Title: Pipe-insulating shell with integrated spacer
IPC: F16L59/10
Filed: 1989-03-03
Abstract: Pipelines with a ventilated weatherproof casing expediently exhibit an insulation which consists of a mineral-fibre insulating material and into which spacers in the form of spacer rings are integrated. The integration of the spacer rings and/or of the parts jutting out beyond the surface of the insulating-material shells takes place in one operation by pressing in corresponding forms (moulds). The spacer rings then serve as a bearing surface for the weatherproof casing, possibilities for cross-ventilation between individual chambers arising due to corresponding notching or a corresponding tapered configuration. <IMAGE>

Abstract: Operation of a rocket-like propulsion aggregate, esp. for a helicopter blade tip motor, is carried out as follows. Either (a) decomposition of a monergolic propellant (I) in a catalyst pack in the reaction chamber is continued until the temp. of the hot gases exceeds a min. value and then (I) or a hypergolic propellant (II), which decomposes homolytically or hypergolically, is injected into these hot gases, so that at least the min. reaction temp. is maintained after the supply of (I) has been stopped; or two (II) are injected directly into the reaction chamber. Pref. the min. temp. is at least 430 deg. C.
