Abstract
Flap pressure shape biasing is disclosed. A disclosed example apparatus includes a flight monitor to determine a movement parameter of an aircraft, the movement parameter corresponding to at least one of a Mach number of the aircraft, an airspeed of the aircraft, or a vertical acceleration of the aircraft, and a spoiler controller to adjust a position of a spoiler of the aircraft to reduce pressure on a flap based on the movement parameter by moving a pressure transition away from the flap.
Claims22
An apparatus for pressure shape biasing of an aircraft, the apparatus comprising:
- a flight monitor to determine a movement parameter of the aircraft, the movement parameter corresponding to at least one of a Mach number of the aircraft, an airspeed of the aircraft, or a vertical acceleration of the aircraft;
- a load calculator to calculate a load of a flap based on the movement parameter;
- a pressure correlator to compare the calculated load to a load threshold;
- and
- a spoiler controller to adjust, based on the comparison, a position of a spoiler of the aircraft to reduce pressure on the flap by displacing a pressure transition away from the flap.
A method to bias a pressure shape corresponding to an aircraft, the method comprising:
- determining, by executing instructions with at least one processor, a movement parameter, the movement parameter corresponding to at least one of a Mach number of the aircraft, an airspeed of the aircraft, or a vertical acceleration of the aircraft;
- calculating, by executing instructions with the at least one processor, a load of a flap based on the movement parameter,
- comparing, by executing instructions with the at least one processor, the calculated load to a load threshold;
- and
- determining, by executing instructions with the at least one processor, an adjustment of a position of a spoiler of the aircraft based on the comparison to move a pressure transition away from the flap.
A non-transitory computer readable medium including computer executable instructions that, when executed, cause a processor to at least:
- determine a movement parameter, the movement parameter corresponding to at least one of a Mach number of an aircraft, an airspeed of the aircraft, or a vertical acceleration of the aircraft;
- calculate a load of a flap based on the movement parameter,
- compare the calculated load to a load threshold;
- and
- determine, based on the comparison, an adjustment of a position of a spoiler of the aircraft to move a pressure transition away from the flap.
