“…41,42 Associated with the unsteadiness are issues of vibration and acoustics. The high stress levels from the propagating detonation waves may cause fatigue 43,44 although this has not been well investigated. Moreover, a unique thudding noise probably best described as a very loud jackhammer noise is produced by the PDE.…”

Rotating detonation engines (RDEs), also known as continuous detonation engines, have gained much worldwide interest lately. Such engines have huge potential benefits arising from their simplicity of design and manufacture, lack of moving parts, high thermodynamic efficiency and high rate of energy conversion that may be even more superior than pulse detonation engines, themselves the subject of great interest. However, due to the novelty of the concept, substantial work remains to demonstrate feasibility and bring the RDE to reality. An assessment of the challenges, ranging from understanding basic physics through utilizing rotating detonations in aerospace platforms, is provided.

“…Zhu et al [8][9][10] developed vast investigations on thermal fatigue behavior of ceramic thermal barrier coatings (TBCs) induced by laser. Later, they established a simulated engine test rig to evaluate thermal fatigue behavior of a candidate material for high-performance engines, and the material is tested under superimposed CO 2 laser surface impulsive thermal loads [11]. Long and Zhou [3] carried out experimental and numerical investigations on the thermal fatigue of particle reinforced metal-matrix composite induced by repetition-pulsed laser heating and mechanical load.…”

“…The results show that the test temperature field is well consistent with the target one in service. Based on the conclusion, typical thermal loading conditions [15,16], such as thermal high cycle fatigue and thermal low cycle fatigue, can be simulated by controlling the laser loading time or the temperature fluctuation range. The study will provide meaningful technical reference for the evaluation of laser thermal loading and damage on cylinder head.…”

In thermal fatigue test, the key point is whether the temperature field on the top surface of cylinder head induced by the heat source can well match it in real service. In order to produce the target temperature field in service which is measured by thermocouples, shaped laser beam generated by diffractive optics element (DOE) is chosen as the heat source to irradiate on the top surface of cylinder head. The DOE is designed based on the Gerchberg-Saxton (GS) algorithm and the simulated temperature field is calculated by finite element model (FEM). The results show that the simulated and experimental temperature field can well match the target one which demonstrates that this method is feasible to produce the target temperature field and can be used in thermal fatigue test.
