Ram jet boats
A ramjet, or athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the forward motion of the engine to produce thrust. Since it produces no thrust when stationary (no ram air) ramjet-powered vehicles require an assisted take-off like a rocket assist to accelerate it to a speed … Skatīt vairāk Cyrano de Bergerac L'Autre Monde: ou les États et Empires de la Lune (Comical History of the States and Empires of the Moon) (1657) was the first of three satirical novels written by Cyrano de Bergerac that … Skatīt vairāk The first part of a ramjet is its diffuser (compressor) in which the forward motion of the ramjet is used to raise the pressure of its working … Skatīt vairāk Ramjets can be classified according to the type of fuel, liquid or solid; and the booster. In a liquid fuel … Skatīt vairāk Ramjets generally give little or no thrust below about half the speed of sound, and they are inefficient (Specific Impulse of less than 600 seconds) until the airspeed exceeds 1,000 kilometres per hour (280 m/s; 620 mph) due to low compression ratios. Skatīt vairāk Air as it passes through a ramjet duct changes state (eg changes in temperature, pressure, volume) as it is compressed, heated and expanded in a thermodynamic cycle known as the Brayton cycle. This cycle also applies to the Skatīt vairāk Diffusers The diffuser is that part of the ramjet which converts the high velocity of the air approaching the intake into high (static) pressure required for combustion. High combustion pressures minimize wasted thermal energy … Skatīt vairāk A slight variation on the ramjet uses the supersonic exhaust from a rocket combustion process to compress and react with the incoming air in the main combustion chamber. This has the advantage of giving thrust even at zero speed.
