During WW2 Nazi Germany developed Vengeance weapons against the British for their role in the bombing of Germany. The three weapons are the V-1, the V-2, and the V-3. They were all important in the develop of cruise missiles for the V-1 and ballistic missiles in the V-2. I will be talking about the V-1 today which used a pulsejet for power. https://en.wikipedia.org/wiki/Pulsejet

Diagram of a pulsejet
A pulsejet engine (or pulse jet) is a type of jet engine in which combustion occurs in pulses. A pulsejet engine can be made with few or no moving parts, and is capable of running statically (i.e. it does not need to have air forced into its inlet typically by forward motion).

Pulsejet engines are a lightweight form of jet propulsion, but usually have a poor compression ratio, and hence give a low specific impulse.

One notable line of research of pulsejet engines includes the pulse detonation engine which involves repeated detonations in the engine, and which can potentially give high compression and reasonably good efficiency.
Pulsejets are not used anymore because of their noise which can reach 140 Decibels which is as loud as an aircraft carrier deck. The https://en.wikipedia.org/wiki/V-1_flying_bomb only cost about 8000 us dollars in today money which is incredibly low and can deliver 2000 pounds of tnt but was only useful for large targets like cities. Battlefield 5 illustrates how the V-1 would have felt like in real life although the game is a bit unrealistic in terms of the accuracy and how the V-1 missile would have been useful but I have a video which shows the V-1 in the game right here but beware of the jump scare at 1:09
I was wondering what you guys thought about using a pulsejet in modern day cruise missiles if the noise could be decreased and if they accuracy was improved via GPS,INS, TERCOM, DSMAC, active radar homing and the altitude decreased to about 100-150 feet above ground level and speed which in the V-1 was about 400 increased by about 2-3 hundred mph. You can agree or disagree with me but I'm just looking at new military technology.
I have some designs for WW2 pulsejets used in the V-1 on this website. pulse-jets.com/

@waz @The Eagle please delete one of these, thanks

Surely the technology can be used as last resort for war, so it'll be a good idea to master it.. but there are other uses for it..

scramjet propulsion

What other uses do you see? I see only one besides a cruise missile. But, The reason I like pulsejet cruise missiles are that they can be upgraded a whole lot today when compared to the V-1 and made like a
Tomahawk missile setup with a rocket motor on the back igniting before the pulsejet ignites and mass production would be much easier as the pulsejet can be made pretty much any factory that has a minimal amount of metal working in a very quick manor. FADEC can be used to let the missile guide itself to its target with GPS and TERCOM and other guidance's also.






Lets move on what do you think of target drones using pulsejets? The costs would be very, very cheap just because the only things needed would be radio control and the target could be thrown into the air pneumatically in the same way as the Scan eagle.

For target drones they are OK, but for cruise missiles they are not stealth, which is a requirement!
They are useful in space missions.. try to read about it..

I have read about space missions it just hasn't interested me. What do you mean not stealth? Do you mean the sound of the engine or radar cross section? I was just proposing that pulsejets be used in any type of cruise missile and I think the cruise missile could be made stealth in body design.

Too much sound..

Too much sound..
If and only if the sound could be increased would you consider it viable as a cruise missile? There are some solutions proposed that I have read about that might be able to drown out the sound. Regular cruise missiles aren't quiet especially the low flying ones as evident in this video.

pulse jets were extremely noisy and fuel inefficient, your clip shows overhead noise which is too late for air defense to shoot it down and pulse jet have huge RCS as compare to turbofans and last they consider outdated tech @YvngEngineer
