For future long-range theater ballistic missile defense, aircraft-mounted LADAR systems require eyesafe laser transmitters that produce higher pulse energy and better beam quality than currently available optical parametric oscillators (OPOs) pumped by diode-pumped Nd:YAG lasers. Aculight proposes a novel laser transmitter approach that can simultaneously generate the required pulse energy, b ...

Development is proposed of a new, rotary form of Stirling cryocooler which offers longer operating life and much lower vibration than reciprocating forms of cryocoolers. The proposed machine has fewer moving parts to wear and can be completely balanced to eliminate vibration in all planes by simple counterweights on the shaft, which is not possible in reciprocating machines. The rotary desi ...

Ceramic armor is increasingly gaining acceptance as the armor material of choise for defense applications. One way to increase the ballistic performance of ceramic armors is to enhance their fracture resistance br decreasing their gain size (i.e. decreased flaw size) within the microstructure. Nanocrystalline powders, by virtue of their nanometer scale partical size, offer excellent potential to ...

Presently there are no broadly tenable, narrow linewidth souces that operate throughout the mid-infrared (mid-IR) region of the spectrum, from 1 to 5 microns. Traditional sources have very low spectral brightness (low power per unit spectral bandwidth). This proposal describes a novel approach to produce a source with very high spectral brightness, tunable over the range of 1.1 to 4.3 microns. ...

The Air Force Phillips Laboratory is seeking approaches for demonstrating frequency agile COIL (chemical oxygen iodine lasers) operating near 1.31 microns and at 10 kHz rep rates. Frequency conversion approaches must be capable of handling high average power levels, greater than 10 kWatts. Converting a COIL device to high peak powers will be necessary for frequency conversion. The approach prop ...

The primary objective of the proposed project is to demonstrate through detailed simulation, performance and low-cost feasibility of SICOM's innovative rapid-acquisition digital data (RADD) demodulator for high data rate burst or CW communications. The demodulator incorporates several innovative features, including zero-preample determination of symbol timing, carrier phase, and carrier frequency ...

A liquid chemical hydride-based hydrogen storage system is proposed for high density hydrogen supply for fuel cell power generation applications. Research works performed at MER showed that certain liquid hydrides can be catalytically dehydrogenated at temperatures as low as 150¿C. The released hydrogen gas can be withdrawn from the system through a hydrogen permeable membrane to achieve comple ...

There is a need for a passive sampler that can measure chemical simulant vapor concentration in real time, and under nuclear- biological- chemical-protective light-weight clothing. Existing samplers and sampler design concepts are not able to meet this need because of bulk, difflision limitations, contamination potential, durability, sensitivity, selectivity, reliability, and cost. Nanomaterials ...

A study will be conducted to develop actively-cooled structural concepts for high heat transfer engine inlet regions of scramjet engines. The program is directed toward the HyTech missile system and employs laminated foil microchannel cooling technology. The program will consist of four basic tasks: (1) definition of design requirements; (2) design trade studies to develop the optimum ...

Measuring the inherent optical properties of the ocean has historically been a very difficult problem. The most widely used in-situ sensor has been the transmissometer, which measures the transmission of a light beam over a short pathlength in
