Static tests of 65 inch diameter subscale rocket engines to evaluate nozzle fabrication methods, nozzle materials, liner material, case insulation, and propellant
Emittance as function of temperature for five ablative materials used as rocket engine liners
Arc driven shock tube with alumina ceramic liner to reduce driver gas contamination, noting shock speed and test time increase
Transient vibration analysis of liner systems using transition matrices
Aerodynamic, acoustic, and environmental criteria for noise reducing duct liners of turbofan engines
Dynamic stability and performance of injectors, rocket liners, and supersonic combustors
Arc driven shock tube with alumina ceramic liner to reduce driver gas contamination, noting shock speed and test time increase
Experimental research describes fluid flow and the fluid-elastic mechanism causing bellows flow excitation, and aids in design of conventional bellows liner which suppresses flow-induced vibrations. Analytical models facilitate prediction of flow excitation occurrence and estimation of severity of bellows vibrations.
Metal lined boron and graphite composites exhibit high strength and minimum weight, making them superior to aluminum cylindrical shell structures and to steel or aluminum constructed pressure vessels. S glass filament-epoxy resin matrix with aluminum liner is suitable for cryogenic tanks.
Creep characteristics of molybdenum at high temperature and stress are utilized to compress tungsten foil liner against inner surface of tantalum alloy cylinder to form bond at interface. Temperature and pressure can be accurately controlled and size of workpiece is limited only by furnace size.
Improved liner for Apollo lunar module descent engine injection chamber
Colloid annular thrustors performance tests in vacuum chamber with LN cooled liner, using high speed analog to digital system to acquire time of flight /TOF/ data
Buckling, fiber and resin thermal resistance, and hydrostatic tests of glass fiber reinforced spherical pressure vessels and liners
Ablation cooling in rocket engine with combustion chamber liner and nozzle constructed of silica phenolic ablative material
Turbofan engine noise reduction, using acoustic liners in inlet and exhaust ducts
Fan induced low speed jet noise from turbofan engines, discussing results of far field sound measurements for simulated nacelle configurations with and without acoustic liners
Elastic adhesive interlayer effect on bond fracture strength, considering propellant-liner- steel combination in solid rocket motors
New type of trifunctional alcohol was synthesized from commercially available trimer acid. Trifunctional alcohol is hydrocarbon with widely separated terminal hydroxyl groups, and was expressly developed as crosslinking agent for preparation of polyurethane propellants, binders and case liners.
