Experimental apparatus for investigation of fan aeroelastic instabilities in turbomachinery

The application, installation, and monitoring of dynamic strain gage instrumentation on the rotating fan blades for subsonic stalled flutter mode of the first fan rotor are described. The engine installation, the modifications to the engine controls to obtain off schedule operation of the fan, engine aerodynamic instrumentation, and general data acquisition systems are discussed

On the numerical solution of second order differential equations in the high-frequency regime

We describe an algorithm for the numerical solution of second order linear differential equations in the highly-oscillatory regime. It is founded on the recent observation that the solutions of equations of this type can be accurately represented using nonoscillatory phase functions. Unlike standard solvers for ordinary differential equations, the running time of our algorithm is independent of the frequency of oscillation of the solutions. We illustrate the performance of the method with several numerical experiments

Urban and regional land use analysis: CARETS and census cities experiment package

The author has identified the following significant results. Temperatures in degrees Celsius were derived from PCM counts using the Pease's modified gray window technique. The Outcalt simulator was setup on the USGS computer. The input data to the model are basically meteorological and geographical in nature. The output data is presented in three matrices

Revised Attendance and Investment Parameters for the Relocated Marine World Africa USA at Vallejo

Harrison Price Company (HPC) reviewed their report dated September 1982 on the feasibility of relocating Marine World to Vallejo, California. The restated attendance parameters are based on reevaluated changes in the project and the market makeup which had occurred in the last two and a half years since the original study was prepared. HPC also estimated sustainable capital expenditures based on the revised projections
