A Numerical Criterion for F-16 Fighter Pitch Maneuver Boundary

Toward the development of a criterion for fleet effectiveness in the F-4 fighter community.

Design of Longitudinal Control System for a Nonlinear F-16 Fighter Using Mss Method

In automatic flight control system or autopilots, multiple specifications criteria are needed to be satisfied concurrently, such as good holding (small static altitude holding error), fast response, smooth transition (less oscillation, overshoot). So how to design the MSS (Multiple Simultaneous Specification) controller effectively and practically is a very significant and challenging job. Liu ...

F-TRANSFORM FOR NUMERICAL SOLUTION OF TWO-POINT BOUNDARY VALUE PROBLEM

We propose a fuzzy-based approach aiming at finding numerical solutions to some classical problems. We use the technique of F-transform to solve a second-order ordinary differential equation with boundary conditions. We reduce the problem to a system of linear equations and make experiments that demonstrate applicability of the proposed method. We estimate the order of accuracy of the proposed ...

A Boundary Criterion for Cubulation

We give a criterion in terms of the boundary for the existence of a proper cocompact action of a word-hyperbolic group on a CAT(0) cube complex. We describe applications towards lattices and hyperbolic 3-manifold groups. In particular, by combining the theory of special cube complexes, the surface subgroup result of Kahn-Markovic, and Agol’s criterion, we find that every subgroup separable clos...

Oxygen Mask Related Nasal Integument and Osteocartilagenous Disorders in F-16 Fighter Pilots

BACKGROUND A preliminary survey showed half of the participating Royal Netherlands Air Force (RNLAF) F-16 fighter pilots to have nasal integument and osteocartilagenous disorders related to wearing in-flight oxygen masks. AIM To make an inventory of these disorders and possible associated factors. METHODS All RNLAF F-16 pilots were requested to fill out a semi-structured questionnaire for a...
