The overall objective of this proposal is to develop a high temperature, motor drive based on silicon carbide (SiC) power semiconductors for controlling a switched reluctance motor (SRM). This motor drive will be suitable for use in either anelectromechanical actuator (EMA) or an electrohydraulic actuator (EHA). The proposed Phase II effort focus is the additional research and development needed t ...

SBIR Phase II proposal is submitted here for evaluation. A compact millimeter-wave waveguide-integrated low loss antenna with a forward tilted fan-beam covering about 90x3.2 degreesis proposed. A total of eight antennas will be integrated into a 4-inchdiameter package. The package also will include at least two sets of oscillator-upconverter modules and four receiver mixers to generate four set ...

The overall objective of this Phase II effort is to conduct an operational evaluation of a repaired Ceramic Matrix Composite (CMC) component, such as a gas path liner for an advanced F119 exhaust nozzle. CMC repair methods developed in Phase I will berefined and extended to cover three levels of damage: 1) surface ply loss, 2) delaminations and ply rupture, and 3) through-hole damage. The Phase I ...

We propose to research and develop an integrated, multi-sensor Electronic Sight Unit (ESU) to replace the current opto- mechanical M67 mortar sight. While the technologies are familiar individually (GPS attitude, magnetometers, optical encoders, MEMS andfiber optic inertial sensors), we will demonstrate full function indirect and direct lay fire control solutions with a fraction of the weight and ...

The next generation of amphibious assault vehicles, the AdvancedAmphibious Assault Vehicle (AAAV), will be capable of carrying 18marines at a water speed of 25 knots and a ground speed of 45mph, a significant improvement over current vehicles. However,preliminary measurements indicate the presence of extremely highnoise levels inside the vehicle cabin. This noise, potentiallyin excess of 120 dBA ...

Payload planners of earth imaging systems have always struggled with the fundamental problem of designing a delicate, pointing system that survives the severe vibro-acoustic environments of launch. The standard solution is to mass load the spacecraft busand lock down the pointing stage during launch. However, the parasitic mass and unwanted complexity are unacceptable for future RLV systems. C ...

The PowerSail is a new paradigm in space systems that offers significant performance and cost improvements for on-orbit power generation. The PowerSail will co-orbit in formation with a satellite, with flexible interconnects and a robotic arm managing thelink between the two structures. The research will produce key technologies that will enable realization of the PowerSail concept. By enabling ...

Shock is a major problem for spacecraft, and is the largest dynamic load on spacecraft during launch on large launch vehicles. Shock to spacecraft during launch comes from two sources, the launch vehicle (fairing separation being one of the largest shocksources) and the spacecraft separation event. A whole-spacecraft shock isolation system will prevent shock produced by the launch vehicle from r ...

This effort is concerned with the design of CES, a rule-based expert system for forecasting vehicle corrosion and deterioration. Weight reduction and increased performances has driven the automotive industry to incorporate magnesium and aluminumcomponents in areas such as the engine compartment, frames and chassis. Unfortunately, these metals are highly active on the galvanic series and therefor ...
