evening chaps, Im currently working on a project that requires light weight pressure vessels. Im stuck on how to calculate minimum wall thickness for the vessels in different materials for a given pressure. I.e how much bigger would they have to be if they were steel over aluminium etc...
evening all, im hoping some here can help. witout the use of cad for the moment im trying to calculate what happens to the air flow in a rifled barrell with regards to the rifling. i.e does the air closest to the wall corkscrew with the rifling, does the entire volume corkscrew? do the...
im not sure on the words to use here as ive never done anything like this before so i dont know what the terms are.
imagine a lattice beam but instead of attaching the ends of the cross pieces to the beams frame you attach them to eachother by means of bearings so when you close the bottom to...
evening all,
just wondering how do i go about working out the vertical load on a lattice type beam with ends facing vertically i.e
\/
..
/\
with the dots being the hinge pins.
i cant figure out how to work out the load on each beam section and each pin joint at its maximum load and at...
does anyone know if one of these exists? we use a lot of button headed allen key bolts at work from m3 to m8 sizes. the trouble is there used around a lot of delicate equiptment and tight conditions mean using balldrivers at awkward angles. due to these conditions when a head rounds we cant...
very interesting reading on the ekranoplane!
obviously standard hovercraft are a longway off of these speeds in the same way that standard passenger cars are.
one interesting point i hadnt considered before is that y placing the ekranolanes wings behind the engines they get all that extra air...
cant find any info on the shockwave rider?
what i was thinking was an aerodynamicall outer hull with a leading edge lower than the hovercraft skirts kinda like the body sits over a spaceframed car. I like the idea of allowing high speed air under the front deliberately after all why pump it in...
the air wouldnt need to be going supersonic though would it? because the fans and the air pocket are moving at that speed??
just wondering what the waves travelling under the craft would do tthe pocket of air? i.e a high pressure wave moving under would case a verticall lift on the vehicle like...
Evening all, not sure if this is going in the right area but you may be able to help me.
For my own interest im wondering that the effects of supersonic waves would be on hovercraft travelling above the speed of sound? Putting aside other issues such as weight and skirt wear etc how would the...
mclaren have supplied me with 30bar injectors before- If you need small bodys and high flow then higher pressures maybe the only way to go?!
If not give them a ring anyway theyve always been very helpfull to me and i believe they will do some custom work for the right bank account!
nicator- that pipeing from lindsay racing could work the other way round, ramming air through the inside of the pipe to cool engine coolant, could be a good way to flow some of the stagnant air from under the hood to the rear of the car aswell especially with a rear rad setup
As a shoot off from the original thread, would it be possible to have ports like waterways/ or original waterways around the inlet ports on the head connected to a co2 system to supercool the inlet and or the block for a short time?
id be worried about the sudden heat changes causing engine...
frames being made at the minute with the final bracing for the engine to be sorted once the final engine dimensions are sorted.
Aerodynamics dont really interest me and this is after a project so i think il hand the green stuff over to a proffesional there and let them sort nose lift at...
rb1957- kind of like a jet engine only take the compressor away and attach the exhaust turbine to the gbox.
From my little experience with jet engines and what ive found on rockets, as a propulsion system they are pretty ineffecient as they have no solid mechanical connection with the surface...
haha no its not for school, i apologise if it came across that way. Im a bit to proud for letting other people in on subjects and tend to keep things very vague-a bad habit i must get rid of.
The turbines will drive 4 axles underload via speed reduction gearboxes with a maximum axle speed of...
hi there, from my experience with ballistics you going to find that the rocket will follow its 'parabolic' curve BUT as the centre of mass changes the point along the rocket that is following the curve directly will change (like the pivot point of the rocket if you like). Some thing tells me...
First off hi all and great forums, ive been skulking in the background learning a hell of a lot for a while now and finally decided to register.
I hope someone on here will be able to lend an ear to the problems im currently facing.
although i have no previous experience in the aerospace...
