An experimental investigation of a thermal compression scramjet with OH imaging
, 2015 Scramjet engines must be designed to operate over a range of Mach numbers. In order to maintain robust starting characteristics at low freestream Mach numbers, the inlet contraction ratio must be minimized, reducing performance at high Mach numbers.

Numerical Study of Transverse Injection into Supersonic flow of the Scramjet Combustor [PDF]
فناوری در مهندسی هوافضا, 2018 Nowadays efforts for development of the scramjet engines are increased. Scramjet engines use atmospheric oxygen as an oxidizer therefore they don’t need oxidizer tanks, thus the weight of these systems is less than comparable rocket systems.

Thermofluidic compression effects to achieve combustion in a low-compression scramjet engine
, 2017 The compression provided by a scramjet inlet is an important parameter in its design. It must be low enough to limit thermal and structural loads and stagnation pressure losses, but high enough to provide the conditions favourable for combustion.
