DEVICE FOR MEASURING THE LOADS OF A GLIDING PARASHUTE IN A WIND TUNNEL Russian patent published in 2022 - IPC G01M9/00 B64D21/00 

Abstract RU 2785085 C1

FIELD: aviation technology.

SUBSTANCE: invention is intended for determining the loads of a gliding parachute in a wind tunnel at various angles of attack and slip. The device includes a base with inclined support beams hinged to two U-shaped longitudinal beams with brackets, traverses, one-component upper tension-compression strain gauges fixed with three-stage hinges between the longitudinal beams and traverses in three mutually perpendicular planes. Traverses fastened to the mechanisms for fixing the parachute lines in its tip sections, are equipped with counterweights, the center of gravity of each traverse is aligned with the longitudinal axis of the traverse. Sling thimbles are fixed on the lower weight balances.

EFFECT: increasing the accuracy of load measurements due to the possibility of selecting measurement ranges.
