The effects of sonic vibrations on injector characteristics of liquid propellant rockets.
Colvin, Harold C.
MetadataShow full item record
Rocket instability is not very well understood in liquid propellant rockets. Propellant vaporization is one rate controlling process in the combustion process. The object of this investigation was to investigate the effect of sonic vibration on liquid drops in sprays and liquid jets. Difficulties were encountered in obtaining a suitable source that would give high intensity sonic vibrations. A loudspeaker unit was used to drive a resonant tube. The effects on liquid jets were photographed and interpreted. High speed photography was employed to observe the phenomena.
