Mission-oriented requirements for updating MIL-H-8501. Volume 1: STI proposed structure [PDF]
The structure of a new flying and ground handling qualities specification for military rotorcraft is presented. This preliminary specification structure is intended to evolve into a replacement for specification MIL-H-8501A. The new structure is designed

Rotorcraft handling-qualities design criteria development [PDF]
Joint NASA/Army efforts at the Ames Research Center to develop rotorcraft handling-qualities design criteria began in earnest in 1975. Notable results were the UH-1H VSTOLAND variable stability helicopter, the VFA-2 camera-and-terrain-board simulator ...

Application of GRASP (General Rotorcraft Aeromechanical Stability Program) to nonlinear analysis of a cantilever beam [PDF]
The General Rotorcraft Aeromechanical Stability Program (GRASP) was developed to analyse the steady-state and linearized dynamic behavior of rotorcraft in hovering and axial flight conditions. Because of the nature of problems GRASP was created to solve,

Scottish contributions to rotary wing flight [PDF]
This paper charts the history of rotorcraft development in Scotland. Beginning with the early efforts of Mumford to achieve rotor-borne flight, through the major technology advances of G and J Weir in the 30s and 40s up to present day activities.

Langley rotorcraft structural dynamics program: Background, status, accomplishments, plans [PDF]
Excessive vibration is the most common technical problem to arise as a show stopper in the development of a new rotorcraft. Vibration predictions have not been relied on by the industry during design because of deficiencies in finite element dynamic ...
