Cees Broere Posted February 25, 2022 Share Posted February 25, 2022 Hi all, As I am already working on my second 1/32 British Toom, a RN FG-1, I want the aircraft to be with extended nosewheelleg and deployed leading edge slats. But looking at photos I cannot see how the slats were hinged or what the structure looks like. Does anyone have any info on this? Thanks in advance.

f111guru Posted February 25, 2022 Share Posted February 25, 2022 Hello, The phantoms leading edge slats are hinged at the bottom. Not having my aux drive hooked up to get a reference photo for you.

Robertone139 Posted February 25, 2022 Share Posted February 25, 2022 All Brit Phantoms had droopable flaps on the wing leading edge. Only Phantoms with slats were F-4E (late), F-4G and F-4S. 4 Link to comment Share on other sites More sharing options...
71chally Posted February 25, 2022 Share Posted February 25, 2022 Not forgetting that the inboard leading edge flap panels remained fixed on FG.1 and FGR.2s. 2 Link to comment Share on other sites More sharing options...
f111guru Posted February 25, 2022 Share Posted February 25, 2022 @Cees BroereFound these on my phantom reference drive and for visual acuity. The first and second are of an F-4D. The underside shows the outline of the hinge on the wing tip and inboard leading edge.. Broadside view for the full down angle Royal Navy FG-1 broadside lead on from the front. Hope this helps with your project. Noted above photo shows the inboard slat is locked in the up position. The image of F-4D 66-7707 shows the inboard slats are down.

Jabba Posted February 26, 2022 Share Posted February 26, 2022 At least on FGR2s which I worked on at RAF St Athan the inboard flap was bolted up, had no actuator and so could not move at all. I think that the FG1 would be the same. 1 Link to comment Share on other sites More sharing options...
Duncan B Posted February 27, 2022 Share Posted February 27, 2022 The leading edge flaps were hinged from the bottom. It was called a piano hinge and consisted of two rows of interlocking square tabs along the whole length of the underside face of the flap, one set on the flaps and one set on the wing or opposite face. They were lined up and then a long wire pin was inserted through the whole lot. It wasn't just the flaps that had them, the large engine doors* on the rear fuselage had them too as did most of the other hinged doors (not the speed brakes though) if I remember correctly. The inner most leading edge door on the FG1 and FGR2 were fixed (i.e. not part of the flying controls) but did hinge down on piano hinges for access to the BLC pipework. *McDD referred to all the removal panels as doors Duncan B Link to comment Share on other sites More sharing options...
FG2Si Posted February 27, 2022 Share Posted February 27, 2022 (edited) I don't know enough about the British Phantoms but if they had the hard wing Wolfpack Designs made a dropped wing resin conversion for the Tamiya F-4EJ kit. I have one around somewhere I could get pics of if that helps. Carl Edited February 27, 2022 by FG2Si Link to comment Share on other sites More sharing options...
Sabrejet Posted February 27, 2022 Share Posted February 27, 2022 There I was thinking we had an interesting post on post-War Corsairs! Any chance of correcting the title? 1 Link to comment Share on other sites More sharing options...

71chally Posted February 28, 2022 Share Posted February 28, 2022 AVQ-11 Pave Sword I would say. 1 Link to comment Share on other sites More sharing options...

Cheers, Andre @Hook and @71chally, It's either a Pave Mover AN/APY-7 or a Pave Sword AN/AVQ-11. A year before my time and never saw a pave anything pod at RTAFB Udorn in 1972. All our lasing was done from the F-4 aircraft out of RTAFB Ubon. All the images for the most part came from the F-4 Phantom group once housed in Yahoo Groups.

Hook Posted February 28, 2022 Share Posted February 28, 2022 Thanks! Whatever it is, it's Pave Frigging Huge. 😎 Cheers, Andre 1 Link to comment Share on other sites More sharing options...
Troffa Posted February 28, 2022 Share Posted February 28, 2022 Some great shots of Phantom BLC ducts on this chap's twitter feed. This is a German aircraft, but configuration looks the same as the British ones I ran my hands along during every see-off I performed in the distant late 1980's.

Robertone139 Posted March 1, 2022 Share Posted March 1, 2022 Starting with the F-4J (and possibly retrofitted to the B under the guise of N variants) the boundary layer blowing system implied that the inner section of leading edge flaps would be locked in the up position. The BLC system was a US NAVY thing and subsequently applied to all naval variants, including the Spey powered ones. Link to comment Share on other sites More sharing options...

Ben Brown Posted March 2, 2022 Share Posted March 2, 2022 @Robertone139, great pics of the leading edge flaps! The BLC was fitted to all "hard wing" F-4s, both USN and USAF. It was deleted on F-4s fitted with leading edge slats. The inboard section of the leading edge flaps was fixed on the F-4J and F-4N in an attempt to improve low speed pitch control, IIRC. According to Tommy Thomason's Tailhook Topics blog, it was brought back on the first few F-4Js that were modified to F-4S, but was soon deleted again.

I believe it was an infra-red sensor possibly boresighted with the Lead Computing Optical Sight for night-time targeting and ranging for a dumb bomb attack in Dive Toss mode. The paperwork on the thing is still classified fifty years later. IIRC the inboard LE blown flaps were fixed on Block 28 Navy jets and up (slotted stabilator introduced at the same time). This airframe change was retrofitted to earlier F-4Bs, and standard on F-4Js on which the F-4K was based. Tony 1 Link to comment Share on other sites More sharing options...
