Accurate measurement of atmospheric parameters with high resolution needs advanced lasers. In this SBIR program we propose to develop innovative Q-switched high power 2.05micron fiber laser with pulse energy greater than 10mJ, repetition rate of 10Hz to 1KHz, and pulse duration of 200ns using our proprietary innovative highly efficient Tm-doped glass fiber. This new fiber laser will be an all-fibe ...

The GHz-rate phase-stabilized fiber-laser frequency comb system is proposed to be used as a light source for coherent Fourier transform spectroscopy. The system will be developed based on our proprietary glass/fiber technology, which features a low-cost, robust, highly stable, mid-infrared light source that enables the development of a robust portable c-FTIR spectrometer for absorption measurement ...

DESCRIPTION (provided by applicant): The detection and enumeration of circulating tumor cells (CTCs) has the potential to become a very powerful tool in cancer diagnosis and treatment. However, current technologies for CTC detection are not yet established in routine clinical practice. One reason is that CTCs are present in blood at an extremely low concentration of one in 10 million white blood c ...

There is currently no repair process to restore aluminum landing gear cylinders inner dimensions. The magnetron sputtering System (MSS) process has the potential of restoring outer cylinders IDs dimensions. This technology is similar to ion vapor deposition (IVD) aluminum, and meets the same specification MIL-DTL-83488. ES3’s RODS Phase I testing results were very positive and indicated that 606 ...

Temperature control has been a major concern during High Velocity Oxygen Fuel (HVOF) processing since it was originally utilized in the aerospace industry. Typically, temperature must not exceed 300oF to prevent heat damage/ tempering of the substrates on steel alloys, and even lower temperature requirements for aluminum and titanium alloys. These problems have prevented USAF depots from usage of ...

When the internal diameter (ID) of an aluminum alloy landing gear outer cylinder bore is damaged or worn there is currently very little that can be done to facilitate a repair. The main cause for early condemnation of aluminum alloy outer cylinders is excessive wear on the bore. The aerospace industry condemns many aluminum strut outer cylinders at a high cost. The cost to the USAF due to early ...

The rotorcraft aerodynamic interaction is a complicated problem and remains an extremely challenging aspect of rotorcraft analysis. This STTR is dedicated to developing a solution for the complicated rotorcraft aerodynamic interaction problem. The Phase I research coupled a state-of-the-art vortex particle method (VPM) with an unstructured Navier-Stokes CFD body surface solver and prototyped a hyb ...

The unsteady rotor wake is a complicated flow problem and remains a challenging aspect of comprehensive rotorcraft analysis. The Phase I research has shown that a viscous vortex particle method (VVPM) can provide a first-principle-based solution to the challenging rotor wake problem. Applying VVPM for wake vorticity transportation, while using a modern near body CFD solver for resolving vorticity ...

Aechelon Technology Night Mission System is the result of the Phase I and II efforts of the SBIR N014-156, “New Modeling and Simulation Technology for Night Vision Goggle Mission Rehearsal”. The system provides a computer simulation based replacement for the NVG terrain board, and is designed to be installed and operated in NiteLabs around the World. Aechelon Technology will provide two pre-pr ...

With increasingly demanding requirement in performance and capability of military vehicles, technical challenges in thermal management exist with regards to providing adequate cooling for their key components such as engine and power electronics, of which fluid coolant and materials to build heat exchangers are two critical factors to achieve the desired thermal management performance. In this SB ...
