Title:
AIRCRAFT STALL PROTECTION SYSTEM
Document Type and Number:
Japanese Patent JP2017047887
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an aircraft stall protection system that calculates two different maximum angles of attack and limits an aircraft angle of attack to the at least two different maximum angles of attack at different times.SOLUTION: An aircraft stall protection system and method include calculating a first angle of attack and a second angle of attack based on aircraft configuration and environmental conditions. The first angle of attack is greater than the second angle of attack. The system and method limit an actual aircraft angle of attack to the first angle of attack for a predetermined period of time and thereafter the system and method limit the actual aircraft angle of attack to the second angle of attack. The system and method allow an operator or pilot of an aircraft to extract maximum performance from the aircraft relating to a specific set of flight conditions, without the risk of stalling or the risk of remaining in a high drag state for a long period of time. This system and method are suitable for use together with a stall warning system.SELECTED DRAWING: Figure 1
