belfast boyo Posted December 27, 2016 Share Posted December 27, 2016 I am going to start something a little different,a jet powered truck!Using either of these.. Or this,I have about 15 rigs to choose from depending on spec/wheelbase! Using an engine from a Harrier,it will be a slow build so dont hold your breath - comments and tips are more than welcome.

Warren D Posted December 27, 2016 Share Posted December 27, 2016 Every jet truck I've seen has been low to the ground and long wheelbase for stability. Quote Link to comment Share on other sites More sharing options...

426-Hemi Posted December 27, 2016 Share Posted December 27, 2016 I'd go with the International..... Not sure how a Scania would be Jet powered... -Being a COE! Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted December 27, 2016 Share Posted December 27, 2016 ... Not sure how a Scania would be Jet powered... -Being a COE! Simple. No matter WHAT kind of cab the thing has, the jet engine gets mounted behind it, where the thrust-producing exhaust has a clear shot out. The Harrier he's sourcing the engine from produces its power as exhaust thrust, not a turbine-shaft-takeoff, so there's no necessity to retain any of the original drivetrain or engine-placement.

426-Hemi Posted December 27, 2016 Share Posted December 27, 2016 This is true Bill,BUT I'm merely saying for "looks" sake........ I think the International look better then the Scania jet-powered....... Quote Link to comment Share on other sites More sharing options...
belfast boyo Posted December 28, 2016 Author Share Posted December 28, 2016 Got the basic engine assembled,there is more to add but give it time, The chassis is partly assembled too,I have decided that it is four wheeler and therefore the rear axle has been moved to the very back of the chassis.I might cut the jet down at the red line and have a single large 'exhaust port thingy- very technnical here....' Not sure on the cab yet so this is just a mock up.... Quote Link to comment Share on other sites More sharing options...
kilrathy10 Posted December 28, 2016 Share Posted December 28, 2016 Now, this is interesting.....I'll be watching this one...... Quote Link to comment Share on other sites More sharing options...
Flynlo Posted December 29, 2016 Share Posted December 29, 2016 (edited) Cool idea. I am looking forward to this build! Random thoughts and useless trivia: You could add scoops to the window cutouts in the sleeper and duct these into the engine inlet. Installed with the original nozzle configuration, the front nozzles could be pointed slightly "up" at speed to help offset aerodynamic lift and keep the front end planted. All 4 vectored up and forward for braking at the end of a run Thrust from the front nozzles of the R.R.Pegasus is made up of bleed air from the fan section at the front of the engine so it is much cooler air than the rear pair whos thrust is generated by combustion gasses, Edited December 29, 2016 by Flynlo Quote Link to comment Share on other sites More sharing options...
belfast boyo Posted December 29, 2016 Author Share Posted December 29, 2016 Thanks Tim,will see. It is a Mobius kit repopped by Revell,more on the cab later.. The engine has had it's rear vents cut away and am doing the fronts,but....my arthritis kicked in and my hand was just cramping and dammed useless.... Back to the cab,the sleeper portion had been lopped off and the front glued on - no need for engine access here....Thinking about styling perhaps the rear axle could come forward a degree? Wheelwise I have a set of genuine alloy rims from Hiroboy,going to see if the kit wheels can be adapted to use them.. Quote Link to comment Share on other sites More sharing options...
DRIPTROIT 71 Posted December 29, 2016 Share Posted December 29, 2016 Cool project!! I'm looking forward to seeing more!! Quote Link to comment Share on other sites More sharing options...
belfast boyo Posted December 31, 2016 Author Share Posted December 31, 2016 First of all here are the rest of the engine components. Here are the wheel parts,the wheel centres have been sprayed with black primer. She is on her wheels for the first time,found some checker plate that may be used....

belfast boyo Posted January 1, 2017 Author Share Posted January 1, 2017 Started on the engine mounts/cradle,it is sprayed flat black because it is red plastic and I dont want it to bleed through! Working on the engine too,doing a few electric bits and pipework plus adding a couple of mini thrusters from I think....a DC9. The business end of the engine... The kit that the engines were half inched from,it was a thing from last year that went wrong decal and paintwise... Quote Link to comment Share on other sites More sharing options...
JerseyRed Posted January 1, 2017 Share Posted January 1, 2017 Another example of the great imagination around here. Very cool stuff! Quote Link to comment Share on other sites More sharing options...
Dave Ambrose Posted January 1, 2017 Share Posted January 1, 2017 This looks like a fun project. That Harrier engine is an odd one. You'll need the side vents to direct the bypass outlets to the rear. I'd also move the engine to the rear so you have plenty of air intake space. Most of the ground-based turbines I've seen also have screen domes over the intakes to exclude debris.

belfast boyo Posted January 2, 2017 Author Share Posted January 2, 2017 Thanks Dave. Got the engine sprayed today,a combination of magnesium,light burnt metal,jet exhaust with the turbine blades in stainless steel.Made a tail pipe and added two extra mini motors to it.

gatorincebu Posted January 2, 2017 Share Posted January 2, 2017 Hmmm veddy interesting! desk top engineering ! Will be watching to see how this progresses.Nice paint job on the jet engine. Be Well Gator Quote Link to comment Share on other sites More sharing options...
belfast boyo Posted January 3, 2017 Author Share Posted January 3, 2017 Thanks Marc. Starting on the bodywork as I want it to be streamlined. Going to have a bit of ''whatiffery'' here,so the cab and bodywork are fibreglass and tilt up hotrod style! It is only a mockup here so we shall see..

cowboy rich Posted January 3, 2017 Share Posted January 3, 2017 I really like your build and agree with using the prostar kit, one question however what is the purpose of a tilt cab on a jet truck? Not a criticism just curious. Enjoying watching it come along. Quote Link to comment Share on other sites More sharing options...

I had to section the floor in order to fit the side skirts,just a case of plating it to refit. Quote Link to comment Share on other sites More sharing options...
72 Charger Posted January 4, 2017 Share Posted January 4, 2017 Your going to need some strong wheelie bars for the rear of that. good progress Quote Link to comment Share on other sites More sharing options...
belfast boyo Posted January 4, 2017 Author Share Posted January 4, 2017 Been thinking about this re colours and am thinking jag puple/ or corvette yellllaghhhhhhhhh or both.. instead....Lots of zero paint colours to choose from.. Quote Link to comment Share on other sites More sharing options...
belfast boyo Posted January 5, 2017 Author Share Posted January 5, 2017 Decided on the wheel colour and it is Ford daytona yellow,my dad has a mk3 Cortina in his colour and it was rather nice. Quote Link to comment Share on other sites More sharing options...
belfast boyo Posted January 6, 2017 Author Share Posted January 6, 2017 Someone mentioned to me wheelie bars,well my take on his is a h-d slide plate. Will probably fit a pair of hydraulic dampers here to keep the plate downwards in use.. Quote Link to comment Share on other sites More sharing options...
TarheelRick Posted January 6, 2017 Share Posted January 6, 2017 Since this is a jet-powered machine the power does not go to the rear axle, therefore there should be no need for wheelie bars. Wheelie bars only purpose is to counteract the tendency for a car to rotate around the rear axles under acceleration. This is going to be an outstanding build. I have an Allison powered Falcon Ranchero in the planning stages. BTW are you going to fabricate some form of scoop around the intake? Where it is setting now, the engine would suck the back of the cab loose; actually the engine would probably starve for air. Quote Link to comment Share on other sites More sharing options...
