The research and development effort proposed herein will provide the foundation and methodology for building a simplified structural and dynamic analysis code for missile and deployed object design analysis. the code will generate all critical design loading conditions using aerodynamic, propulsion,… More

A device is herein proposed which can be incorporated into a projectile, such as a rail gun projectile, to control attitude. the device, a modified nutation damper, has essentially only one moving part and so can be made, to exhibit extreme strength. by controlling the projectile's attitude during… More

The objective of the study effort is to produce complete specifications, a detailed design, and performance calculations for a 'frequency-stepped' ground penetrating radar (gpr) system. the frequency stepped approach will allow improvements over the typical 'short-pulse' radar by improving bandwidth… More

The objective of the study effort is to produce specifications, a detailed design, and performnce calculations for three sensors which are integrated to form a mine detection system. the sensors include a frequency stepped ground penetration radar, a dual band infrared scanner, and a video scanner.… More

Coleman research corporation (crc) proposes to develop the capability to perform computer simulations of upper-atmosphere balloon drift patterns. models of zero-pressure and super-pressure balloons will be developed to account for buoyancy, mass properties, aerodynamic configuration, propulsive… More

This study will lay the groundwork for the development of a simulation system which will permit the rapid and thorough evaluation of new and emerging icbm guidance and control technologies. existing simulations and models of subsystems and components will be collected, validated and screened for… More

The objective of our phase i effort is to produce an authentic simulation of agm-84 (harpoon) attack profiles against hostile ships operating independently and in unison. we will simulate weapon launch from s-3b and a-6e aircraft separately and in a coordinated operations scenario. the simulation… More

The electronics design problem associated with ultra-high g physical environments is being addressed, using as a basis the development of crytals for use in crystal oscillators suitable for electromagnetically launched (rail gun) projectile applications. the study is focusing on the structural… More

Composite materials are formulated from combinations of fibrous and solid (plastics and/or metals) which are designed to improve the life span of the base material. this study will be required to gather data on state-of-the-art composite materials and establish a database to determine the… More

Crc proposes a design study to apply two developmental wrap-around fin (waf) techniques to air force guided munitions. these flexible waf designs differ from conventional waf's in that they become straight when deployed. as a result they avoid the undersirable (and difficult to predict and to… More

A remote periscope is proposed that can be deployed from a submarine. the device replicates the functions of a conventional periscope while maintaining its unique features. preliminary requirements on the new device have been set. the device should rise to about 4 m above the waterline for viewing… More

Digital signal corporation proposes to replace the current vehicle crush measurement system of highly trained investigators using time consuming methods with a portable, rugged, easy to use laser radar/camcorder system. the benefits range from easy to reproduce and corroborable results to an… More

The objective of the proposed research is development of practical, multivariate model predictive control (mpc) for fossil power plants. the approach used here involves the development of a generic, reduced-order model (rom) which captures the dominant static and dynamic characteristics of power… More

An adaptive attitude control system for a space-based interceptor will ameliorate the effects of torque disturbances when firing a divert thruster with the line of force offset from its center of mass. The adaptive control algorithm is based on a simplified version of a model reference adaptive… More

Conventional guidance algorithms for exoatmospheric kinetic energy weapons are based on algorithms developed for endoatmospheric missile systems. With the appropriate assumptions and definitions, the algorithms can be shown to be optimal. Although they perform well under limited circumstances, the… More

The assignment problem is a linear programming problem in which the goal is to determine the assignment of sources to destinations so as to minimize the cost. This arises in numerous areas, including assigning interceptors to threats in battle. Generally, the solution is very time consuming when the… More

The objective of our phase i effort is to explore techniques, and develop approaches to provide safe real-time audiovisual cues for the inbound and impact noises, concussion, debris, flash (night visible), smoke, and dust of indirect fire weapons used in training at the national training center… More
