Fluid Mechanics of Pulse Pressure-Gain Combustors
46th AIAA Aerospace Sciences Meeting and Exhibit, 2008The fluid dynamic operation of a valveless pulse combustor has been studied experimentally and numerically. Through phase-locked chemiluminescence and pressure measurements it is shown that mechanical energy is created periodically in the flame surface, with an efficiency of 1.6%.

Gain of high-pressure CO₂ lasers
1978Previous theories of high-pressure C0₂ gain spectra have been modified to include gain contributions from the newly discovered 00°2 and 00°3 sequence bands. It is shown that the inclusion of these bands has important consequences for TE C0₂ lasers. At a pressure of 14 atm, the sequence bands typically cause a 40 percent increase in calculated gain at ...

Gain bandwidth products for capacitive pressure transducers
Applied Acoustics, 1994Abstract The compromise between the sensitivity and bandwidth of a pressure transducer using constant charge mode capacitive electro-mechanical transduction is examined. The performances of circular pressure summing diaphragms built around piston, plate and membrane structural elements are compared by defining a gain bandwidth product, analogous to ...

Valveless-Gas-Turbine Combustors With Pressure Gain
ASME 1958 Gas Turbine Power Conference and Exhibit, 1958A valveless combustor has been developed which has been tested at one to three atmospheres of pressure. It discharged combustion products at practical turbine-inlet temperatures and at a total pressure above that of the inlet. Developmental problems encountered and results are discussed.

Stimulated Brillouin Gain Spectroscopy at High Pressures
1991The use of spontaneous Brillouin spectroscopy with a Fabry-Perot interferometer is a well established, powerful technique for studying thermally excited sound waves in liquids and solids1–4. There are well known problems associated with the Fabry-Perot interferometer, however.
