This is a WW1 BE2 operated by RAF.

This is a V1 rocket recovered from London attacks.. Note the prominent pulsejet engine sitting on top of the fuselage.

Also note how the elevater is hinged.

This is a WW2, german made, single man submarine. This was recovered north of UK. The man who drove the sub died due to carbon-mono-oxide poisioning.. obviously, the smoke has seeped in the cabin and killed him.

Note that this sub was a very dangerous weapon. See the size of the tropedo on the side. Enough to tamper the steel armour of a battleship.

In the last pic, note the pull-pull mechanism installed in the control surfaces of the sub

No introduction required for this... here is the little boy replica.

This is how it would look inside an A6M5 Zero figher. Note that the pilot seat is removed.

The Salamander He-162. Could not get a clean shot of this one...

This is a naval mine capable of shattering battleship's armour plates. The moment a ship touches its horns it would explode... again a brain chid of german innovation!

Various other naval shells...

The deceptive Enigma machine... used by the germans in WW2 for naval communications.

The P51...

Note the boost tabs in the elevator.

The spitfire..

Fw-190

The SOP Camel.. WW1 fighter

The most feared german weapon - The V2 rocket..

Wow!!
those are very nice planes... wish i could own them 

Hi Ismail,

Nice pictures man.. Where is this museum in london ?

The way these brits maintain their antiques should be aplauded and i hope india learns the importance of maintaining antique things...

Do visit some of the forts & see the pictures and anitques maintained for centuries....Do not miss going to a town called as bathspa & woodstock and oh yeah do visit oxford..superbb is the word..

I love brits  especially brit gurls..

Cheers

Ya. Most were looted from other countries decades ago. So obviously they do want to preserve their loot.

Ismail,
Would that not be trim tab rather than boost tab?

trim tab - that's we call it in normal light aircraft language

maybe they called it a boost tab in those days ?

(posted without googling )

I "guess" boost tabs and trim tabs are different. My guesses are:

Trim tab: The tab moves only when the pilot uses the trim function. Further, it does not have any additional movement when the larger control surface moves. It is just like a plank struck to the control surface and its angle could be varied by the trim function only.

Boost tabs: Its looks very similar to the Trim tab but it provides additional movement when the larger control surface moves, there by generating more force on the control surface. It should be noted that the servo torque could be lesser than what is normally required if there is no boost tab. So, in practical terms you could use a lower torque servo on a considerably larger model. 

One interesting thing is the boost tab would move in opposite direction w.r.t the main control surface it is attached to. Flying giants forum has good refereces on boost tabs. Too lazy to dig in to that.

There was a nice webpage explaining the technical details on boost tabs but it seem to have vanished from geocities. I will post it if I could find it.

On the other side, I found that IAF Museum at Delhi in shabby condition.  Sikorsky helicopter kept in open and rotors at the mercy of supporting poles.  Someone  has painted a beautiful B-24 Liberator in silver paint, even windows and cockpit windscreens are paint covered and parked under open skies in all weather conditions. Side door of C-113 about fall.  couple of others also parked in open at the mercy of weather god.  Most of the exhibits are in one hangar, too close to each other and looks very congested.   Need more space for exhibits and it could have been better managed to provide better look, shelter and life to displays.

trim tabs also move in the opposite direction to intended
control surface deflection - the idea being that trim tab
deflection and the airstream would give an opposite
control surface deflection without constant input from the pilot -
thus trimming the aircraft against undesirable flight path.

"On the other side, I found that IAF Museum at Delhi in shabby condition."

I crawled into the empty engine bay of the Ohka Piloted Bomb (a very rare specimen anywhere in the world) to retrieve an empty packet of gutka. Convinced the curator to get the cockpit of the Spit and the Hurri cleaned so that I could sit inside and take snaps. He was kind enough to entertain my request.

Cheers!

Then both Boost tabs and trim tabs refer the same!
