Title: P-38 Compressibility flaps
Post by: earl1937 on October 04, 2012, 05:04:32 PM
 :airplane: Would love to see Hi Tech add the compression flaps to our 38L's...this feature was added on the real ones due to compressibility problems with the aircraft....sure would save some "lawn darting" I see in the arena's

lawn darting?

Shift C

We already have them.

P-38L has dive flaps...another wish granted!

I do believe what you are asking for is already there, at least on the P38L.  It is that model that has the "dive recovery flaps".  They are not dive breaks, flaps, or anything else.  Their sole purpose is to help the P38 recover from a high speed dive.  I suggest you deploy them prior to obtaining 430mph TAS and do it before you get to 5000 ft of altitude, they need time to work.   :aok

:airplane: Sorry "charlie", not talking about dive flaps....the compression flaps I am referring to are on the bottom of the wing, 16 inches back from wing center and they "pitch" the nose of the 38 up, if you get into compressibility realm and controls quit working. They would pitch the nose up and with a power reduction, the pilot could recover quite well.....Richard Bong, the top rated ace in WW2, used these flaps a good bit in his ACM during the war.

That is what the P-38L has.  It doesn't have "dive flaps" like a dive bomber.

What you are asking for is already modeled in AH.

Like I already mentioned, the P-38L in game has dive flaps to aid in recovering from a high speed dive.

As you can see from the above picture, those are the dive flaps, which is the correct name for what you're referring to.

Actually this isn't true as the majority of Bong's kills were in earlier versions of the 38.  The first L's didn't get there until late and there is a photo of Bong with 27 kills marked on his 38 and it's a J-15

:airplane: Well, I stand corrected! I've tried the "dive" flaps, 6 ways to Sunday, and can't tell any difference with or with-out flap application. Guess I will have to go back to TA and do some more test!

If you're looking for them to eliminate compressability, you're going to be unhappy. They merely raise the speed of the onset of compressability, mitigate to some degree the effects, and aid in recovery.

They work exactly as they should, they even give a momentary pitch up when deployed outside of their normal operational envelope.

By the way, you should not reduce power.

If you're locking up a P-38 in a dive, you're doing it wrong.

And for best effect of the flap shouldn't one be using manual trim opposed to combat trim and have them extended prior to the dive?

You're not using them correctly.  The P-38L dive flaps work in game as they did in real life, the problem is that players deploy them either too early (when speeds don't require the flaps) or deploy them too late in the dive thinking that deploying them will automatically make the P-38 recover. 

It's best to deploy the flaps right before you start your dive or immediately afterwards.  Deploying them in mid-dive reduces the effectiveness of the dive flaps so you want to make sure you deploy them when you begin your dive.  Just a side note...if you find that you need to deploy the dive flaps in a dive, you screwed up.  The P-38 can dive at high speeds without the aid of the dive flaps to recover, you just need to take care and control your speed in the dive, its how the dedicated P-38J drivers dive their Lightnings.  Decrease throttle and use your rudders to help control your speed in a dive.

they are already there.  You can see them deploy in F3 mode on the ground.  Come Wing Up with the 113th Lucky Strikes, a dedicated P38 Squad, we use the P38L in the Attack mode very effectively.  We use the P38 L, J and G for fighter support depending on the mission.  We fly as Knights on Saturday evenings 7:00PM Eastern time zone, in the late War arena.   Vox 113.  CO is Gunston, XO  is Traveler.   Check out the films in our wiki page.  The link is in the signature.   Your invited to wing up for an evening, an hour or just one flight, it’s up to you.

 I have always used the following when I'm locked up in compressibility in a dive.

 1. Turn off the engine.
 2. Use the trim control to induce a pitch up attitude.
 3. Then and only then slowly pull back on the stick.

    Works most of the time if you have enough altitude.
