2. Tsiolkovsky rocket equation - Wikipedia

   en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

   A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...

3. Dirac delta function - Wikipedia

   en.wikipedia.org/wiki/Dirac_delta_function

   As a result, the nascent delta functions that arise as fundamental solutions of the associated Cauchy problems are generally oscillatory integrals. An example, which comes from a solution of the Euler–Tricomi equation of transonic gas dynamics , [ 61 ] is the rescaled Airy function ε − 1 / 3 Ai ⁡ ( x ε − 1 / 3 ) . {\displaystyle ...

4. Specific impulse - Wikipedia

   en.wikipedia.org/wiki/Specific_impulse

   Specific impulse should not be confused with total thrust. Thrust is the force supplied by the engine and depends on the propellant mass flow through the engine. Specific impulse measures the thrust per propellant mass flow. Thrust and specific impulse are related by the design and propellants of the engine in question, but this relationship is ...

5. Impulse (physics) - Wikipedia

   en.wikipedia.org/wiki/Impulse_(physics)

   The impulse delivered by a varying force is the integral of the force F with respect to time: =. The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unit of momentum is the kilogram metre per second (kg⋅m/s).

7. Rocket propellant - Wikipedia

   en.wikipedia.org/wiki/Rocket_propellant

   The primary specific impulse advantage of liquid propellants is due to the availability of high-performance oxidizers. Several practical liquid oxidizers ( liquid oxygen , dinitrogen tetroxide , and hydrogen peroxide ) are available which have better specific impulse than the ammonium perchlorate used in most solid rockets when paired with ...

8. Liquid rocket propellant - Wikipedia

   en.wikipedia.org/wiki/Liquid_rocket_propellant

   The highest-specific-impulse chemistry ever test-fired in a rocket engine was lithium and fluorine, with hydrogen added to improve the exhaust thermodynamics (all propellants had to be kept in their own tanks, making this a tripropellant). The combination delivered 542 s specific impulse in vacuum, equivalent to an exhaust velocity of 5320 m/s.

9. Liquid-propellant rocket - Wikipedia

   en.wikipedia.org/wiki/Liquid-propellant_rocket

   Problems with burn-through during testing prompted a switch from gasoline to less energetic alcohol. The final missile, 2.2 metres (7.2 ft) long by 140 millimetres (5.5 in) in diameter, had a mass of 30 kilograms (66 lb), and it was anticipated that it could carry a 2 kilograms (4.4 lb) payload to an altitude of 5.5 kilometres (3.4 mi).
