Wing Wright

WingWright is a design and test bench for people who build things that fly without an engine: paper darts, chuck gliders, foam wings, balsa trainers. You draft an airframe by number instead of by guess, the aerodynamics recalculate while you drag the slider, and then you launch that exact airframe in a flight simulator and watch what your choices did to it.

The design tab gives you four layouts to work in: Classic with a tail, Canard with a foreplane, Flying Wing with a reflexed section, and Tandem with two lifting surfaces. Span, root and tip chord, sweep, dihedral, washout, airfoil, stabiliser size, tail arm, fin area, incidence, fuselage length, nose ballast, material and centre of gravity are all yours to set. Everything downstream updates as you move: wing area, aspect ratio, taper, mean aerodynamic chord and its station, total mass, wing loading, tail volume coefficient, neutral point, static margin, trimmed lift coefficient, parasite and induced drag, best lift-to-drag ratio, best glide speed, minimum sink rate, glide angle and Reynolds number. A plan and side sketch redraws with the centre of gravity and the neutral point shown as two separate dots, so the margin between them is something you can see rather than something you have to imagine.

Then you throw it. The flight tab integrates longitudinal dynamics with a fourth-order Runge-Kutta solver: lift, induced and profile drag, tail moment, pitch damping, stall break, wind and air density by altitude. Choose an overhand throw, a gentle release, a catapult or a high start, set the angle, the speed, the launch height, the head or tail wind, and the trim you want to try. The result comes back as an animated replay at four speeds, four plots you can tap for values at any instant, and a verdict: clean glide, phugoid porpoising, stalled and dropped, nosed in, spiral away or wind carried. Overlay up to five throws on the Test Bench to see what your changes were actually worth.

What you can do:

• Draft airframes across four layouts with sliders and exact numeric entry, every figure recalculated live
• Read a stability verdict from Unstable through Twitchy, Sport and Stable to Sluggish, with one line on how it will behave in the air
• Simulate flights with real launch conditions and replay them frame by frame with tappable charts
• Keep a hangar with eight ready-made airframes, filters by layout and material, personal bests, rename, duplicate and delete
• Compare up to five designs on overlaid glide polars with a verdict on who flies farther and who stays up longer
• Work through build briefs with hard constraints that close themselves the moment a saved model satisfies them
• Study fifteen aerodynamics lessons that pull your own airframe's numbers into the explanation, then test yourself with quizzes
• Track every throw in a logbook with four constructor ranks, a daily streak, sixteen badges and a full statistics panel
• Switch the whole app between metric and imperial units, and export your hangar and log as a text report

An optional assistant can review a design or debrief a flight in more detail. It is opt-in: the app explains what would be sent before the first request, and declining costs you nothing, because every one of those buttons also answers from a rule engine built into the app that reasons from static margin, tail volume, wing loading and aspect ratio. Nothing is disabled, nothing waits on a network.

Your work stays on your device. There is no account, no sign-up, no analytics and no cloud copy: airframes, flights, briefs and notes are files in the app's private container, and deleting the app deletes them.
