It is important for success, that on engine technology and flight control software and engine (included the Vector thrust jet nozzle) integration of design, and Boeing’s decision to use a direc-lift,as short take-off and vertical landing(STOVL)propulsion system was the main weakness in its unsuccessful JSF bid.
Moreover infrared characteristics of a rocket motor nozzl was calculated,and effective and net radiative heat flux of the nozzle in mid-wave infrared band 2~6 μm,long-wave infrared band 8~14 μm and full wave band were analyzed.
Analysis of the thrust characteristics of jet nozzles designed by various methods
A comparative numerical analysis of the thrust characteristics of axisymmetric jet nozzles designed by various methods is carried out.
For optimization of beam generation different nozzle types (smooth jet nozzles, turbulent working nozzles) have been compared at different pressures.
A representative resonator performance is simulated and it is shown that velocities above 16?m/s are expected at jet nozzles.
Utilizing magnetically controlled drop-on-demand ink jet nozzles, an r/? array format of 2500 spots can be simultaneously dispensed from up to 24 separate reagent valves onto a rotating disc as the solid phase in less than three minutes.
Spatial-energy, spectral, and optical characteristics of kilowatt supersonic cw HF chemical lasers of self-contained type with three-jet nozzle arrays using nozzle-nozzle-injector and nozzle-nozzle-nozzle configurations were experimentally studied.
In this paper, a computational study was performed to explain the flow field in the air jet nozzle with an acceleration tube and validated with previous experimental data available.
Flow of an anomalous viscous fluid in a centrifugal jet nozzle
For the first time this sample-introduction beam has been generated at low pressure by use of a peristaltic pump and a special micro channel smooth jet nozzle developed for this application.
Numerical solutions are obtained for the jet Reynolds numbers 200-2000, jet mouth-to-surface distances 1-4 times the jet nozzle diameter, and for helium-4, air, and carbon dioxide.
