Measuring of a Nose Landing Gear Load during Take-Off and Landing

Applied Mechanics and Materials, 2016
This article provides information about in-flight measurement of a small sport aircraft. The strain gauges were used as sensors for load monitoring on the nose landing gear structure. To obtain overall forces it was necessary to do the calibration procedure. After the calculation of strain gauge coefficients the equations for calculating of total force,

Cracking in an Aircraft Nose Landing Gear Strut

1993
Abstract A crack was detected in one arm of the right-hand horizontal brace of the nose landing gear shock strut from a large military aircraft. The shock strut was manufactured from a 7049 aluminum alloy forging in the shape of a delta. A laboratory investigation was conducted to determine the cause of failure. It was concluded that the

Conceptual design and linear static analysis of nose landing gear

2015 International Conference on Robotics, Automation, Control and Embedded Systems (RACE), 2015
Landing is one of the most maneuvers occurring in aircraft. Landing gear is considered as a nonlinear structure due to its complicated behavior. In this paper we did linear static analysis of nose landing gear of a subsonic civil transport aircraft. During landing period large amount of impact forces are transferred into nose gear and main landing gear.
