A variable 3D CD nozzle includes: a flexible body defining a flow path having an inlet extending through a narrowed throat to an expanded outlet, wherein the flexible body comprises a plurality of flexible members movably interconnected together; and at least one means for changing a shape of the flexible body to change a dimension or location of the throat plane relative to at least one of the inlet plane or outlet plane. A method of changing airflow in a nozzle includes operating at least one means for changing the shape of the flexible nozzle body to change the dimension or the location of the throat plane. A method of testing an object includes placing a test object in the test region of the test cell and passing a test gas from the outlet opening of the nozzle onto the test object.

Variable three dimensional convergent-divergent nozzle

An apparatus is provided for burning a fuel and nitrous oxide. The apparatus has a combustor, a catalyst, a nitrous oxide supply passage for directing the nitrous oxide to a contact position with the catalyst, and a fuel supply passage for supplying the fuel to the combustor. The catalyst is for facilitating decomposition of the nitrous oxide, and the combustor is for burning the fuel, the decomposed nitrous oxide and/or further nitrous oxide decomposed in the reaction.

Burning nitrous oxide and a fuel

A rocket engine having a combustion chamber with a chamber inner wall, a throat with a throat inner wall, and a nozzle with a nozzle inner wall is provided. The chamber inner wall is a vacuum plasma sprayed metal, the throat inner wall is a vacuum plasma sprayed metal, and the nozzle inner wall is a vacuum plasma sprayed metal. The porosity of the vacuum plasma sprayed metal varies in an axial direction of the engine.
