1. Advanced Aspide rocket motor

2. A particularly simple form of rocket motor uses solid propellant.

3. Computational result of free - efflux field for one rocket motor has been presented.

4. The influence of structure axial vibration on the internal ballistics of solid rocket motor was investigated.

5. The rocket motor ignites 1.5 seconds after firing the missile, and it burns for 6 seconds.

6. After one second, controls in the nozzle of the rocket motor start steering the missile on to the proper trajectory.

7. The Grot Bomm takes the form of a heavy ballistic rocket that combines a short-burning rocket motor with a heavy explosive warhead

8. Traditionally, the tempurature of Solid Rocket Motor (SRM) is predigested as invariableness and uniformity, but the protean and unhomogeneity of tempurature are rarely involved.

9. A space animator even took the time to use a 3-D modeling program to show how the rocket motor could have made what seems a bizarrely regular shape.

10. SpAceshipOne is an experimental air-launched rocket-powered aircraft with sub-orbital spaceflight capability at speeds of up to 3,000 ft/s (900 m/s), using a hybrid rocket motor

11. The subject of the invention is a spacecraft afterbody device provided with at least one rocket motor (2) at the rear of the craft characterized in that it comprises at least one manoeuvrable cowl element (3, 3a, 3b, 3c, 3d), suitable for taking a first position, for masking and for reducing the rear drag of the craft, where it extends the fuselage of the craft around at least a part of a nozzle (4) of the rocket motor of the craft and stretches beyond the rear of the fuselage of the craft, and for taking a fully deployed second position for increasing the aerodynamic drag of the craft.
