"saw-wing" Motorized Glider

Recommended Posts

Guest retrospec

just a concept... in my opinion, gliders have always been one of the best looking types of machines in the aircraft industry. This glider is inspired by the shapes of a saw wing or other swallow birds and is able to use small motored propellers to assist, prolong or replace the gliding. I know the solar panels are cliche', but hey it would be a waste not to have them on such a lightweight plane with a large surface area on the gliding wings right? : )

I don't mind if it is critical or not, I just want to know you guy's opinions on the design, so I can further tweak it.

Is there any difference of aerodynamics if you make the center wing as a V-shaped rather that straight ones? Just to be seen more modern and sleek in my thought..

yes, the v-shaped wings or swept wings will be quite bad for gliding, but the straight wings will make the plane slower, it's a trade off I believe.

tail surface area looks a bit small to me. Also I cant see that the canard foreplanes would be of any aerodynamic advantage.

Retrospec,

I like the look, very stylin.

 

Pretty sure that a swallow uses its tail as a 'control surface' for turning. In a plane, you may want more aero stability, your current design will have trouble with stability in the yaw direction. Next, your wings are long and so should not end in a cut-off, migrate the curved tips of the "canard fore-planes" to the wings, this will reduce wing-tip vortexes and drag. Take a look at newer jet wing tips, for example, a bombardier challenger 605. Not sure how the wing tip will interact with the props, maybe look for something that already has that design.

 

Regards,
