In aerodynamics, wing loading is the total weight of an aircraft divided by the area of its wing. The stalling speed of an aircraft in straight, level flight is partly determined by its wing loading. An aircraft with a low wing loading has a larger wing area relative to its mass, as compared to an aircraft with a high wing loading.
A loading device for simulating a telescoping wing transmission mechanism
This invention discloses a loading device for simulating a telescopic wing transmission mechanism, comprising a telescopic wing motion simulation mechanism and a telescopic wing loading mechanism. The telescopic wing motion simulation mechanism includes a fixed base, a motor, a movable wing, and a linear bearing. The fixed base and the linear bearing are fixedly installed on a base platform. The motor is installed on the fixed base and drives the movable wing through a transmission mechanism. The movable wing is slidably installed on the linear bearing. The motor drives the movable wing to perform reciprocating linear motion along the linear bearing to simulate the extension and retraction process of the wing. The telescopic wing loading mechanism includes two sets of loading units respectively arranged on the extension side and the retraction side of the movable wing's movement stroke. Each set of loading units includes a fixed frame, a tray-pulley system, a hoist, and a load. The fixed frame is installed on the base platform, and the load is placed on the tray of the tray-pulley system. The tray-pulley system is connected to the movable wing through a steel cable.

High-altitude pseudo satellite control
A High Altitude Pseudo Satellite (HAPS) aircraft is disclosed for maintaining the span-wise shape of the wing and maintaining total bending and torsion loads. The aircraft including at least one aeroelastic span loaded fixed wing having an aspect ratio greater than 15 and wing loading less than 6 kg / m2, the wing having a plurality of spoilers distributed across the span of the wing and each spoiler being chordwise located adjacent the center of pressure of the wing. The HAPS aircraft further includes a control system for controlling the spoilers, and sensors which determine the amount of lift at points or regions along the wing span, the pitch and roll at points or regions along the wing span, the bending and torsional strain at points or regions along the wing span, or the absolute speed and roll and pitch angle of the wing.
