Propulsion engine

Practical experience has shown that, depending on the field of application, a considerable reduction in inspection costs can be had when opting for radioscopy rather than radiography. By comparison with film technique, the inspection time of turbine blades for aircraft jet propulsion engines is reduced by 45% to 60%. When adding film costs, approximately DM 450.000,- can be saved per year /3/. As far as... 

SiHcon nitride (see Nitrides) is a key material for stmctural ceramic appHcations in environments of high mechanical and thermal stress such as in vehicular propulsion engines. Properties which make this material uniquely suitable are high mechanical strength at room and elevated temperatures, good oxidation and creep resistance at high temperatures, high thermal shock resistance, exceUent abrasion and corrosion resistance, low density, and, consequently, a low moment of inertia. Additionally, siHcon nitride is made from abundant raw materials.

One assumes a propulsion engine operated in the atmosphere, as shown in Fig. 1.3. Air enters in the front end i, passes through the combustion chamber c, and is expelled from the exit e. The heat generated by the combustion of an energetic material is transferred to the combustion chamber. The momentum balance to generate thrust F is represented by the terms ...

According to McLarren [52] a mixture with methyl alcohol has frequently been used in rockets, to react with hydrogen peroxide. E.g. in the HWK-59 jet propulsion engine and BP-20 rocket missiles 80% hydrogen peroxide is used as an oxidant together with a combustible consisting of ...
