Investigation of Tension Force Adjustment in T-34C Aircraft Main Landing Gear Wheel Doors

Abstract

The purpose of this thesis is to research and investigate main landing gear door malfunctions that frequently occur in T-34C aircraft Aircraft airflow changes continuously in the air In order to find the reason for landing gear malfunctions I proposed a hypothesis with fixed characters and values in a real situation I collected the frequency of discrepancies in T-34C aircraft in 2014 According to the technical order and operating principles of the T-34C landing gear system I posited that there is a pressure difference between the inside and outside of the landing gear cabin when the aircraft are in the air I calculated the force of the T-34C airfoil (NACA23016) in CFDRC when aircraft fly at 90 100 110 120 knots per hour at an altitude of 10 000 ft The results of experiments indicate the following: 1 Technicians need to adjust the landing gear tension (54-67 pounds) 2 The pilot should put the landing gear up when flying at speeds over 100 knots per hour
