: Aeroacoustic Characteristics of a Rectangular Multi-element Supersonic Jet Mixer-ejector Nozzle; This paper provides a unique, detailed evaluation of the acoustics and aerodynamics of a rectangular multi-element supersonic jet mixer-ejector noise suppressor. The performance of such mixer-ejectors is important in aircraft engine applications for noise suppression and thrust augmentation. In contrast to most prior experimental studies on ejectors that reported either aerodynamic of acoustic data, the present work documents both types of data. Information on the mixing, pumping, ejector wall pressure distribution, thrust augmentation and noise suppression characteristics of four simple, multi-element, jet mixer-ejector configurations is presented. The four configurations included the effect of ejector area ratio (AR = ejector cross-sectional area/total primary nozzle area) and the effect of non-parallel ejector walls. The configuration that produced the best noise suppression characteristics has also been studied in detail. The present results show that ejector configurations that produced the maximum pumping (secondary (induced) flow normalized by the primary flow) also exhibited the lowest wall pressures in the inlet region, and the maximum thrust augmentation. When cases having the same total mass flow were compared, one found that noise suppression trends corresponded with those for pumping (per unit secondary area). Surprisingly, the mixing (quantified by the peak Mach number, and flow uniformity) at the ejector exit exhibited no relationship to the noise suppression at moderate primary jet fully expanded M-j (the Mach number that would have been attained under isentropic expansion). However, the noise suppression dependence on the mixing was apparent at M-j = 1.6. The above observations are justified by noting that the mixing at the ejector exit is not a strong factor in determining the radiated noise when noise produced internal to the ejector dominates the noise field outside the ejector.

: Method and Apparatus for Mitigation of Radio Frequency Electric Field Peaking in Controlled Heat Processing of Hydrocarbonaceous Formations In Situ; The effects of radio frequency electric field peaking in the earth formations surrounding a conductor excited by radio frequency energy in the controlled in situ heat processing of hydrocarbonaceous earth formations are mitigated by providing an inert buffer region around the conductor to which radio frequency electromagnetic energy is supplied to produce an electric field within the earth formations. A portion of the earth formations is removed to accommodate insertion of the conductor at a desired location in the earth formations and to provide a buffer region between the conductor and the surrounding earth formations. The conductor is supported at the desired location in spaced relationship to the surrounding earth formations, the buffer region encompassing the principal region of the electric field enhancement region around the conductor where the probability of breakdown in the earth formations over the period of application of the radio frequency energy would be above a tolerable level. The buffer region is filled with dielectric material having an electric field breakdown level greater than that of the surrounding earth formation medium such that the probability of breakdown in the buffer region over the period of application of the radio frequency energy is tolerable. Preferably the filler medium has a power dissipation characteristic less than that of the surrounding earth formations., Sponsorship: IIT Research Institute, United States Patent

: Ethanol Ultra-Light Aircraft (Fall 2002) IPRO 317; Students will continue the work of previous IPRO teams to convert a Quicksilver MXII ultralight airplane to run on E85 fuel (85% ethanol, 15% gasoline). This is technically challenging because the plane uses a 2-stroke Rotax 503 engine, where the oil must be mixed in with the fuel. After the conversion, the plane will be flight-tested. In the mean time, the plane can be flown by students to enjoy the experience of flying a personal-type aircraft. In addition to the technical aspects, the project involves developing and maintaining relationships with sponsors, public relations, and a study of the potential for ethanol in the ultralight aircraft market. This project may eventually lead to the creation of a student organization responsible for maintaining and flying the ultralight aircraft., Sponsorship: Cushing Air Field, Brandon Klein, Larry Garick, Project Plan for IPRO 317: Ethanol Ultra-Light Aircraft for the Fall 2002 semester

: Subharmonic Noise Reduction Circuit; A subharmonic noise reduction circuit having an input terminal and an output terminal. The circuit has a first differential amplifier with a first non-inverting input, a first inverting input and a first output. The overall circuit input terminal is connected to the first non-inverting input. A low-pass filter is connected between the first output and the first inverting input. A second differential amplifier has a second non-inverting input, a second inverting input and a second output. The second output is connected to the overall circuit output terminal. A first resistor is connected between the second output and the second inverting input. A second resistor is connected between the first non-inverting input and the second non-inverting input. The circuit operates at unity gain of the DC voltage component and thus the DC output voltage follows the DC input voltage., Sponsorship: Illinois Institute of Technology, United States Patent
