Configurational automatic flight control closed-loop test system

Abstract

The invention discloses a configurational automatic flight control closed-loop test system and belongs to the technical field of aircraft testing. The configurational automatic flight control closed-loop test system includes a teletype control system, a high lifting force system, an automatic flight control system, an automatic flight control tester, a telex control tester and a flight simulator.The high lifting force system controls a slat movement mechanism to move and collects slat deflection signals; the high lifting force system sends the slat deflection signals to the teletype control system; slat signals are transmitted to the automatic flight control tester through the teletype control system and sent to the flight simulator through a reflection memory net; the flight simulator receives the slat signals and aircraft movement signals and then resolves flight attitude signals, and the flight attitude signals are transmitted to the telex control tester and the automatic flight control tester, to implement aircraft closed-loop control. Unnecessary testing devices are reduced, reliable stable high-precision configurational signals are provided for the flight simulator, and long-term high-strength test requirements are met.

Description

technical field [0001] The invention belongs to the technical field of aircraft testing, and in particular relates to an automatic flight control closed-loop test system with configuration. Background technique [0002] In the current aircraft test environment, the configuration signal (flap and slat signal) is generally provided by the aircraft test system. The test system collects the signal through the test sensor, and sends it to the flight simulator after passing through the isolation amplifier. [0003] This method requires very high sensor installation requirements, fixture design, and environmental requirements. At the same time, the test equipment must be calibrated regularly. The aircraft control system needs to do a lot of tests in the development stage. The test period is long and the test density is high. This requires the test equipment to provide reliable work. The current situation shows that the test system can meet the requirements in the short term, but it...

Problems solved by technology

The aircraft control system needs to do a lot of tests in the development stage. The test period is long and the test density is high. This requires the test equipment to provide reliable work. The current situation shows that the test system can meet the requirements in the short term, but it cannot meet the test intensity in the long term. Aircraft flaps and slat signals are a necessary part of aircraft configuration design, so reliable, stable, accurate and long-term requirements are put forward for configuration signals in the test
