Title: Water Injection
Post by: DPQ5 on June 01, 2008, 07:34:29 PM
Many allied aircraft had the ability to inject a limited amount of a water ethonal mixture into the engine to cool it down. This will allow longer weps for the out numbered pilot with 3 planes on his 6

What do you think 'WEP' is?

lol i realy dont know :rolleyes:
to me its just extra gogo power

Well why don't you look it up.  ;)

War Emergency Power....or more go go power as you so eliquently put.

This is the water injection your talking about.....tho we have a replenishing supply.

In RL they had a finite amount.

WEP should be finite in AH.  What is this?  Some kind of x-wing fighter game? :uhoh

What about AC that just use over boost? No additive is used. Once cooled, ready to use again.

Well, that's fine.  But if an aircraft had limited WEP, it should be the same in the game.

It is limited....however when the engine cools you regain some (not all I believe) of the available WEP.

War Emergency Power (WEP) is an American term for the throttle setting on some World War II military aircraft engines. For use in emergency situations, it produced more than 100% of the engine's normal rated power for a limited amount of time, often about five minutes.

Maximum normal power would be limited by a mechanical stop, for instance a wire across the throttle lever slot, but a more forceful push would break the wire allowing extra power. In normal service, the P-51H Mustang was rated at 1,380 hp, but WEP would deliver up to 2,218 hp. The Vought F4U Corsair, not originally equipped for WEP, later boasted a power increase of up to 410 hp (17%) when WEP was engaged. Several methods were used to boost engine power by manufacturers, including water injection and methanol-water injection. Some earlier engines simply allowed the throttle to open wider than normal, allowing more air to flow through the intake. All WEP methods result in greater-than-usual stresses on the engine, and correspond to a reduced engine lifetime. For some airplanes, such as the P-51, use of WEP required the plane to be grounded after landing and the engine torn down and inspected for damage before returning to the air.

The German MW50 system required additional piping, as well as a storage tank, increasing the aircraft's overall weight. Like other boost techniques, MW50 was restricted by capacity and engine temperatures and could only be used for a limited time. The GM 1 nitrous oxide injection system, also used by the Luftwaffe, provided extreme power benefits of 25 to 30 percent but required cooling on the ground and added significant weight.

Insert nice cut and paste here.

Until the water/alcohol mixture is depleted.  Then you should be S.O.L. until re-arm.

And no, you can't pee in the tank like they did in the radiator in the movie "Red Dawn"

Which of course brings up the Spits 5 min WEP limit.

The 5 minutes was a time limit after which the pilot had to inform the groundies. NOT a physical limit.

Spit pilots flew well past 5 minutes, the longest recorded being over 30 mins while being chased by a pair of 190's.

And how were the engine internals after inspection? *He asked knowingly.* ;)

Many combat a/c exceeded WEP limits, but then that would be abused by players since there is no penalty for engine wear, thus the 5 min limit. I agree on how they do it in AH. We have too many "gamey" tactics already due to there being no real consequences. Folks would go WEP for the entire flight (right at takeoff), every flight, if there was no artificial limit.

For the same reason we have limits on the speeds you can extend landing gear, flaps, and the same limits we have on structural strength, we must have limits on WEP.

In real life a B-17 *COULD* survive a direct hit from a flak and limp home on half a wing and a prayer. Realistically? This is the exception to the rule.

In real life a plane COULD run for 30 minutes on higher boost (also FYI the spit in the example didn't use additives, just higher settings), but what about the ones that didn't? They didn't make it home to tell the tale. The exception proves the rule in this case. Engines overheating and catching fire were common in WW2. Heck, some even caught fire when not in WEP mode.

Fine, at least that is what the source says.

We need the 5 minute limit to prevent abuse though.
