  • Twin Fuselage Racer

    This is an idea that I've been developing over several years. The idea is to create a modernized unlimited reno racer version of a P-82/F-82 twin fuselage style aircraft.

    * Counter-rotating props are used with super-critical airfoil tips. Super-critical airfoils are also used in the wing and fore-plane. Shockbodies are used on the wings to manage transonic shockwave formation
    * The fore-plane has slightly higher AOA and is located ahead of the center of gravity (this layout provides natural stall recovery as the foreplane will stall first - allowing the main wing, which is behind the center of gravity, to naturally pitch the nose down).
    * The fore-plane also contains elevator controls to assist in pointing the nose. The idea here is to increase hard-turn efficiency (by lifting the nose INTO the turn rather than only pulling the tail away as in a conventional layout - the Europeans use this technique on their fighters (Rafael, Typhoon & Grippin)). In other words, this aircraft is optimized for turn performance as opposed to straight line performance.
    * A boom in-between the two fuselages houses the nose gear - this aircraft has a tricycle landing gear for improved ground handling.
    * Area-ruling has been kept in mid with regard to the placement of the cockpit, radiator scoop, wings etc (something that was unknown during WW2).
    * The port fuselage contains the cockpit, while the starboard fuselage housing an enlarged radiator scoop to handle cooling requirements of both engines - the aircraft can be taxied using the starboard engine only to save fuel.
    * Current testing using X-Plane (using two 3,000 hp merlin V-12s) predicts a top straight line speed of around 520mph, and a sustained 3G turn speed of around 480mph.
    * Virtual testing is still ongoing. Additional stall testing, and aircraft handling test need to be completed...

    Hello Carl,
    this looks really impressive! Enthusiastic man like Paul Allen or so should realize it...

    Maybe alternative with twin boil-off cooled R-3350 ?

        That's likely the minimum intersection drag you can get for a twin boom plane.

          520 MPH wow.

            Cool plane!

            Any notes on the types of stresses you'll be expecting in the sections connecting the two bodies?
            I don't know any numbers but I guess you are trading off the drag of having a center wing section for the weight of beefier spars in the canard and tail?

            Anywho, looks like fun
