High-test peroxide (HTP) is a highly concentrated (85 to 98%) solution of hydrogen peroxide, with the remainder consisting predominantly of water.In contact with a catalyst, it decomposes into a high-temperature mixture of steam and oxygen, with no remaining liquid water.
Kerosene + (high-test peroxide + catalyst) – Gamma, with the peroxide first decomposed by a catalyst. Cold hydrogen peroxide and kerosene are not hypergolic, but concentrated hydrogen peroxide (referred to as high-test peroxide or HTP) run over a catalyst produces free oxygen and steam at over 700 °C (1,300 °F) which is hypergolic with ...
The oxidiser used with Gamma was 85% high-test peroxide (HTP), H 2 O 2. Gamma used a silver-plated on nickel-gauze catalyst to first decompose the peroxide. [15] For higher concentrations of H 2 O 2 another catalyst would have been required, such as platinum.
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
Aerojet S-405 is a spontaneous catalyst, that is, hydrazine decomposes on contact with the catalyst. The decomposition is highly exothermic and produces a 1,000 °C (1,830 °F) gas that is a mixture of nitrogen, hydrogen and ammonia. The main limiting factor of the monopropellant rocket is its life, which mainly depends on the life of the catalyst.
The rocket system consisted of a hemispherical HTP tank on the top of the rotor head and pipes running through the blades to catalyst chambers and rocket nozzles at each blade tip. Total thrust was 22.5 lbf (0.10 kN) thrust for 15 minutes, at a total HTP consumption rate of 1 imp gal/min (1.2 US gal/min; 4.5 L/min), boosting rotor power by 67 ...
A subsequent investigation concluded that high-test peroxide (HTP), a form of highly concentrated hydrogen peroxide used as propellant for the torpedo, seeped through a faulty weld in the torpedo casing. [16] When HTP comes into contact with a catalyst, it rapidly expands by a factor of 5000, generating vast quantities of steam and oxygen.
HMS Explorer was an Explorer-class submarine, an experimental British submarine based on the captured German high test peroxide (HTP) powered U-boat U-1407. U-1407 had been scuttled following the German collapse at the end of the Second World War, was salvaged and eventually commissioned into the Royal Navy as HMS Meteorite.
