ABSTRACT:
The crossover tube conducts fluid from the exhaust nozzle of a gas turbine engine to a blind receiver mounted in the sidewall of the airframe when assembled and deployed and includes a rigidly affixed forward ball and joint and a ball attached to the ends of each of a pair of tubes mounted in telescopic relationship with a clip secured to the coverplate covering the ball at the forward end cooperating with a pair of end to end mounted coil springs surrounding the tubes to hold the crossover tube in an erect and extended position to be guided into the receiver of the sidewall when deployed. In another embodiment bellows are utilized in place of the coil springs to provent leakage of fluid flowing in the crossover tube.
