A microprocessor controlled automatic data logging system (ADL)
(1977-06)
This paper describes a digital, microprocessor
controlled data acquisition system which optimizes
man/machine communications. The processor provides
digital feedback control, data collection over any
number of channels ...
Wind tunnel wall corrections for arbitrary planforms and wind tunnel cross-sections.
(Monterey, California. Naval Postgraduate School, 1977-06)
A computer program was developed to obtain the wind
tunnel wall corrections for wing angle of attack, induced
drag, and pitching moment in incompressible flow. The
vortex lattice method is used for computation of ...
Evaluation of and operational procedures for a helicopter simulation system utilizing an integrated electronic instrument display.
(Monterey, California. Naval Postgraduate School, 1977-06)
This report discusses the evaluation and documentation of an integrated electronic instrument display designed to investigate stability and control of a helicopter during precision hover operations. The equations of motion, ...
EA-6B Mission Planning Program
(Monterey, California. Naval Postgraduate School, 1977-06)
The EA-6B mission Planning Program is designed for use by aircrewmen deployed on board aircraft carriers. it is an interactive computer program for automated sorting, retrieval, display and plotting of information. All ...
Data acquisition system for unsteady aerodynamic investigation.
(Monterey, California. Naval Postgraduate School, 1977-06)
This paper describes the design and implementation of a microprocessor-based high-speed digital data acquisition and reduction system suitable for use in time varying signal analysis as encountered in unsteady aerodynamic ...
Initial unsteady aerodynamic measurements of a circulation controlled airfoil and an oscillating flow wind tunnel.
(Monterey, California. Naval Postgraduate School, 1977-06)
Steady state results of lift developed by varying the
momentum blowing coefficient (C(ϻ)) upon a refurbished
Circulation Control Rotor (CCR) airfoil section were favorable.
This thesis was an experimental investigation ...
Dissection and analysis of electroencephalograms of subjects doing a simulated pilot's task.
(Monterey, California. Naval Postgraduate School, 1977-03)
A method for dissecting and analyzing
electroencephalograms for the presence of any
distinctive characteristics is presented. Data are
presented which strongly indicate the presence of a
preferred frequency, in the 70 ...
An investigation of the recovery processes in 7075-T651 aluminum responsible for a stress decay during dynamic loading histories
(Monterey, California. Naval Postgraduate School, 1977-03)
This thesis investigates stress relaxation, strain softening, strain hardening and anelastic behavior as potential recovery processes in 7075-T651 alloy. A series of tests were conducted utilizing uniaxial specimens of ...
A stability analysis of the proposed circulation control rotor (CCR) prototype
(Monterey, California. Naval Postgraduate School, 1977-03)
The rotor system of the proposed XH-2/CCR (Circulation Control Rotor) prototype aircraft and the state variable format of the airframe equations of motion are described. Through a study of the eigenvalues and eigenvectors ...
A study of spectrum loading and range-pair counting method effects on cumulative fatigue damage
(Monterey, California. Naval Postgraduate School, 1977)
This thesis is a study of cumulative fatigue damage. Variations in cumulative fatigue damage resulting from block loading spectra and randomized cycle loading spectra are investigated. Fatigue damage results show the merit ...
