent.
15. The system of claim 12 , wherein a leading edge of the one or more wings is fully tilted and perpendicular to a fuselage of the aircraft in the final stage of descent.
16. The system of claim 13 , wherein all rotors are parallel to a fuselage of the aircraft and are positioned over the fuselage of the aircraft in the final stage of descent.
17. The system of claim 13 , wherein all rotors are at maximum throttle in the final stage of descent.
18. The system of claim 1 , wherein throttle is set to zero in the event the aircraft touches ground.
19. A method for landing an aircraft, comprising:
determining to start a final stage of descent for the aircraft;
determining a set of commands for actuators of the aircraft, based on the determination to start the final stage of descent, to flare the aircraft while wings of the aircraft are substantially in a forward flight position followed by transitioning to a vertical tilt position and completing the landing in substantially vertical flight; and
providing the set of commands to the actuators.
20. A computer program product for landing an aircraft, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
determining to start a final stage of descent for the aircraft;
determining a set of commands for actuators of the aircraft, based on the determination to start the final stage of descent, to flare the aircraft while wings of the aircraft are substantially in a forward flight position followed by transitioning to a vertical tilt position and completing the landing in substantially vertical flight; and
providing the set of commands to the actuators.
