Founded in 1995, China Dongda Power Industry Co., Ltd. is one of the few solid rocket motor manufacturer and distributor in China that has patents on the generator, motor, power supply, engine, alternator, diesel and gearmotor design, supply and sale. Our custom solid rocket motors has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. Our 30 QC staff carefully performs inspections at every stage of production, from the time we receive raw materials to packaging. Noise, power, and stability are tested to ensure that our engines can endure 580 hours of constant use. We also can design and deliver OEM/ODM samples in one month.

Solid rocket motors generate their thrust by burning a solid propellant to generate hot gases, which are exhausted through a converging-diverging nozzle. Current nozzles are often made from a variety of metal alloys, carbon-carbon or carbon phenolic composites, which are able to withstand the high temperature and pressure environment, but are heavy and expensive. Because of its unique combination of mechanical and thermal properties, Touchstone's Carbon Foam offers the potential for significant improvements in solid motor nozzle technology. Touchstone's Carbon Foam is low cost, lightweight, strong, and has thermal properties well suited to the extreme conditions.

The simplest of all rocket propulsion system designs. A solid-propellant rocket motor consists of a casing, usually steel, filled with a solid propellant charge, called the grain, which contains all the chemical constituents (fuel plus oxidizer) for complete burning. When ignited, the propellant compounds burn rapidly, expelling hot gases from a nozzle to produce thrust. The propellant burns from the center out toward the sides of the casing. The shape of the center channel determines the rate and pattern of the burn, thus providing a means to control thrust. Unlike liquid-propellant engines, solid-propellant motors can't be shut down. Once ignited, they burn until all the propellant is exhausted.
