Airships
Envelope membrane loads, frames, hardpoints, fins, and pressurized shell response.
Section 4 / aerospace applications
From airship envelopes to everyday aircraft structural analysis.
The original research challenge was demanding: large flexible shells, pressure-stabilized forms, fabric and membrane behavior, attachment loads, and geometry-dependent stiffness. That background translates naturally to rapid aerospace stress calculations.
Hot-air balloons
Fabric stress, gore geometry, pressure, thermal effects, suspension, and load introduction.
Aircraft structures
Panels, beams, fittings, frames, skins, stiffeners, pressure shells, and local details.
Surface equilibrium: ∇s · N + p n + q = 0
Combined loads: (Nx/Nx,allow)a + (Nxy/Nxy,allow)b ≤ 1
Panel / aircraft fuselage stresses
Aircraft fuselage stresses — a typical aircraft fuselage case study
A pressurized fuselage is a thin-walled cylinder: cabin differential pressure ΔP drives circumferential (hoop) and longitudinal skin stress, local stress concentrations around cutouts such as windows, and small out-of-plane deflections between frames and stringers — worked with closed-form elasticity and shell theory (the Kirsch solution for a loaded hole, the classical cylindrical-shell edge-bending solution for frame restraint) rather than a commercial finite element solver, so every number traces back to a named equation.
Panel / flight comfort & gust response
Flight comfort & gust response
Turbulence discomfort isn't random — it comes from a specific, well-established aircraft-design equation: the discrete-gust incremental load factor (the “Pratt formula,” the basis of FAR/CS-25 §25.341 gust design loads). A vertical gust changes the wing's angle of attack, changing lift, and the aircraft's own inertia only partially damps the resulting vertical acceleration — that acceleration is what passengers feel as a jolt.
Panel / aircraft components
Aircraft, spacecraft & defense components
Dedicated analysis coverage for individual aircraft, spacecraft, and defense-system components is being added to this section over time. Each area below will become its own detailed page, following the same pattern as the tools in Stress Analysis Tools.
