single detonation cycle meshed in ICEM and simulated in ansys fluent. Probably tomorrow i will complete the simulation Looks like the cj velocity matches my simulation.

Atlast completed my Msc in aerospace propulsion course writing my final thesis gonna submit it in a month. Hello everyone after nearly six months iam posting a new topic and finally i got some time to spend here in the forum. I would like to discuss about the integration of detonation engines into c...

WoW day by day the engine is getting perfected and iam very very eager to watch it running..

They are conical, the photo angle makes it look like it's cylindrical

oh iam sorry for that.

i have a question here why you didnt prefer to add conical augmenter to your engine. In an research paper by nasa says that conical Augs provide better performance than cylindrical.

wow looks giant iam eager to know when WILL you run this beast.

Regarding your design i would suggest you to add choke in between CC and exhaust. Tailpipe looks too long you can reduce it to 15" and make the intake length to 4.2inches. Flares are very important in valveless pulsejets because at higher throttle it helps the engine to breath easily. 1mm wall thick...

wow wow wow wow great absolutely great, looks gigantic its surely gonna be a tough job to fuel this monster. What is the overall length of the engine?

Monster started to take its form. Very curious to know how you are gonna fuel this beast.

yes sure i WILL test it. Can you say me Whats actually going on at that cone spot iam very curious.

Looking good! Now make a 2nd identical engine with just a straight pipe and see if there's a thrust difference Already my first attempt was with straight pipe still i didnt calculate the thrust difference but by seeing i can say that the cone transition design is much powerful than the straight pip...

Here is the video of my new engine. runs and screams awesome.

Yaaaay, engine ran successfully!!!!!! It started in first attempt itself. But unfortunately i kept my mobile in my room so wasnt able to take the video. I will post the video tomorrow. Got some pictures for you all.
