Spinal-Tap

On the optimization of thermally-choked ram accelerator systemsstribution along the multistage launcher. Two different approaches to the problem are presented and demonstrated: a) the practical approach, in which the solution is based on a finite number of available mixtures whose thermo-ballistic properties are known, and b) the mathematical approach, in which

Ram accelerator optimization and use of hydrogen core to increase projectile velocitydrogen core technique for ram accelerator operation between 3 and 7 km/s. Projectile structural design is studied; hollow, solid and two-material projectiles made of Mg, Al, Ti, steel, Ta and Re are analyzed to determine the maximum accelerations which can be reached. These projectiles are then anal

Ram accelerator performance modelingroat and that the aerodynamic drag can be determined independently. These propulsive mode models enable straight-forward evaluation of the performance potential of many different ram accelerator configurations.

Hiatal-Hernia

Numerical investigation on subdetonative mode ramjet-in-tubelow and equilibrium chemical reaction computation was tested. The various theoretical and experimental results encountered in the available technical literature were confronted with the numerical modelling developed in the present paper and the results correlated well.

JOT

Ram accelerator optimization and use of hydrogen core to increase projectile velocitye of a hydrogen core in the ram accelerator tube to reduce the heat flux to the projectile is studied. A new vortex technique is presented. With a projectile with a Ta or Re shell in a hydrogen core, one should be able to make the projectile survive up to launch velocities of 7 to 10 km/s.

Presentation of the rail tube version II of ISL’s RAMAC 30g smooth cylindrical projectiles was in use. In 1993 and 1994 the rail tube version I with four rails and since beginning of 1997 the rail tube version II with five inner rails is tested. In 1995 and 1996 the smooth bore technique was proved and the results are presented by Patz et al. (1997).
