반응형 PHAK4 PHAK Chapter 6-18 Spoilers Spoilers Found on some fixed-wing aircraft, high drag devices called spoilers are deployed from the wings to spoil the smooth airflow, reducing lift and increasing drag. On gliders, spoilers are most often used to control rate of descent for accurate landings. On other aircraft, spoilers are often used for roll control, an advantage of which is the elimination of adverse yaw. To turn right, for .. 2021. 8. 18. PHAK Chapter 6-10 T-Tail T-Tail Since flight at a high AOA with a low airspeed and an aft CG position can be dangerous, many aircraft have systems to compensate for this situation. The systems range from control stops to elevator down springs. On transport category jets, stick pushers are commonly used. An elevator down spring assists in lowering the nose of the aircraft to prevent a stall caused by the aft CG position... 2021. 8. 10. PHAK Chapter 6-2 Introduction Introduction Current research at the National Aeronautics and Space Administration (NASA) Dryden Flight Research Center involves Intelligent Flight Control Systems (IFCS). The goal of this project is to develop an adaptive neural network-based flight control system. Applied directly to flight control system feedback errors, IFCS provides adjustments to improve aircraft performance in normal flig.. 2021. 8. 2. PHAK Chapter 6-1 Flight Controls Chapter 6 Flight Controls Introduction This chapter focuses on the flight control systems a pilot uses to control the forces of flight and the aircraft’s direction and attitude. It should be noted that flight control systems and characteristics can vary greatly depending on the type of aircraft flown. The most basic flight control system designs are mechanical and date back to early aircraft. Th.. 2021. 8. 1. 이전 1 다음 반응형
