A Wing-by-Wing Approach for Biplane Static Longitudinal Stability and Control Analysis
SAE Technical Paper Series, 2008<div class="htmlview paragraph">This paper presents a theoretical model for the analysis of the longitudinal static stability and control of biplane aircrafts that take into account some effects neglected by the classical approach based on the concept of an aerodynamically equivalent monoplane.

A New Method of Strengthening Longitudinal Static Stability of Airship in Ascent
Applied Mechanics and Materials, 2014To improve the controllability and maneuverability, airship is usually designed as static instability. But the airship is vulnerable to sudden wind interference in its ascent, resulting in divergent pitching motion. A new aerodynamic shape was put forward which added a inflatable aerodynamic-lift wing at backward of the airship hull. With the method of

Abstract Hypersonic waveriders have the potential to significantly reduce travel times on long haul civilian transport routes. The design of hypersonic aircraft is heavily influenced by the aerodynamic efficiency at the cruise Mach number, resulting in less than ideal geometries for subsonic flight.

The theory of the longitudinal static stability of the hang-glider
The Aeronautical Journal, 1994AbstractThis paper describes the development of a simple theory of the longitudinal static stability of the hang-glider. The classical theory, as developed for the conventional aeroplane, is modified to accommodate the particular features of the hang-glider. When the appropriate assumptions are made, the theory provides simple insight into the controls

Effect of Upper-Surface Blowing on Static Longitudinal Stability of a Swept Wing
Journal of Aircraft, 1974A low-speed wind-tunnel investigation was conducted on a sharp-edged 75 deg delta wing, to determine the effect of upper-surface blowing on static longitudinal stability characteristics. The model incorporated nozzles, located at 0.50 mean aerodynamic chord length, supplied by compressed air to provide blowing on the upper surface.

Main static aeroelastic effects on sailplane longitudinal stability and control
1976In the paper the effects of the wing torsional deformation and of the fuselage bending deformation are considered, as being probabily the most important ones. The classical theoretical expressions for equilibrium and stability are therefore modified, in order to take into account these aeroelastic effects, and discussed.
