Ramjets and Scramjets Explained - Mach 14

Flat ion engine

No , "we" haven't.

M<?? Sounds fast to me. I cant wait to see what Skylon has in store for us.

Two engines in one? Could a ramjet be engineered to expand into a scram jet?

What about making the inlet wider?
-To increase air flow?

so how do these work in space with no air

Absolutely clear explanation.

My other question is regarding the quest for hypersonic cruise missiles. From what I understand, ramjet engines are well demonstrated, and if they can infact reach Mach 6 or so, couldn't a ramjet powered cruise missile just be launched from a plane with a conventional solid rocket booster to accelerate it to mach 3+ and then detach like a rocket? If scramjets are more developed than I thought, the same logic applies.

Hypothetically, is there the possibility of an engine yet faster than that, where the flow of the air in the combustion chamber is still flowing at hypersonic speed, allowing velocities in the mach 20 or 25+ range? I understand the material science issues related to heat, hence the hypothetical.

To go beyond Mach 14 we need WHAMBAMJET then beyond Mach 20 POWWOWJET. Done I present to you my contribution to Jet Research, the names.

If we could create an adjustable aircraft with a jet engine and afterburner that then activates a ramjet when at top jet engine speed with the jet engine retracting into the aircraft body or closing off the engine aerodynamically.

Then as the ramjet approaches maximum power, morph the design with hydraulics into a scramjet configuration to utilize a scramjet to get to top mach speeds.

Place a rocket engine onboard as well and have that fire up at maximum scramjet speeds. Close off the scramjet while the rocket fires and this vehicle can hit mach numbers upwards of 15+.

If a lot of the wings and parts are dynamically controlled to morph in shape and position through these various stages of flight, then the vehicle might be capable of going from takeoff to mach 15+ and then returning back to land.

The engineering would need to be exceptional, the meta materials at the forefront of materials science, and the fuel consumption planning precisely calculated, but as a grand experiment such a craft could prove very versatile for very specific missions.

So a lot of these UAPs we seeing are just $NOC 😮

The acceleration has to hurt.

U Brits R still using that antiquated metric system? 😜

How fast would you say the SR71 flew ? We may never know. I am sure the thrust was at least 30 % higher at the end of the program over the 45K starting thrust.

Here's the solution to the temperature and pressure being to high in Ramjets to get good combustion. As the Ramjet approaches the highest speeds possible for the fuel to burn properly, instead, add water into the combustion chamber, then the water will expand and add to the thrust. Is this possible.

I once knew a guy called Ramjet. Roger I believe.

When he said a jet engine can get you up to 1 KM a second, it really put the speed into perspective. A person running at full speed can do that in maybe 5-6 minutes. A car on the highway does that in about 1 minute. By the time you finished reading my comment that plane would have already flown about 20 KM.

Great explanations mate

So in practical use, would a ground based aircraft need all three types of engines to get from hangar to Mach 10?

Excellent presentation.

Thank you .

why can't scramjet engines be used instead of rocket engines on rockets,
where fuel is fed into the scramjet engine and when sufficient speed is achieved, then scramjet switches to airbreathing with fuel injection and then when rocket leaves atmosphere, then fuel is fed into scramjet again, some fuel could be save which could make rocket lighter

👍

You have a room where you can generate mach 3 winds, can we see that?
so because a Rocket needs to carry it's own Air it is significantly heavier...

Theoretically, could we drop something from orbit (maybe similar to the lifting body escape things on the ISS), and actually test scramjets from orbital velocity, or would we have issues starting from the peak and working down

Fantastic presentation

The Russian Avangard's speed is reportedly Mach 20 - Mach 27. It has a solid propellant scramjet engine.

We need Ludicrous speed now!

ranjet is incredible

What about using a nuclear pile to heat the gas instead of combustion. The advantage here would be you could keep the gas flowing very hypersonic, would not necessarily need to be slowed down, and heat it with a nuclear reaction. You could theoretically heat it to about 2500K from 300K. Also, as the efficiency drops it could convert over to a pure nuclear rocket and obtain orbit that way?

Nash . Needs someone with the knowledge having been there too.
Thanks.

Where are impulse & warp, are they in the next lecture?

Latticed over each other in a donut with a gyro cockpit

Can the jets be arranged along the centerline in order of speed for efficiency?

nice vid bro

I hope they add all of these to KSP 2...

what comes next? hcramjets? (hypersonic combustion ramjets) or is that just really fast scramjets?

we have an engine that can convert from a normal jet engine to a ramjet engine already, given that the mach ranges overlap for all 3 designs in this video I can't see why some supernerd engineer can't work out a way to transition between all 3 forms in one contained unit.

Why do you need to go mach 14+ with a scramjet? Why not just use a rocket?

Jet engine theory in 4 words. Suck, squeeze, bang blow.

what about the shockwave inside the nacelle ? if it moves too much aft , it might flame out the engine . just as it happened when the sr71 tried to reach m3.5

Who's here after Top Gun Maverick?

The Russiaqns have done it!
They have mastered scram engines...

Good video! Here after watching Top Gun: Maverick.

very informative, thank you
