MODEL 777

WINGS

I love the sleekness of the wings and am fascinated by the way the control surfaces (flaps, slats, ailerons, and spoilers) seamlessly extend and retract. My goal is to make a fully-functional set that operates exactly as the real plane’s would.

Due to the sheer complexity of this goal, I’ve broken the wings down into various sub-systems and have been creating test pieces for each in order to verify the integrity of my designs. I’ve also had to come up with new production processes to enable the level of precision that will be required in the final product. This includes building a wingbox jig to hold the wing in place during construction, and multiple molds to help me accurately form the paper that will become the outer skin.

The wings remain in progress and will be the single most complex part of the model, with thousands of individual parts.

WING WIREFRAME

AILERON

The ailerons are located on the outermost trailing edges of the wings and help steer the plane at low speeds.

FLAPERON

The flaperons are located between the inner and outer flaps on the trailing edge of the wing. As their name suggests, they are both a flap and an aileron, and assist in increasing lift and steering the plane at higher speeds.

SLATS

The slats are located along the entire length of the leading edge of the wing, and help produce extra lift for takeoff and landing.

WING-BODY FAIRING

The wing-body fairing smooths the junction of the wings and the fuselage to provide a more aerodynamic shape, and creates enough space in the belly to allow the landing gear to fully retract.

WHAT’S LEFT TO DESIGN AND BUILD?

The inboard and outboard flaps, the spoilers, and, most importantly, the assembly strategy/process itself. Stay tuned for updates!
