The performance of such mixer ejectors is important in aircraft engine applications for noise suppression and thrust augmentation.
Recent hot-fire tests have validated the design approach and thrust augmentation ratios.
Calculations of nozzle performance and wall pressures were made using computational fluid dynamics analyses with and without thrust augmentation flow, resulting in good agreement between calculated and measured quantities including augmentation thrust.
The numerical results compare very favorably with nozzle experiments and both experiments and simulations validation the thrust augmentation concept.
Information on the mixing, pumping, ejector wall pressure distribution, thrust augmentation and noise suppression characteristics of four simple, multi-element, jet mixer ejector configurations is presented.
Rather than installing a larger engine to meet these requirements, it is more effective to add an afterburner to a turbofan engine as a means of thrust augmentation.
THE business of propelling large passenger jets is at maximum thrust.
Finally, influence of the specific impulse and maximum thrust magnitude on the fuel-optimal low-thrust formation reconfiguration is analyzed.
The thrust forces and moment are determined by the maximum thrust of the thrusters as well as the thruster configuration.
