SR 71 Blackbird : Am I a joke to you ?π

These Mach 5 jet airliners are not going to happen. It is not the engines, it is the materials. We don't have supersonic jet airliners because sonic booms and the heat generated by air friction. Also, the SR71 had this type of transitional engine technology. Instead of trying to get there quicker, would be better off trying to reduce the time to get through the airport at both ends.

I've been in the aerospace industry most of my life and a mach 5 engine is not going to change air travel, what will change air travel is fuel efficiency and aerodynamic improvements to the Air frame....

I can guarantee you this aircraft falls firmly into the never ever going to happen category.

Thanx for explaining the shock waves produced in the ramjet design. It's the first time in any laymen-level tutorial that I have seen that this important design consideration has been mentioned. I like learning, finally, this small yet critical detail in the construction of the engine.

>Fun fact: The SR-71 already transitioned from TURBOJET to ramjet. BTW, that was a TURBOFAN in the video.

You're mistaking a turbofan for a turbojet. 4:08
A turbojet lacks a bypass. All air enters the comustion chamber. Turbofans can't really reach mach 1 since the intake fan tips begin exceeding the sound barrier drastically reducing engine efficiency.

I loved the detailed engineering explanation. Thank you for this video.
The first place I would fly would be Australia. That is a long haul from Western Canada!

the engine described at 4:16 is not a turbojet, that is a turbofan. Ramjet effect was described slightly incorrectly.

Idc if you can go ultrasonic, you have to stay subsonic over... basically all land.
I think this company has potential though. They found one of the key exceptions to the 'no sonic boom' bit, warzones.

4:05 that's a bypass engine.... Turbofan

Aerospace engineering is fascinating, the amount of regulations surrounding the development of any aircraft component is immense, which makes innovation in the industry extremely expensive and risky. That makes any sincere attempts at innovation in the aerospace industry extremely impressive and commendable. I hope they succeed!

Nosecone plus shockwaves = air valve. Got it. So maybe push the nosecone of the engine forward and back to adjust said shockwave to be optimal for a wider range of speeds.

Thank you for your great perspective on the New developments of the of the (ram) design iteration. My addition to your report concerning the innovation of the Delta Wing plane comparison would be that this motor would have to have a SUCCESSFUL life of development and use. Looking at the referenced Concorde (DELTA WING) design, we have only seen successful numbers of this design in military and experimental applications (widely). The Concorde was so plagued with complications and stresses that it finally met it's demise due to it's expense of operation. I believe that modern technology is catching up with the stresses that meet these Very Fast aircraft. Thank you again

The inflight entertainment might be this video!

Great video - thanks. But I was a little disappointed that you made no mention of the great British idea of the Skylon and the Sabre Engine, which also uses a pre-cooling system. I believe it converts from a Jet engine to a Rocket engine, at sufficient speed & altitude. The Skylon was a brilliant concept, but sadly, like a lot of good British ideas, always short of funding. Maybe you could make a video about it and give an update on what - if anything - has happened to the Skylon and the Sabre engine. Thanks again.

Imagine hitting a freak turbulence going Mach 5.
|
I believe evacuated tube technology is a faster, safer and more environmentally better solution. For transportation

the pre-cooler technology seems like the most interesting part of this. it seems that this is essentially the lynch-pin tech, even more important than the materials. how does the work of "Skylon" pre-cooler tech factor into, or compare with, that of Hermeus?

Minor point: Passenger jets are flying closer to .8M than .7M. A jet flying at .7M would not be allowed on the most used/popular Atlantic routes/altitudes -- at that speed it's blocking traffic.
