Embodiment Construction

[0053] Multi-stage control technology is applied to manipulate split ailerons of aircraft with flexible wings to increase the aircraft's reaction speed. Optionally, the speed of the aircraft is determined in response to receiving a command to maneuver the aircraft. Then, based on the speed of the aircraft, the parts of the split aileron are acted differently. Below a first speed threshold, the inboard and outboard portions of the aileron are moved substantially together. Between the first speed threshold and a second, greater speed threshold, the outboard portion of the aileron is locked and the inboard portion of the aileron is moved independently of the outboard portion. Above a second speed threshold, the inner portion is moved substantially oppositely to the outer portion.

[0054] refer to figure 1 , a typical modern aircraft 10 has a fuselage 11 , a pair of wings 14 and a tail 16 equipped with a cockpit 12 and one or more flight components 18 . Aircraft 10 may be any...

Abstract

The present invention provides methods and system for controlling the operation of an aircraft aileron which comprises an inboard portion and an outboard portion. A velocity of the aircraft is determined. Then, based on the velocity of the aircraft, the aileron is caused to move in certain ways. When the velocity is below a first velocity threshold, the inboard aileron portion and the outboard aileron portion are caused to move substantially in unison. When the velocity is between the first velocity threshold and a second, greater, velocity threshold, the outboard portion of the aileron is caused to lock and the inboard portion of the aileron is caused to move independently from the outboard portion. When the velocity is above the second velocity threshold, the inboard portion is caused tomove substantially opposite from the outboard portion.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 356,767, filed June 30, 2016, the contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates generally to fly-by-wire aircraft and, more particularly, to the control of split ailerons of fly-by-wire aircraft. Background technique [0004] While traditional aircraft are mostly mechanical systems, many modern aircraft use so-called "fly-by-wire" technology. In short, conventional aircraft use mechanical linkages to translate operator commands, such as pressing a pedal or tilting a flight stick, to move a flight part, such as raising or lowering an aileron. In contrast, a fly-by-wire aircraft converts commands, for example from an operator, into electrical signals, whether analog or digital. The fly-by-wire controller processes the received commands to generate control signals, which are...
