The STTR topic T5.01 envisions Autonomous Communications Systems (ACS) that can be aware of RF environment and the network status and learn from experience to enhance adaptability to nominal/anomalous conditions, self-reconfigure network connections, dynamically maximize performance in response to sensed conditions and mitigate system-level effects of outages and interference. In Phase II, Bluecom ...

New classes of aircraft, providing personal, on-demand mobility, are under development and are poised to revolutionize short-duration air travel.nbsp; The impetus for this work comes from advances in electronics and controls, and increases in electric motor power densities.nbsp; As these aircraft are integrated into the transportation system, they will encounter icing conditions that may challenge ...

Of interest to JPL, GRC and GSFC are laser communications telescopes (LCTs) with 30 to 100 cm clear aperture, wavefront error (WFE) less than 62 nm, cumulative WFE and transmission loss not to exceed 3-dB in the far field, advanced thermal and stray light design for operation while sun-pointing (3-degrees from the edge of the sun); -20deg; C to 50deg; C operational range (wider range preferred), a ...

MaXentric proposes the GAU2x2 wideband power amplifier system. The design combines MaXentric’s wideband RF PA technology with advanced digital signal processing in a single small footprint package. This tight integration is made possible through the extremely high efficiency and low power dissipation. Since very little power is dissipated as heat, the package and heat sink size can be minimized. ...

NASA has numerous requirements for in-space repair capabilities to aid future missions beyond earth orbit. A subset of these requirements is adhesive patch materials that provide permanent or temporary repair of a wide variety of surfaces with minimal surface preparation and that can operate in the space environment. This work will result in the production of a repair kit for in-space applicatio ...

ATA has demonstrated the primary innovation of combining a precision MEMS gyro (BAE SiRRS01) with a high bandwidth angular rate sensor, ATA's ARS-14 resulting in a low-noise, high bandwidth hybrid sensor, or HYSENS in a Phase I SBIR. The primary emphasis in Phase I development was the implementation and real-time demonstration of the sensor fusion algorithms that combined the output from a MEMS g ...

The need for higher performance fiber optic telecommunications receivers has provided the impetus for substantial progress during the last decade in the understanding and performance of InP-based linear mode avalanche photodiodes (APDs) for the wavelength range from 1.0 to 1.7 um. However, these advances have not been paralleled in the performance and availability of single photon avalanche diode ...

Valcor Engineering Corporation proposes to develop an advanced On Board Inert Gas Generation System, OBIGGS, for aircraft fuel tank inerting to prevent hazardous in-flight conditions and to mitigate their effect when they do occur. Aircraft fires represent a small number of actual accident causes, but the number of fatalities due to in-flight, post-crash, and on-ground fires is large. The novel OB ...

Silicone coatings are the system of choice for inflatable fabrics used in several space, military, and consumer applications, including airbags, parachutes, rafts, boat sails, and inflatable shelters. Commercial silicone coatings with improved mechanical, thermal and physical gas barrier properties are needed for a broad range of space, military, and commercial applications. The phase I program ...

DIRECT COMPUTATION OF TURBULENCE NOISE IS A LOGICAL APPLICATION FOR ADVANCED COMPUTATIONAL FLUID DYNAMICS, CFD, PROGRAMS RUN ON SUPERCOMPUTERS. THIS WOULD ELIMINATE THE HIGHLY EMPIRICAL ASPECTS OF PRESENT NOISE PREDICTION TECHNIQUES AND ENABLE STUDY OF ADVANCED HYPERSONIC PROPULSION SYSTEMS. HOWEVER, MANY OF THE SAME PERSISTENT PROBLEMS OF IMPLEMENTATION THAT EXIST IN AEROACOUSTIC THEORY AND MEASU ...
