Marty_d Posted May 13, 2015 Share Posted May 13, 2015 Can't really see the point of tip tanks on light aircraft. They're not like fighter aircraft that have wings built like brick sh*thouses so they can take the weight of ordnance. Why would you hang a heavy weight at each tip, not to mention the plumbing required, instead of having an extra set of moulded wing tanks closer to the fuse?

facthunter Posted May 13, 2015 Share Posted May 13, 2015 Reduces structural weight. If the fuel is carried in the centre it counts for load and the structure has to be stronger. Jet wings are thin too so hard to have fuel gauges that work well. Nev 2 2 Link to comment Share on other sites More sharing options...

Yenn Posted May 13, 2015 Share Posted May 13, 2015 Seems a bit odd for a jet to have such a big wing. i wonder what speed it is supposed to fly at. Big horiz stab in the jet efflux. I don't think I want to fly it. Link to comment Share on other sites More sharing options...

ben87r Posted May 13, 2015 Share Posted May 13, 2015 There is quite a good article I found on the interweb about how the Cessna 310 402A 421A(?) came about their design. There was a few reasons for the tip tanks that I can't remember but the one I can was that the tanks were designed to separate from the wing in an accident removing some of the fire risk. I'll see if I can find it. Link to comment Share on other sites More sharing options...

Birdseye Posted May 14, 2015 Share Posted May 14, 2015 Wing layout is very reminiscent of the Jet Provost. Link to comment Share on other sites More sharing options...
pylon500 Posted May 14, 2015 Share Posted May 14, 2015 Can't really see the point of tip tanks on light aircraft. As Facthunter said, moving weight outwards from the centre lessens the span-load concentration on the spars. The amount of fuel this would need to carry (don't be surprised if this chews 90+ litres an hour!!) would create too much load, requiring the wings to be stronger (heavier). Big horiz stab in the jet efflux. Actually, thrust line looks to be above the line of the stab, PLUS, with a high mounted engine like that, it would probably have a small amount of 'up' thrust to balance the power / pitch couple, giving more clearance. The only problem I have with the layout is the direct side by side seating. In bigger aircraft (like the Provost), the overall weight of the crew forms a lower percentage of the all up weight, so the difference between 'one up' / 'two up', is less noticeable. As aircraft get smaller, this becomes a bigger problem to the extent that many small (read ultralight) planes need to carry moveable ballast (read dead weight), to stay within their weight and balance range. There seems to be a continual resistance to the concept of staggered, side by side seating yet from a technical point of view, it seems almost better than all other layouts; •Pilot / student has expansive view, •Much wider cockpit than tandem layout, •Aircraft can be narrower than full side by side (aerodynamic improvement), •Instructor can still relate physically / visually with student, •Still only one set of instruments required. So I'm guessing people hope it's going to be in the $250k region, but probably end up more like $350k finished. Link to comment Share on other sites More sharing options...
Guest Howard Hughes Posted May 14, 2015 Share Posted May 14, 2015 So I'm guessing people hope it's going to be in the $250k region, but probably end up more like $350k finished. If it's to be used as a military trainer I would expect more like$2.5 mill, you might get the unpressurised version for just over a mill! Link to comment Share on other sites More sharing options...

Birdseye Posted May 14, 2015 Share Posted May 14, 2015 Airframe isn't really going to be an issue, but the motor cost and fuel consumption will be. Link to comment Share on other sites More sharing options...
facthunter Posted May 15, 2015 Share Posted May 15, 2015 It would have to be pressurised to be in any way serious as a Jet trainer (or much else for that matter). THAT will cost and has potential hazards. Note Some Lancairs are pressurised. Nev Link to comment Share on other sites More sharing options...

facthunter Posted May 15, 2015 Share Posted May 15, 2015 Jet engine sounding cool? They can if they are really big with fans that make a beaut noise and you are in the cockpit,well forward from where they sound the best. Otherwise they sound like an overspeeding vaccuum cleaner that turns kero into a bad smell. Nev 1 Link to comment Share on other sites More sharing options...
