Flight Characteristic Analysis of Fighter Aircrafts with Twin Jet Engines under the Asymmetric Thrust

Abstract:

Abstract:When one side jet engine of the twin jet engines in aircrafts fails, the aircrafts will sideslip relative to y-axis of aircrafts. The nose of the aircrafts will drop and the flight speed of the aircrafts will decrease. In order to maintain the balance of the aircrafts to ensure the safety of flight, the pilot has to carefully manipulate the aircrafts according to the actual situation and the control action. In this paper, dynamic characteristic of the aircrafts with twin jet engines under asymmetric thrust of aircrafts has been analyzed. Several manipulation methods of aircrafts with both the sideslip and bank were discussed to guarantee flight safety of aircrafts with asymmetric thrust. The control measurements to keep the balances of aircrafts were given to manipulate the aircrafts. In this situation, aircrafts will turn back as soon as possible and land at the nearest airport.
