ABSTRACT: The physical scalability of Si based nonvolatile memory is problematic for the terascale integration of space memory. In particular and with regards to Flash, this problem is two-fold as device designs breakdown and photolithographic patterning approaches its limits to minimum feature size. Whereas phase-change and ferroelectric polymer devices have shown promise to scale beyond Flash ...

ABSTRACT: An ability to reduce the weight of cables has the potential to provide significant cost savings, reduce maintenance and improve reliability of satellites. The costs of developing and producing satellites are linearly proportional with the satellite"s weight, with each kilogram costing around $1 million when delivery-to-space costs are included. With global satellite launches expected to ...

Modern combustion systems such as liquid rocket engines and gas turbines are characterized by high operating pressures and temperatures due to increased power-density. Thermal radiation has significant impact on both heat fluxes at the wall and on physical phenomena controlling the combustion process at these conditions. Coupling between radiation, turbulence and chemistry can have a large effect ...

The objective of this proposal is to develop Selective Availability Anti-Spoofing Module (SAASM) compliant GPS receiver for Geosynchronous Earth Orbit (GEO) applications. In this proposal, we explore an approach to design the GEO GPS SAASM receiver based on improved techniques for signal acquisition (or detection) and then signal tracking (and demodulation) of weak GPS signals. GPS signals availa ...

Archangel Systems, Inc. proposes a feasibility study coined Triaxial Accelerometer with Low Offset and Noise (TALON) to meet the accelerometer needs for DoD"s next-generation IMUs in agile missile programs. DoD targets for IMU size, weight and power (SWAP) budgets are aggressive. To meet these requirements, TALON leverages prior Archangel work for DARPA"s NGIMG project. Specifically, the MEMS a ...

We propose to develop a space based radiation hardened GPS transmit antenna capable of forming spot beams to enhance the GPS signal on the ground by greater than 5 dB. It is expected that our transverse compound hybrid antenna will provide as much as 30 dB gain over a hemispherical antenna allowing enhanced signals over specific areas as large as 500 km. A tradeoff between spot size and signal g ...

ABSTRACT:Emergence and feasibility for flexible body-worn electronics and particularly medical patches requires high performance electronics capability.The problem is that these new technologies must have flexible and conformal physical formats and conventional electronic components are not in any way flexible. In the CLAS Phase I program, a new flexible high-performance manufacturing and material ...

ABSTRACT: Military and industrial personnel are often exposed to RF electromagnetic energy which can cause thermal and electrokinetic biological effects. To understand these effects, AFRL is using computational electromagnetic tools to predict RF energy deposition and thermal effects in humans. Unfortunately, high resolution thermal simulations are computationally very expensive. The goal of this ...

ABSTRACT: To provide reliably secure communications, development of practical quantum optical devices for ground-to-space quantum key distribution is a necessity. The overall goal of this Air Force effort is to develop and deliver a single photon source based on heralding to indicate when a photon has been generated. The proposed device will produce single photons on demand with high efficiency ...

ABSTRACT: SIFT, with subject matter expertise from the UAS pilots and sensor operators (SOs) at UAV Associates and in sensor processing capabilities from Ball Aerospace, will develop FLA2SH (Flexible Levels of Adaptable Autonomy for Sensor Handling) to extend and integrate with AFRL"s successful Flexible Levels of Execution-Interface Technologies (FLEX-IT) architecture for multi-modal delegation ...
