Application Note: Jet parachute deployment test

By FUTEK Engineering

For short runway and/or high-speed landings, military aircraft use parachutes to safely stop the vehicle. These parachutes are tested in full-scale wind tunnels to measure the drag force they generate, and the aircraft structure must be able to withstand the drag force without failure.

By harnessing an in-line load cell, test engineers can accurately measure the drag force of the parachute, the load on the airframe, or the completed system in real time.

Products in use: In-Line Load Cells (Standard LCM Family or customized).

How it works

1. When runway length is tight, military aircraft deploy parachutes to assist in rapid deceleration.
2. These parachutes require extensive precision and endurance (fatigue) testing prior to use.
3. Utilizing either standard or customized In-Line Load Cells in a wire-tension measurement application allows quality inspection engineers to audit the tensile forces applied to the parachute cable throughout deployment and use.
4. These tensile forces can be read on a number of instruments, including the FUTEK digital displays (IHH500 or IPM650) or streamed to a PC via FUTEK USB Solutions.
