effects of divergence angle on moveable nozzle performance in thrust vector control system
in this paper, by numerical simulation of gas flow, effects of divergence angles on the amplification factor, side force and thrust vector magnitude of a moveable nozzle with supersonic split line have been investigated. the study is conducted for constant exit to throat area ratio and the location of the split line is also constant. the finite volume method with second order upwind scheme for ...
متن کاملA Computational Study on the Thrust Performance of a Supersonic Pintle Nozzle
Typical solid rocket motors (SRM) have advantage of their inherent simplicity and reliability, but they do not have the capability to change thrust profile like other propulsion system. Pintle technology is one of the means to achieve variable and programmable thrust. This paper describes a study of the static and dynamic characteristics of a pintle nozzle under the constant mass flow rate. The...
متن کاملNumerical Investigation in the Effect of Number of Nozzle Hole on Performance and Emission in Dual Fuel Engine
Air pollution is one of the major issues about the diesel engines in todays' world. It is a special concern in those areas that have difficulty meeting health-based outdoor air quality standards. Natural gas has low emission and resource abundance and also conventional compression ignition engine can be easily converted to a dual fuel mode to use natural gas as main fuel and diesel as pilot ...
متن کاملSelected Performance Measurements of the F-15 Active Axisymmetric Thrust-vectoring Nozzle
Flight tests recently completed at the NASA Dryden Flight Research Center evaluated performance of a hydromechanically vectored axisymmetric nozzle onboard the F-15 ACTIVE. A flight-test technique whereby strain gages installed onto engine mounts provided for the direct measurement of thrust and vector forces has proven to be extremely valuable. Flow turning and thrust efficiency, as well as no...
متن کاملExperimental Study on Performance of Two-phase Ejector Refrigeration Cycle System with Two-throat Nozzle
The two-phase ejector refrigeration cycle (TPERC) system with a two-throat nozzle ejector was investigated experimentally, and the entrainment ratio of the ejector and the COP of the system were compared with those of the ejector with Laval nozzle and its TPERC system respectively. The experimental results indicate that under the working condition of the evaporating/condensing temperatures 1°C/...
