METHOD FOR DROP WORK TESTS OF AN OBJECT ON A PARACHUTE SYSTEM WITH FORCED-FILLING IMPACT ATTENUATION BAGS Russian patent published in 2022 - IPC G01M7/08 G01M9/08 

FIELD: testing equipment.

SUBSTANCE: invention relates to testing equipment, to dynamic ground-based methods for drop work testing of objects on parachute landing (mainly free-form) systems with forced-filling impact attenuation bags with soft closed shells for operational or other specified loads when simulating landing on a parachute, on land and on water. Essence: the lifting of the object is carried out on a suspended system of a drop testing stand with a release lock with a parachute landing system placed on it, including skis with forced-filling impact attenuation bags with air ducts with loose soft closed shells, a pressure device with flaps connected to air ducts, and means of measuring and recording physical quantities on the object and on the shells to a height, providing a given landing speed, determined by the formula: where H is the lifting height: the distance from the landing site level to the lower surface of the landing means, m, V_l is the vertical landing speed of the object at the moment when the impact attenuation bag touches the landing site, m/s, g is the acceleration of free fall, g =9.81 m/s², h_A is the height of the air-filled impact attenuation bag, m. By launching the pressure device, soft closed shells are filled with air up to of a given overpressure, the flaps are closed, the release lock is triggered, the object is dropped onto the specified landing site of the drop testing stand.

EFFECT: creation of a method for drop work tests of various objects on parachute landing systems with forced-filling impact attenuation bags with soft closed shells for ground-based drop work tests and studies of the functioning of objects (including impact attenuation bags), including with loads, or dummies, or testers on universal seats inside the object, as close as possible to the actual specified landing conditions and making it possible to obtain objective results.
