advancedboy 5 Report post Posted December 27, 2010 A sketch of Gulfstream Lightweight Cargo plane. The engine surface uses Coanda effect over the wing stampings. Designed for regional airports to carry loads up to 35 metric tons or something like that:) Devoted to John Lear Some minor changes might apply. Bring manufacturing home!

The first couple things that jump out are the size of the body in relation to the wings. body seems big for the surface area of the wings. The motor on the left wing(as you look at the picture) appears to be ovalized vertically and the other motor appears to be ovalized the other direction.

advancedboy 5 Report post Posted January 23, 2011 Bell Twin-x concept. Nex gen chopper for Bell. It has a new type of fenestron. it is twin hubless fenestron with 2 counterrotating propellers. The propeller is a big bearing with gearing on outer rim. Driveshaft is attached to the propeller gearing. As both propellers are rotating opposite ways, the propeller blades are attached at opposite angles on each propeller to create equal thrust in the same direction. Twin fenestron is harder to destroy by shotguns, etc, and if a blade is missing the balance is not lost so dramatically, as the blades are distrbuted in 2 propellers and the main volume of mass is on outer edge of the bearing.

Constantin 2 Report post Posted February 25, 2011 Interesting concept. I like the shading and colors you choose. For the "bad" side, I see the perspective differs on parts of the aircraft. Look at the two engines one is stretched vertically and the other a bit horizontally. Other than this, good work! Share this post Link to post Share on other sites

advancedboy 5 Report post Posted March 2, 2011 This is the next generation of stealth bomber. It has a new principle of pitch control. It has no rudder,but it uses front wing edge drag to achieve steering.The wing edge is electrostatically charged, which reduces drag by about 40 per cent. The steering( yaw control) is achieved by switching electrstatic charging off in one of the wings, thus increasing drag, which will allow the aircraft to change direction. This is just a sketch, I will post soon another sketch , which will have a rudder , and could be built to check this type of steering using rudders as back up for the technology demonstrator. The aircraft uses negative delta wing in orger to have a maximum length available for electrostatic charging up front. What do you think? Share this post Link to post Share on other sites
advancedboy 5 Report post Posted March 4, 2011 This is another view of Boeing Cargox regional cargo plane. It differs from front view as I tried to change some details. Basically a technological innovation is the aileron behind the engines . It is directly where the exhaust of engine is, when the airplane is changing pitch, the aileron not only changes the air stream direction on the wing , but it also changes the direction of exhaust in the engines. As it basically uses the same aeleron that is on the wing , but is prolonged to go along the engine exhaust, this would allow to save weight and installation of additional motors and actuators.
