Scout Helicpoter Information Needed.....
Hi everyone,
We are currently doing a final year project on this helicoter and more specifically a landing gear design. Anyway im trying to get hold of C of G positions for this particular helicopter and any other data such as weights and limitations.
Would be much appreciated if anyone could point me in the right direction to finding such data. Been having a look on google, but to no avail.
Many Thanks
Dan

Fairly sure that there is a militray helicopter 'group' based at Thruxton airfield, Hampshire and that they have a Scout. I don't have a number but a call to the airfield should point you in the right direction.
Aside from that have you tried asking the Army Air Corp? Sure thay must have a few dusty operating handbooks lying in a cupboard

Isn't ETPS still operating one, they may be able to help with manuals, perf data, etc if you phone and grovel. (Best bet might be to phone the Boscombe Down tech library / information centre).
I am proud owner of a Scout hover performance slide rule, unfortunately Simon Newman at Southampton University has it at the moment. If you happen to be at Southampton (or know him, you've probably read some of his textbooks at some point), go and ask him if you can borrow it. If you aren't and it might be useful please let me know and I'll see if I can recover it, you'd be welcome to borrow so long as I get it back.
If you're looking at undercarriage structural performance, it's for fixed wings, but you could do worse than go to the British Microlight Aicraft Association's website at www.bmaa.org and download Technical Information Leaflet No. 016; it contains quite a lot of information on how to meet undercarriage structural requirements. Also go to the Def-Stan website (should be linked from the Sticky on tech-log) and look into Def.Stan 00-970 part 2; somewhere in there should be the military helicopter undercarriage requirements - Def-Stans are generally very good with guidance material which should help you through it.
Finally, don't forget to reference all these documents in your report - gets you serious brownie points from the assessors. (I know, I am one).

Used to have Scouts based at my airfield.
Pilots always said the (skid) undercarriage was designed so that if you did a heavy landing, the skids would 'give' without damaging the airframe; you could literally jack it up, fit a new set of skids, and fly again!! They also said there was NO WAY you could do that with the Gazelle!

The cross-tube under the rear of the fuselage was more susceptible to giving up before the skids. We had one quit in 85 in FI, due to corrosion inside the tube.
Nice machine, the old Queen of the Skies, but I preferred poling around in the Chicken Leg, even with the likes of Mighty Gem.

Figures for WASP won't be far out if you don't get the Scout figures
MAUW 5500lb
F/A Cof G range 3.75'' fwd of datum to 5.5'' aft of datum
Lateral Cof G range 3'' port of datum to 5.75 stbd of datum
IIRC datum plate was on cabin floor just in front of the rear bulkhead, it's been a few years...
Hope it helps

Thank you very much for the replies and most of them have been of great use to me and the group. I wondered weather anyone knows off hand how much the fuel tank can hold?
I know it is also a very specific question, but i dont suppose anyone knows how much the skids weigh in total? Im probarbly going to have to refer to Westland themselves for that information, but it is worth a try!
Many Thanks
Dan

As for the weight of the skids.
What Next?!!Remembering back to when we used to help the BATs do things like skid changes, I\'d hazard a guess at around, not much more than 4-5kgs each, (just the skid).
Most a/c flew with the ground handling wheels attached, if that makes a difference.
