Summary: Armstrong Siddeley Rocket Engine aircraft Airplane blueprint for the Armstrong, Siddeley, Rocket, Engine ... Aviation history and aircraft blueprints/plans. Armstrong Siddeley rocket engine - From just after the War the British developed the use of hydrogen peroxide to a fine art. As a rocket fuel it had a disadvantage that it was less energetic than some, but this was outweighed by many advantages.
Firstly, it was used a great deal on projects involving aircraft, and in service extensively with the R.A.F. From the crew point of view, this must have been by far the best choice of oxidant. There are hazards associated with liquid oxygen: for one, I would not like to be in a crash with an aircraft full of liquid oxygen. Another possibility would be fuming nitric acid, or dinitrogen tetroxide, but anyone who was has tried working with either will realise the problems involved. Instead, hydrogen peroxide could be handled relatively easily with a modicum of training, and it also has the advantage that it can be easily dispersed with copious qunatities of water.
Many of these powerful rocket engines were used for missile projects. The most unique use, was when fitted under the fuselage of aircraft. This blueprint is for the "Snarler" Armstrong Siddeley Rocket engine. Used liquid Oxygen and methanol/water. Rated at 2000lb
