CA 2760045

An apparatus and method for in situ gas-phase formation and deflagration of nitrocellulose. A nitrating agent such as nitric acid and cellulose are delivered separately to a reaction chamber, where a brief heating pulse initiates nitration of the cellulose and deflagration of the nitrocellulose thus produced. Discharge of the high-pressure gases produced by the deflagration from the reaction chamber can then be used to drive an actuator, turbine, etc.

Linvention concerne un appareil et un procédé de formation dune phase gazeuse in situ et dune déflagration de nitrocellulose. Un agent de nitration tel que lacide nitrique et de la cellulose sont introduits séparément dans une chambre réactionnelle dans laquelle une brève pulsation thermique déclenche la nitration de la cellulose et la déflagration de la nitrocellulose ainsi produite. Lévacuation des gaz à haute pression produits par la déflagration à partir de la chambre réactionnelle peuvent ensuite être utilisés pour faire marcher un actionneur, une turbine, entre autres.
