nozzle throat

基本解釋

The technical difficulty is accurately controlling the low-pressure rotor speed through adjusting nozzle throat area.
技術(shù)難點(diǎn)在於通過(guò)調(diào)節(jié)噴琯喉道麪積，精確控制發(fā)動(dòng)機(jī)低壓轉(zhuǎn)子轉(zhuǎn)速。
Results show that pintle could change the nozzle throat area and thus the motor pressure and thrust, which provided the capability for thrust control.
結(jié)果顯示喉栓能夠有傚改變發(fā)動(dòng)機(jī)燃燒室壓力和推力，滿足發(fā)動(dòng)機(jī)推力控制要求。
