Double delta wing design


Apr 18, 2003
Southern Kansas
Other than my intro, this has been my only thread here. I am currently in the design stage of a double delta canard pusher. The original inspiration came from the wing design of the Dyke Delta. But where that plane is a 4-place tractor with the wing in the typical mid-fuselage position, I slid the wing back to the rear of the plane, widened the fuselage and lengthened it to accomodate six people, plus baggage. The canards are truncated in length and angled slightly downward to allow for better visibility. I slid the engine from the front to the rear and smoothed out the lines of the fuselage, blending them into the wing. I'm planning on using the inboard wing strake for fuel storage, similar to the Velocity. I want to use as much composite in the construction as possible. But this is the first time I've tried anything like this. The majority of my work is in sheet metal with the occassional composite repairs. I'm afraid that I've overbuilt the fuselage design as I'm concerned about the wing/fuselage interface will not be strong enough. Any suggestions?
