Abating exhaust noises in jet engines [PDF]

, 1974
A noise abating improvement for jet engines including turbojets, turbofans, turboprops, ramjets, scramjets, and hybrid jets is introduced. A provision is made for an apparatus in the primary and/or secondary flow streams of the engines; the apparatus ...

The design of a labyrinth seal to replace the centrifugal compressor of a turbojet, for transforming the turbojet into a turboexpander

Technium: Romanian Journal of Applied Sciences and Technology
In the last 10 years, the development of microturboreactors has experienced an exponential evolution. They have recently gained interest due to the significantly higher power output, which is primarily achieved by expanding the speed ranges of the key components, namely the compressor and the turbine.

Heat-Transfer Characteristics of Partially Film Cooled Plug Nozzle on a J-85 Afterburning Turbojet Engine [PDF]

Plug nozzle film cooling data were obtained downstream of a slot located at 42 percent of the total plug length on a J-85 engine. Film cooling reduced the aft end wall temperature as much as 150 K, reduced total pressure loss in the upstream convection ...
