your later drawing comes to some resemblance to the Long EZ, but jet powered…
however, you have several problems (just to name the few)
– your 1cm thick armour will weigh how much?
– you 0.5cm thick additional armour will weigh how much?
– unless you enemy uses nothing beyond .22 caliber, your aircraft will be shredded by anyone shooting at it
besides, the sheer weight of your “armor” will make it a flying brick, as far as maneuverability goes… well, if you manage to take it off the ground, that is…
any aircraft, big or small uses a “skin” that is waaay thinner and lighter than what you try to do…
there was one that wanted to use a thicker top: the X-32, but with a much more lifting profile… yet, they had trouble, especially to make it take off vertically.
another thing: if you want maneuverability @4-500kph, you’ll need quite large control surfaces, especially to have sufficient authority for take off and landing… once flying about 8-900kph, your stick will be like if it was stuck in concrete… your pilot would need Hulk’s arms to move it…
you NEED hydraulics to move your control surfaces… and there comes more weight… and eats a bit more of your tiny space available inside…
F-22 don’t even stand .22 caliber shots; http://www.youtube.com/watch?v=KaoYz90giTk
The whole side of the plane is around 6 m2 I have around 9m2 that I can cover with 1 cm thick kevlar structure. It would also protect the engine..it is integrated structure…it is only 135 kilos + one fuse former behind radar ( 5 kilos ). The steel plate around the pilot about 120 kilos ( 5 mm steel ). These part would also form the forward fuselage pretty much ( except radar dome )…some overlapping parts migh increase it with 10-20 kilos. Canopy is more problematic If I wanna make it also bullet proof. A-10 has 4 cm thick plexi and Me-109 had even 9 cm thick windshield. F-18 has 17 mm thick plexi ( can take a bird stike at 540 kts ). Rear fuselage may have 6-8 mm thick kevlar and rocket holding spaces might need 3/4 inch thick kevlar or 5 mm steel casing outside and 1 sentimeter kevlar. This same structure also protects the outside of the missile bays and gives needed structural strenght with ribs. The whole wing is a big hollow plate with ribs and spars and attached to fuselage in spars and missile bays with bolts..so the wing comes of when needed. Some attachment points at front and rear. There has to be some access panels too that increase the weight a bit.
Hydraulics might eat some area in the wing for sure. 100 kg less fuel than anticipated. Structural model in 1/5 scale would be interesting. Landing gear design is ready already..and its attachments to fuse and its retraction mechanism. Could it work with compressed air like in R/C models..it would be the litest ?
