GAS

GENERATOR_

Moog Bradford B.V. is partnering with a Dutch consortium including technology research institute TNO Defense, Security & Safety and CGG Technologies B.V., to jointly market the Cool Gas Generator (CGG) technology for spaceflight applications. In this symbiotic relation, TNO provides the technology and research capability while Bradford acts as the industrial partner, for the overall system design, manufacturing and verification aspects. The intellectual property rights are with CGG Technologies B.V.

The Cool Gas Generator is a unique technology that produces pure gas through decomposition of a solid material, while the gasses leave the gas generator at ambient temperature. Due to the unique design no external filtering or cooling is needed for the gas, this giving a high storage efficiency. The gas generators can be sized from very small to large, covering application areas from small nano-satellites to large inflatable structures such as airbag landing systems for planetary landers. Nitrogen and oxygen generators are available for space applications and a hydrogen generator is in development.

Advantages• Gas output at ambient temperature• Volume, packaging and mass efficiency• Long storage lifetime without leakage• Simple and modular technology

Solid PropellantCool Gas Generator

• Not pressurized until activation• No maintenance or pre-launch filling required• Space qualified technology
