This project extends Probability Bounds Analysis to model epistemic and aleatory uncertainty during early design of engineered systems in an Integrated Concurrent Engineering environment. This method uses efficient analytic and semi-analytic calculations, is more rigorous than probabilistic Monte Carlo simulation, and provides comprehensive and (often) best possible bounds on mission-level risk a ...

Hypersonic aircraft are subjected to extreme conditions with respect to mechanical thermal and acoustic loads. Materials with complex microstructure, such as Functionally Graded (FGM) and honeycomb, are expected to play a key role in such vehicles. Detailed numerical stress and thermal analysis of such materials, with conventional Finite Element Methods (FEM), is extremely difficult. The Fast Mult ...

Validating software is a critical step in developing high confidence systems. Typical software development practices are not acceptable in systems where failure leads to loss of life or other high costs. New software development tools are needed to radically reduce defect rates and enable the high levels of confidence required for safety- and security-critical systems. Lightweight verification ...

Honeybee Robotics proposes to build upon technology we have previously developed with Goddard Space Flight Center and redesign specifically for the lunar environment a "gear bearing" transmission. We intend to bring this technology to a higher Technology Readiness Level (TRL) for the number of applications imagined for future missions to the lunar poles requiring motors and drive trains ranging f ...

In response to the need for motors and actuators that can operate in the harsh venusian environment for extended periods of time, on the order of several hours to days, Honeybee Robotics proposes continued development of an extreme temperature brushless motor and a position feedback device (resolver or tachometer) and a demonstration of both in simulated Venus surface conditions. During Phase I a ...

As part of the NASA goal of "locating and characterizing lunar volatile resources", Honeybee Robotics proposes to investigate two novel technologies that both are powered by a new monopropellant, NOFB3, developed by Firestar Engineering. Honeybee will test key concepts for a pneumatic drill, intended for use in the lunar cold traps, and will also investigate a method for mining the top few centime ...

The need for in-flight event detection and monitoring systems is clear. To address this and other safety and security needs, IEM proposed the Reactive In-flight Multisensor Security System (RIMSS) an affordable system which would improve safety and security within an aircraft by: ?detecting abnormal events (including but not limited to unusual passenger/crew activities, losses of pressure, deviati ...

Impact Technologies, with support from the Georgia Institute of Technology and Honeywell, propose to develop and demonstrate a suite of real-time Fault Contingency Management (FCM) algorithms for application within an Integrated Vehicle Health Management (IVHM) system. The proposed FCM software will implement a novel vehicle subsystem fault accommodation approach based on a seamless integration be ...

Gases trapped in the propellant feed lines of space-based rocket engines due to cryogenic propellant boil-off or pressurant ingestion can result in poor combustion efficiencies, combustion instabilities, or long startup transients. To assist NASA in the use of the high performing liquid oxygen propellant combinations in space engines, IN Space proposes to investigate the feasibility of an innovat ...

This SBIR Phase I proposal introduces a fast speed bandwidth controllable tunable filter for hyper-/multi-spectral (HS/MS) imagers. It dynamically passes a variable narrow band spectral component (li) from the visible to Infrared (IR). The filter has the following projected specifications: >95% in-band transmittance, 1,000 nm tuning range, a few to hundred nanometer variable bandwidth, 0.05 ms/n ...
