The Zero Gravity Mass Measurement Device (ZGMMD) provides the ability to measure the mass of samples in a microgravity environment, like that found on the International Space Station (ISS). One of the primary measurements often taken during science experiments is mass. This is even more relevant in biology, where mass is often one of the key measurements taken for analysis. During the Phase I effort, a ZGMMD prototype was developed, tested, and demonstrated the feasibility of a means to determine the mass of samples less than 1kg, without the use of earth's gravity. The ZGMMD's innovative way of determining the mass, of low mass objects, in microgravity environments has been shown to be feasible, and effective. The Phase I prototype has shown to be able to provide great mass measurement capabilities, exceeding the Phase I requirements, specifically in accuracy and precision.

ORBITEC proposes to develop the Advanced Reversible Cryogenic Thermal Energy Storage (ARCTES) system, which will provide temporary backup cooling for circulating helium gas coolant in high-temperature superconducting (HTS) systems for naval applications. The ARCTES will rely on an initially-frozen cryogen to absorb heat from the passing helium gas through a heat exchanger device. As the working cryogen continues to absorb heat, it will warm to its melting point, melt, and then continue to warm as a liquid and evaporate to the vapor phase. The ARCTES provides a compact, lightweight, and simple means of passively storing cooling capacity. For purposes of comparison, the current state-of-the-art backup cooling system relies on the heat of vaporization of liquid nitrogen, which provides approximately 200 joules per gram (J/g) of cooling capacity. The ARCTES system will improve upon this figure by 50%, approaching 300 J/g of cooling capacity. The ARCTES system has the additional advantages of requiring neither LN2 resupply nor a vent to atmosphere for boil-off gas, and of being passively reversible. ORBITEC has extensive experience in the formation and management of solid cryogens as part of our propulsion system development, and we are well-qualified to perform this work.

ABSTRACT: ORBITEC will develop a new diagnostic to acquire simultaneous planes of velocity and temperature data at very high repetition rates. This diagnostic relies on a novel pulse burst laser system, a phosphor thermometry technique, and the mature PIV method. The work plan will involve developing and testing the laser, refining the integrated technique, and demonstrating it in a supersonic flow. The result will be a new diagnostic that will be very useful to the combustion community for generating temporally and spatially resolved data in reacting flow and for validating CFD models. The resulting products will have a promising market in both military and civilian applications. BENEFIT: This STTR program will produce several viable products: The PIV+T diagnostic, the pulse burst laser, the phosphor particles, and testing services. Because the PIV+T technique is designed for turbulent reacting flows, it will have applications in air-breathing engines, IC engines, and rocket engines. The markets include many branches of the military and many civilian companies.

ORBITEC proposes to develop the Miniature Nontoxic Nitrous Oxide-Propane (MINNOP) propulsion system, a small bipropellant propulsion system which we offer as an alternative to miniature hydrazine monopropellant thrusters for CubeSat-class spacecraft. As compared to state-of-the-art hydrazine systems, MINNOP propulsion will provide significant increases in specific impulse (in bipropellant mode) and comparable levels of minimum impulse bit (in cold gas mode), and it will do so with a nontoxic, environmentally benign, self-pressurizing set of propellants. In Phase I, we will focus on demonstrating the operation of the bipropellant thrust chamber, and ignition of that chamber within appropriate weight constraints. Our preliminary propulsion system design is intended to occupy 1U of a 3U-size CubeSat.
