NICOP - Sustained High Altitude Solid Fuel Ramjet Operation - Flammability Limits for Large Caliber Extended Range Applications
Abstract
The Netherlands Organization for Applied Scientific Research TNO performed the World~s first successful demonstration of a 35 mm spi"n-stabilized air defense projectile capable of maintaining its initial flight velocity at 1400 m/s. In addition, over the years TNO" has performed extensive tests on different types of fuel covering fuel grain sizes representative for projectiles ranging from medium to large caliber. Combining this propulsion technology with guidance and control techniques offers dramatically improved effectiveness of gun fired ammunition. Applications may range from medium caliber direct hit or direct fire to large caliber indirect fire ammunition.The research goal of the present proposal is to develop a model to predict the flammability limits of a SFRJ combustor as a function of flight Mach number at operational conditions representative for the high altitude flight phase of gun launched large caliber extended range applications and to validate this model by doing dedicated SFRJ experiments. A publication on the flammability model and its validation will be generated.A thorough understanding of the operational limits of SFRJ propulsion systems as dictated by flammability limits of the combustor and intake subsystem performance of a SFRJ propulsion system both at high altitude and transient conditions is a prerequisite for successful application of this technology for large caliber extended range projectiles as well as for missile applications
