Abstract

The invention discloses a multiple protection integrated helicopter anti-crash seat which comprises a main skeleton, a weighing sensor, a magneto-rheological damping system, an upper torso forced tightening and quick releasing system, a seat bucket, a multifunctional vest and a controller; the seat bucket is in sliding connection with the main skeleton in a vertical direction; the magneto-rheological damping system is fixedly arranged on the seat bucket and is connected with the main skeleton through the weighing sensor; the upper torso forced tightening and quick releasing system is arrangedon the seat basin; the multifunctional vest is connected with the seat bucket through the upper torso forced tensioning and quick releasing system; and the controller is respectively connected with the weighing sensor and the magneto-rheological damping system. The multiple protection integrated helicopter anti-crash seat has excellent anti-crash performance and protection performance, can provideoptimal protection for all percentile occupants, enables a pilot to maintain an optimal posture, prevents secondary collision, has a quick releasing function, can realize one-key unlocking, and meetsthe life-saving requirements for various complex environments after the pilot falls.

Description

technical field [0001] The invention relates to the technical field of aviation equipment, in particular to a helicopter anti-crash seat integrated with multiple protections. Background technique [0002] At present, domestic helicopter anti-crash seats adopt fixed-load energy-absorbing technology, but fixed-load energy-absorbing technology can only provide pilots with a specific weight (in order to maximize the performance within the pilot's weight range, generally take the weight of the 50th percentile pilot) Optimal protection, less effective for pilots who are too light or heavy; for heavy pilots, moving downward with less than expected deceleration may result in insufficient shock travel, causing a secondary impact; and light weight pilots However, the pilot cannot make full use of the effective impact stroke, and may experience a higher than expected deceleration impact, which exceeds the tolerance of the human body. Therefore, in order to ensure that the energy-absor...
