本文用一个简单的模型计算了简单喷气发动机和具有波转子顶循环的喷气发动机的热效率和比功率。波转子的性能是基于先前实验的测量结果。应用于马赫数为0.8的飞行器的情况，计算表明，与具有相同总压缩比的简单喷气发动机相比，具有波转子顶循环的发动机的热效率可提高约1%至2%，比功率可提高约10%至16%。如果波转子的性能能够得到改善，甚至可能获得更大的增益。
A simple model is used to calculate the thermal efficiency and specific power of simple jet engines and jet engines with a wave-rotor topping cycle. The performance of the wave rotor is based on measurements from a previous experiment. Applied to the case of an aircraft flying at Mach 0.8, the calculations show that an engine with a wave rotor topping cycle may have gains in thermal efficiency of approximately 1 to 2 percent and gains in specific power of approximately 10 to 16 percent over a simple jet engine with the same overall compression ratio. Even greater gains are possible if the wave rotor's performance can be improved.
