Abstract:
The energy capabilities of acceleration devices are theoretically analyzed, including various ramjet-in-tube options for gas-dynamic acceleration of massive (1 to 40 kg) bodies under ground conditions up to velocities of 2–3 km/s. Simple quasi-one-dimensional models for a perfect gas are used in the computations. It is demonstrated that the use of a ramjet-in-tube with a closed exit allows the velocities of acceleration of massive bodies to be increased to 3 km/s, which is twice greater than the values that can be obtained with available gunpowder-based methods.
Keywords:
ramjet-in-tube projectile accelerator, accelerated body, acceleration barrel, gaseous combustible mixture.
