Abstract
Aircraft pitch control systems and methods are disclosed. An aircraft pitch control system (28) comprises a movable horizontal stabilizer (24) and an elevator (26) movably coupled to the horizontal stabilizer. The elevator is electronically geared to the horizontal stabilizer.
Claims23
An aircraft pitch control system comprising:
- a first actuator configured to actuate a movable stabilizer associated with a pitch of the aircraft;
- a second actuator configured to actuate an elevator movably coupled to the stabilizer;
- and
- one or more data processors operatively coupled to the first actuator and to the second actuator;
- and
- machine-readable memory storing instructions executable by the one or more data processors and configured to cause the one or more data processors to:
- using data representative of a commanded stabilizer actuation amount and data representative of a gearing relationship between the stabilizer and the elevator, determine a corresponding elevator actuation amount associated with the commanded stabilizer actuation amount;
- and
- generate an output for causing the first actuator to actuate the stabilizer according to the commanded stabilizer actuation amount and for causing the second actuator to actuate the elevator according to the corresponding elevator actuation amount.
6 more elements
A method for controlling the pitch of an aircraft using a movable stabilizer of the aircraft and an elevator movably coupled to the stabilizer, the method comprising:
- actuating the stabilizer;
- and
- actuating the elevator based on an electronic gearing relationship between the stabilizer and the elevator.
