Jack If you are after lift at very high AoA go for a delta planform they can be symetrical.
You will get vortex lift at high AoA and they are
typically good up to 25degress AoA
The bigger the hole the better the air through it is very true but the idea with multi louver is that the air flow over them causes a reduction in pressure helping to suck the warm air out. (Or they are simply cosmetic). The best example of this is on Le Mans cars, on the front wings.
The...
Hi Paul,
Now you have mentioned what you have mentiod I see that you have thought about what you are doing! quite condiderably!
what I ment was if you have a hole at the front of the car with a pipe to the back then you will not reach stagnation pressure as (as you are probably aware!)...
Hi, sorry I didnt make mayself very clear because i wanted you to think about the problem some more. i278 explained what i meant though. If you want to introduce a high pressure jet the only place you will get a high pressure is from the (engine)exhausts. and obviously when you corner you lift...
If you put a tube from the nose of the car to the rear of the car then the nose of the car will be at 1 atmosphere not at a higher stagnation pressure. i think you might want to rethink you theory a little more...
Well read butelja!
The picture in the the link is of an artist's impression. A WIG of this size would need to use roll in order to turn. I wouldn't fancy being the pilot, regardless of how efficient the wing may be!
All the pictures I have seen of 'real' WIG's all have no anhedral or dihedral...
If you look on the site more closely you will see another thread about ground affect a/c
thread1-33828 suggest if you are that interested you have a look there.
The configuration of the tailplane is not totally unique. several aircraft have dihedral configuration elevators and no vertical fin.
I only had a quick look at the diagrams and it occurs to me that it would be difficult to mount actuators as to move the control surfaces. I think it may be...
That is not an airframe issue that is a thrust issue and is dependant on the thrust generated by the engines without reheat.
And they both had the same engines! (that is to say that the P&W engine was better than the GE one!)
No, i am sorry i am neither male or female. I am just a rug used to clean the soles of shoes (or boots, its all the same to me!) and as such i have no sexuality... oh well
Glad we sorted that out!
there is an equation to determin the flow of air from a propeller but unfortunatly i dont remember it! any good book on aerodynamics should have the theory in and equations to work out the the airflow. or have a look at this and see what you think...
thread2-29477...
yshij,
it is clear that all aircraft produce lift regardless of their speed and that in doing so create drag. So I dont see why you say it is not properly defined.
In the transonic region shock drag jumps very high but as you go through mach 2 this drops to a level slightly higher than for...
Pitot, I am sorry if I have upset you. I was not meaning to. But the cost of running a wind tunnel of the size required for the subject you wish to test would not be good. The tunnel would have to be huge (assuming it is a closed loop) Like towbar says because of the height which go-karts run at...
