초록 ▼

This invention relates to a thrust reverser for aircraft jet engine having at least one door mounted to the downstream end of the jet generator to pivot about an axis which is transverse and at least substantially diametral to said jet, the door being able to pivot between a retracted position and an extended position. According to the invention, an at least partially supple seal is provided between the opposite parts of the inner and outer surfaces, respectively, of the door and of the jet generator, the transverse section of the seal being continually adapted to the space between the door and the jet generator in retracted position of the door.

대표청구항 ▼

A thrust reverser for an aircraft jet engine having a jet generator, comprising: at least one door mounted at the downstream end with respect to the jet generator to pivot about an axis which is transverse and at least substantially diametral to the jet from the jet generator; means for pivoting the door between a retracted position in which it forms a part of the nozzle of the engine and an extended position in which it is disposed at least substantially transverse to the jet, a space between the door and the jet generator being provided when the door is in its retracted position; and an at least partly elastic seal provided between the opposite parts of the inner and outer surfaces, respectively, of the door and the jet generator, the transverse section of the seal being configured to intimately contact the inner and outer surfaces for confining gas flow from the jet genrerator to exit from the jet engine at the downstream end of the jet generator only when the door is in its retracted position, the elastic property of the seal causing it to be pressed with increasing pressure to the contacting surface of the door, or the jet generator, as the pressure existing in the space between the door and the jet generator becomes higher, to thereby assist in preventing gas flow in the space from leaking upstream around the seal to the ambient environment, the elastic property of the seal further causing it to part from intimate contact with either the inner or outer surfaces when the pressure existing within the space between the door and the jet generator becomes less than that of the ambient environment to thereby allow air to be sucked into the space to equalize the pressure existing within the space to that of the environment.
