The objective of this SBIR proposal is for Analytical Services, Inc. (ASI) to develop design requirements for a client/server, Windows-based, database catalog (potentially, a Web-based distributed system) to track Radiation Hardening technologies and components of interest to the Missile Defense… More

The Missile Defense Agency (MDA) does not currently have an automated, centralized database to store Rad-Hardening (Rad-Hard) vendor data and corresponding test results. Portions of this data are currently stored in a spreadsheet, without consistency, distributed access, robust data search,… More

Analytical Services, Incorporated, teamed with Davidson Technologies, proposes a new approach to the characterization of drag and lift coefficient distributions for debris resulting from missile intercepts. The proposed approach utilizes both theoretical considerations and available measured data… More

In this SBIR project, a preliminary design of a highly accurate, highly repeatable impulse thruster will be completed. ASI, together with ATK, proposes to complete the preliminary design in parallel with the development of a comprehensive thruster model in a Monte Carlo environment that will… More

We propose a high-pressure, regeneratively-cooled combustion chamber that uses novel material selection for extreme reductions in mass. These materials are manufactured using proven processes, processes in which our two team members are expert. The combustion chamber liner will be made of a… More

We propose to develop a monopropellant replacement for hydrazine using eutectic mixtures of ionic liquids (EILs). These liquids offer us the ability to tailor fluid and chemical properties, are safe to handle and burn cleanly. They also offer potentially higher performance as a monopropellant than… More

ASI, teamed with GH Systems, proposes to integrate the comprehensive material and component database, RadCatT, with 3-D modeling, radiation transport, and electrodynamics software to provide a knowledge-based test environment simulation and test planning toolkit to support MDA rad-hard test… More

ASI is proposing a novel double base stabilizer concept that capitalizes on years of environmental research, including research into the reduction of NOx, SOx, and VOC gases released into the earth''s atmosphere. Our approach should not only provide better stabilizer performance, but will also… More

ASI proposes an innovative and numerically-efficient approach to the modeling of crack propagation in solid propellant rocket motors. Our technology uses a coupled fluid-structure interaction model that is enhanced with an embedded grid capability. Such an approach eliminates virtually all of the… More

Our proposed effort will be used to determine the feasibility of a deeply-throttleable aerospike engine that maintains constant specific impulse performance, regardless of the throttle setting. The design incorporates technology previously demonstrated under another SBIR, but extends it through… More

In our proposed effort, we intend to perform high temperature (100-200 Deg C) characterization of an ultra-advanced heat pipe to determine feasibility of using it in high temperature space radiators. In previous work, we have shown that the so-called "Qu Tube" achieves exceptionally high thermal… More

The Radiation Test Environment Simulation Toolkit (RadTEST) is capable of flowing down radiation environment requirements to the development of test plans, post-test analysis, and test reports. It''s capabilities include: --Access to RadCat Parts and Materials Database --Test Facility Catalog with… More

Decomposing monopropellant hydrazine across a spontaneous catalyst bed is the gold standard for small propulsion systems responsible for attitude control on satellites and spacecraft. Such a propulsion system is both simple and reliable, and offers reasonable performance. However, the simplicity… More

BMDS components must function reliably when exposed to radiation, including both nuclear weapon and natural space environments. Current tools will not allow correct evaluations of system performance. Since the current radiation environment tools were not designed to handle sub-orbital trajectories,… More

ABSTRACT: In our proposed Phase II effort, we will be demonstrating long-lived aqueous aluminum heat pipes. The work will directly demonstrate the corrosion inhibition character of two different aqueous work fluids and the long-term heat flux performance of our heat pipe designs at an operating… More

ABSTRACT: When a solid rocket motor propellant grain contains one or more flaws (cracks, debonds, casting voids) or develops them as it ages, the risks of testing that motor is significantly increased. The responsible authority must decide between testing a motor that may destroy expensive testing… More

In the proposed effort, ASI will be teaming with a major propulsion contractor to develop next generation thermal stabilizers for double base propellants. The scope includes chemical synthesis, propellant development and testing, and accelerated aging.

The long-term goal for this effort is to develop a low-cost, high-temperature thruster. Within the attitude control propulsion community, many efforts have focused on development of ultra-high temperature precious metal alloys and systems that give long life and good performance (e.g., Ir/Re). … More

ABSTRACT: In the proposed effort, ASI will demonstrate the feasibility of a practical, proven method for significantly increasing the heat transfer coefficient inside regenerative cooling channels. The technique, used in the electronics industry for high heat flux removal applications, requires… More
