The results show that the effect of combustion efficiency on chamber pressure is limited, nozzleloss is mainly caused by its structure and size.
研究表明，补燃室压强的变化对燃烧效率的影响是有限的，喷管损失主要与喷管结构尺寸有关；

Under the same wall heat condition, with the increase of momentum correction coefficient, viscosity loss of the nozzle increases, but thrust and specific impulse decrease.
在同等壁面热条件下，随着动量调节系数的增加，喷管粘性损失增大，喷管的推力和比冲都将下降；

In the presence of the flow deflector, the generating of the vortices and the separating of the shear layer are avoided thereby the energy loss of the jet nozzle is reduced considerably.
