A holding system () for holding at least one pipe, comprising a comb including a bar and parallel teeth perpendicular to the bar. A blocking device () consisting essentially of a pin, serves to prevent a pipe passing between two of the teeth from moving away from the bar. The holding system further comprises two supports (A,B), positioned at the ends of the comb, and which hold the comb so as to allow rotation thereof around the axis of the bar. A method for mounting a heat exchanger () comprising such a holding system.

A fastening method for fastening a tube () to a connector (), the method comprising the following steps: a) providing a connection kit comprising a sleeve, and a coupling for connecting together at least one pair of tubes, of generally tubular shape; b) placing the coupling in a first position in which the first end of the coupling projects outside the sleeve through a first end (A) thereof; c) then fastening the first tube in leaktight manner to the first orifice; d) moving the coupling relative to the sleeve into a second position in which the first orifice lies inside the sleeve; and e) with the coupling in the second position, fastening the sleeve () at a sufficient distance from the coupling (). A connection kit for performing the method.

A turbopump includes a turbine fed with hot gas, a pump driven by the turbine and fed with liquid fluid, and a hot gas exhaust pipe situated downstream from the turbine. The turbopump includes a bleed-and-injection circuit including a bleeder for bleeding the liquid fluid at the outlet from the pump, a heater for heating the liquid fluid as bled off in this way so as to transform it into gaseous fluid, and an injector for injecting the gaseous fluid into an interface region of the turbopump situated between the pump and the turbine, so as to optimize the flow and temperature conditions of the fluid entering into the turbine cavity in order to eliminate the vibratory phenomena that result from interaction between the fluid and the turbine disk.
