Ex-FAAWAFU Posted October 6, 2016 Share Posted October 6, 2016 There is a Wasp at Old Sarum (in the Boscombe Down collection). That's about 3 miles from me, so if you PM me saying exactly what you need, Bill, I'll see what I can do. Negative pitch did indeed come in with the Lynx; you need the semi-rigid head to make it work properly. Saved my bacon in more than one occasion.

JagRigger Posted October 7, 2016 Share Posted October 7, 2016 Found this quite interesting, although the comment at the end that 'some aircraft will be fitted with suction pads instead of wheels' made me smile http://www.britishpathe.com/video/rough-sea-on-land/query/westland+helicopter 1 Link to comment Share on other sites More sharing options...

I see what seems to be a pivoted lamp hanging underneath it is there anything else there I need to capture in styrene too? And is that possible intake down there actually on the box or is it another thing I cant make out from the pictures Thanks to Richellis, Nigel Heath and Julien for those pictures Id still like to see any weapons carrying sytems though Cheers all This is a radar transponder affectionately referred to as the Baked Bean Can. The Wasp comprised of relatively little metal and did not always show up on the ship's radar. When swept by the radar this device would reply with its own ‘chirp’." If you can wait until December, I have just finished the Scout & Wasp Warpaint book. We had hoped it would be ready for Telford, but alas it has been delayed. 3 Link to comment Share on other sites More sharing options...
Ascoteer Posted October 12, 2016 Share Posted October 12, 2016 The Wasp carried spherical luneburg radar reflectors (atop the rear undercarriage legs) to give a better radar return to a shipborne air search (ie primary) radar. IME all RN helos carried a system that would (when switched on) respond to a radar 'paint' with a rapid pulsed response (the 'Chirp'). Ergo it was not strictly a transponder because it didn't respond to a coded interrogation (from a secondary surveillance radar) and it did not 'Sqwawk'. The 'Chirp' served to indicate (especially to an airborne radar such as the Searchwater fitted to Nimrod) that the radar contact was indeed a helo and not a submarine 'snort'. Homing onto a slow moving or hovering helo at 300+ kts while decending through cloud to MOA (min operating altitude) is not good for one's composure (ask me how I know this!). 1 Link to comment Share on other sites More sharing options...
perdu Posted October 12, 2016 Author Share Posted October 12, 2016 Thanks both, I've seen those little spigotty things dangling underneath Sea Kings and the like too I think my nautical Merlin has 'em too ISTR I'll look that up soon I have been touristing down in that London since Sunday but now I'm back and Wasping again Link to comment Share on other sites More sharing options...
Ex-FAAWAFU Posted October 14, 2016 Share Posted October 14, 2016 (edited) Though Debs is right that it isn't strictly a transponder, it is officially called an "I-band transponder", and is indeed a standard fit to all ship-borne RN helos. Debs has already outlined much of how it is used, essentially as an identifier on radar, either to distinguish it from other slow-moving / stationary objects or (most common of all) to help it stand out from radar clutter / weather returns when being radar controlled by a ship or another aircraft - which was the primary attack method for a Wasp torpedo, given the fact that it had no sensors beyond Mk.1 Eyeball. The position underneath the aircraft (nose of a Wasp, tail of Sea King / Lynx) tells that it was aimed largely at ship radars looking up at it, rather than other aircraft radar looking down.

perdu Posted October 17, 2016 Author Share Posted October 17, 2016 (edited) I wondered if that was the I-band dooberry, cheers I think I have found a halfway decent pic of the pylonrackgadget for the type 44 torpedos so I'm making stupidly skinny steady arms at the mo' Edited October 17, 2016 by perdu Link to comment Share on other sites More sharing options...
Colin W Posted October 22, 2016 Share Posted October 22, 2016 Hi Just to add a little different thought, I built a Wasp years ago and was told by an ex RNZN Ground crew that the 'can on a pole thing' was the water sensor for deploying the floatation gear when the aircraft ditched. Thats why it only appears on Wasps with the floatation arms and why its also on the bottom of the Seaking. Cheers Link to comment Share on other sites More sharing options...
71chally Posted October 22, 2016 Share Posted October 22, 2016 It's definitely the I band transponder, on the Sea King it's not on the bottom, its under the aft tail boom Here's a good pic of a Wasp and torp 2 Link to comment Share on other sites More sharing options...
perdu Posted October 23, 2016 Author Share Posted October 23, 2016 (edited) Very good pic, thanks chally Colin I have all the info on the can ta Found a fabulous diagram with all the info on the Wopses gizzitsgadgetsandwotsits, definitely I -band This fab diagram's location? In my Scout collection on the hard drive all the time I think it came from worm when I was Scouting and it shows every unit and panel on (and under) the airframe I have never seen it anywhere else Edited October 23, 2016 by perdu Link to comment Share on other sites More sharing options...

I was informed (back in mid 80's) that the wasp had a grabber. "A vertical harpoon for a last-ditch sticking to the deck" was the description. Being RNZN Leander, I doubt the mess deck residents' association, located under the flight deck, would have been too amused by this being used in anger... 1 Link to comment Share on other sites More sharing options...
71chally Posted October 23, 2016 Share Posted October 23, 2016 (edited) It's late October and it seems Wasps are still about. Here's some detail pics of things I think you've asked about, ie the output shaft/disc brake area, landing and identity light box, box ahead just under nose (TACAN?), and weapons crutch. Note the I band trans' seems a slightly different pattern here.

perdu Posted October 23, 2016 Author Share Posted October 23, 2016 Brilliant pictures chally, funny enough I've been working on the octagonal junction box between the jetpipes where the thermocouple (?) connections join, this evening I must have made three or four scrap ones but I think I'm there now... Your top picture gives me the exact info I need to pop it in place later The others are great too, especially the weapons pylon dooberries, seems it fits exactly how I guessed it must A'hanging off the double butterfly shaped bracketry and the single one behind I think you have filled all the gaps I needed filling thanks Link to comment Share on other sites More sharing options...
71chally Posted October 24, 2016 Share Posted October 24, 2016 No worries and glad they are of use, always suprises me that such a small adapter and apparently frail looking structure can lift a 1000 Ib load. Link to comment Share on other sites More sharing options...
Uncle Dick Posted October 26, 2016 Share Posted October 26, 2016 I think there was also a loud speaker buried in there some where, that could rotate into position and scare the daylights out of any non complying miscreants or give directions/orders as the case may be (obviously loud enough to be heard over the rotor/nimbus racket!)

I was talking to Colin of Freightdog at Telford, who said his Wasp moulds have gone to Czechmaster for production and these are clearly the accessories for the completed kit. I think there will be a Wasp and a Scout eventually. Edited November 16, 2016 by AMB Link to comment Share on other sites More sharing options...

IIRC,"deck grabbing" was done by a mob of handlers scurrying out with four ratchet straps that attached to the tops of the legs and tie down rings on/in the helicopter deck. Sure I heard something about "negative pitch" being applied(is that possible Crisp?)too so as to force the a/c down onto the deck and compress the suspension(once landing on had taken place of course). Here's another one,what about that 70's BBC series "Warship"?,sure that was done on a Leander and they flew their Wasp frequently. https://www.youtube.com/results?search_query=warship+bbc+tv+series Thank you for that Miggers. That one takes me back - to the days when we still had a Navy to reckon with ! The Phoebe ('The Fighting Forty Two'), as someone else said. They had fun with that.
