TLDR
In this article, a preliminary design procedure is presented for an SFRJ-assisted gun launched projectile of pseudo-vacuum trajectory, where two different types of regression rate mechanism are discussed: one controlled by the heat transfer processes downstream of the reattachment region and the other by that in the region itself.About:

Fuel Regression Rate in Hydroxyl-Terminated-Polybutadiene/ Gaseous-Oxygen Hybrid Rocket Motors
TL;DR: The results of a systematic experimental investigation on the methods of enhancing the regression rate in hydroxyl-terminated polybutadiene (HTPB) fuel used in an HTPB/gaseous oxygen hybrid motor are presented in this paper.

Role of Injection in Hybrid Rockets Regression Rate Behavior
TL;DR: In this article, a series of firing tests was carried out to investigate the influence of the oxidizer injection on the solid fuel regression rate behavior in a hybrid rocket engine, where a conical subsonic nozzle as the injector of the gaseous oxidizer was selected to generate nonuniform conditions at the entrance of the fuel port.

Effect of inlet conditions on swirling turbulent reacting flows in a solid fuel ramjet engine
TL;DR: In this article, an experimental and numerical investigation of turbulent reacting flows in a solid fuel ramjet engine with different inlet conditions is presented, where three main parameters were varied independently, which are the swirl intensity, mass flow rate, and air inlet temperature to study these parameters influence on the regression rate and combustion phenomena.

Heating and Ignition of Metal Particles in the Transition Heat Transfer Regime
TL;DR: In this paper, the authors considered the heating and ignition of small metallic particles in hot gases for a range of Knudsen numbers, for which the continuum description of heat transfer is not valid.

Flow Characteristics of Small-Sized Supersonic Inlets
TL;DR: In this paper, the flow characteristics of two types of small-sized supersonic inlet models were investigated for stable and unstable operating conditions of both models, and the main flow feature for stable operation is the existence of a shock train induced by the shock boundary-layer interactions.

Combustion of PMMA, PE, and PS in a ramjet
TL;DR: In this article, the authors investigated the combustion behavior of polymethylmethacrylate (PMMA), polyethylene (PE), and polystyrene (PS) with air in a connected pipe test facility; spectroscopy showed the presence of OH, C2, and CH and temperatures between 1300 and 3000 K during combustion.
