ram jet not pulse jet

twin combustion chambers, running on lpg and compressed air made from several stainless steel coffee mugs, you got to love it..mad science at home..

Instead of forward movement to ram in the air we used an air compressor to ram it in.

i wish you had a better camera =[

[ST165SLEEPER]

its more of a lpg rocket than a ramjet

[DistooHH]

@sprocket2cog u gotta have a really good compressor then or not?

@knickknock4 Thanks for setting me straight :)

[Squarerig]

Thank you knickknock for the explanation.It does help when I actually understand what is going on before my eyes!

[knickknock4]

@Squarerig a ramjet system is usually built in the main engine which is usually a turbofan jet engine, the turbofan gives the jet a head-start and continues to run until it reaches its max speed at mach 3 subsonic speed, the ramjet system takes over after achieving mach 3 and continues supersonic flight at mach 5 to 7 and theoretically the scramjet takes over by shutting off the main engine inlets and diverting supersonic air into the scramjet, and then igniting and propelling towards mach 12

@nado2s ramjets work at mach 0.1 but don't give significant thrust until mach3.0 and will reach mach 5.5 to 7, a proper high speed wind-tunnel will make a ramjet work efficiently with the most power exerted, a scramjet however needs to be at mach 5 to 7 before it will run because it requires a huge amount of compression and heat, it can give a ridiculous amount of thrust and will continuously break the sound barrier at whats called "hypersonic speed", mach 12(current) to 24(expected).

[Squarerig]

I learnt that a ram-jet engine needs forward momentum for to feed air into the combustion chamber,so how does this function?

[krap101]

Don't ram jets need to be going at like mach 3 before they actually compress enough air to work?

Bloodseed. You also didn't have to spend a year repeatedly telling peeps that the video quality is shit. Who cares? By the way this isn't a ram jet AFAIK, a ram jet requires high speesd before it will even fire.. (Or is that a scramjet?)
