Randomized trial assessed thermodynamic efficiency and fuel demand in a hypersonic vehicle, suggesting improvements for future designs.

Key Points

This research aims to integrate a dynamic model with thermodynamic analysis for a scramjet-powered hypersonic vehicle to enhance performance evaluation.
Developed a six-degree-of-freedom (6DoF) dynamic model integrated with thermodynamic representation of a scramjet vehicle.
Validated the model through simulations of high-speed cruise from 65,000 to 100,000 ft at Mach 10.
Analyzed fuel mass flow rates and thermodynamic efficiency at various Mach numbers.
Scramjet operation enhances thermal and exergy efficiencies to over 70% at Mach 10; propulsive efficiency not included.
Fuel mass flow rates stabilize above 6.5 kg/s at Mach 10, compared to below 3 kg/s at Mach 5.
Intermediate Mach regimes (7-8) showed a balanced operational condition between efficiency and fuel consumption.
