This innovation is a tungsten-rhenium gauge that can be placed into an aft exit cone of a rocket motor. It will measure heat flux with time for the full duration of the RSRM (reusable solid rocket motor) nozzle environment with equal response time.

Efficient aircraft designs are increasingly desired in order to support the continued growth of the air transportation industry. Continued expansion of this vital mode of transportation is threatened due to concerns over ever-increasing emissions, noise, and the demand for fuel. Current airport runway,...

This invention relates to the safe, reliable, and repeatable testing under external load of the Extraction Force Transfer Coupling (EFTC) currently used in the extraction of airdrop platforms from both the C-17 and C-130 cargo transport aircraft. The invention enables functional testing of the EFTC...

A concept for recovering reusable spacecraft or capsules, or reusable rocket boosters, has them land on an airbag-based, cushioned platform positioned on a highly maneuverable hovercraft. This landing method would have performance advantages over conventional approaches to reusability by placing most of the landing...

A novel, short-contact-time Microlith Sabatier reactor system for CO2 reduction offers a significant advance in support of manned spaceflight. Compared to the current and prospective alternatives (including microchannels), the reactor is much smaller and lighter, more energy...

The Nitrous Oxide Ethylene-Ethane (NEE) engine uses nitrous oxide as an autogenously pressurizing oxidizer, and a mixture of ethane and ethylene is used in the same manner as fuel. Initially, the ethane and ethylene mixture has the same vapor pressure as the nitrous oxide. By using the autogenous pressurization...

A method was developed for obtaining proper fluid distribution through parallel gun-drilled passages and for being able to inspect the actual drilled passages to guarantee that the designed minimum wall thickness is not violated. This invention uses one feature that addresses...

A standoff sample collection system would be capable of quickly obtaining a sample from environments as varied as comets, asteroids, and permanently shadowed craters on the Moon from vehicles ranging from traditional planetary spacecraft to platforms such as hovering rotorcraft or balloons at...

A new technology provides for automated sample handling and movement of coarse-grained powder or other solid materials to enable analysis by a robotic or totally automated computer system. Currently, many analytical instruments require a powder sample to control the shape and/or volume of the...

Developers from Harvard’s School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering have produced the first untethered soft robot — a quadruped that can stand up and walk away from its designers. The researchers were able to scale up earlier soft-robot...

Spacecraft internal active thermal control systems (ATCSs) typically use water or a water mixture as their working fluid. A gas-charged bellows accumulator pressurizes the system and provides liquid inventory control. If only a single internal ATCS loop is used, the accumulator...

Producing electric power for space applications is challenging. Although short-term missions can use batteries or fuel cells, these sources are not practical for durations longer than one month. Photovoltaics become less attractive as the distance from the Sun increases, and they are...
