Design of the MIT Breakdown Turbine Facility
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1985], 1985)
Summary: This report details the design, construction, and preliminary testing of a short duration (0.4 sec) test facility capable of testing 0.5 meter diameter, film cooled, high work aircraft turbine stages under conditions ...
Noise and performance of propellers for light aircraft : final report
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1980], 1980)
Introduction and Summary: The project "Noise and Performance of Propellers for Light Aircraft," Contract #NASl-15154 between NASA Langley and MIT, has now been completed, and the main results obtained are summarized in ...
Two-dimensional transonic aerodynamic design and analysis using the Euler equations
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1986], 1986)
A method is developed for the solution of the steady two-dimensional Euler equations with viscous corrections for transonic design and analysis problems. The steady finite volume integral equations are formulated on an ...
Effects of compressor endwall suction and blowing on stability enhancement
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1988], 1988)
An experimental investigation was carried out to examine the effects on stall margin of flow injection into, and removal out of, the endwall region of an axial compressor blade row. A main goal was to identify the mechanism ...
Newton solution of steady two-dimensional transonic flow
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1985], 1985)
A new method is developed for the solution of the steady, two-dimensional Euler equations for transonic flows. The discrete steady-state equations are derived in conservative finite-volume form on an intrinsic streamline ...
Induced strain actuation of composite plates
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1989], 1989)
Two models of induced strain plate actuator/substrate systems are developed and verified experimentally. Equations relating the actuation strains produced by the strain actuators to the induced strains found in the system ...
Measurements of aerodynamic damping on the MIT transonic rotor
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1981], 1981)
A method has been developed and demonstrated for the direct measurement of aerodynamic forcing and aerodynamic damping of a transonic compressor. The method is based on the inverse solution of the structural dynamic equations ...
Sound generation from a transonic compressor stage
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboratory, Massachusetts Institute of Technology, [1981], 1981)
Some aspects of the sound pressure wave characteristics produced by a transonic compressor stage are studied by the use of a simplified mathematical model involving flow parallel to a moving corrugated board. The critical ...
UNSFLO : a numerical method for unsteady inviscid flow in turbomachinery
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, 1988, 1988)
Introduction: There are four principal sources of unsteadiness in a single stage of a turbomachine in which there is one row of stationary blades (stators) and one row of moving blades (rotors). As shown in Fig. 1.1, ...
Flutter and forced response of mistuned rotors using standing wave analysis
(Cambridge, Mass. : Gas Turbine & Plasma Dynamics Laboraotry, [1983], 1983)
The torsion flutter and forced response of tuned and mistuned cascades is examined using a standing wave approach, as opposed to the traditional traveling wave approach used in cascades aerodynamic models. The motion of ...
