Each of the tubes of the tube thrust chamber of a rocket engine is hooked at either end with the end at the outlet oriented horizontally relative to the rocket engine's center line and the end at the inlet oriented vertically and bent outwardly away from the rocket thrust chamber and facing the outlet for fitting into apertures formed in the outlet and inlet manifolds. The method of construction and assembly is manifested by assembling the sub-assembly of the wedge ring/manifold above the open ends of the vertical portion of the tubes and lowering the assembled wedge ring/manifold so that each tube fits into complementary apertures formed in the inlet manifold and the wedge ring tightly fits onto the outer periphery of the tubes and brazing this assembly in situ. A skirt extends below the thrust chamber and includes a planar surface for resting on ground to support the thrust chamber in an upright position.

Tube rocket thrust chamber construction and method

A high performance rolling element bearing (5) which is particularly suitable for use in a cryogenically cooled environment, comprises a composite cage (45) formed from glass fibers disposed in a solid lubricant matrix of a fluorocarbon polymer. The cage includes inserts (50) formed from a mixture of a soft metal and a solid lubricant such as a fluorocarbon polymer.
