Advanced Technologies Group, Inc, (ATG) proposes a Hybrid-Advanced-Robust- Dependable (HARD) seal that exceeds the IHPTET and VAATE program goals. The seal design proposed is for air to air applications in the turbine and compressor sections. The ATG HARD seal is a non-contacting film riding seal design that will build on patented hybrid-Brush seal success at ATG. This vanguard design, when combined with advanced high temperature materials will provide unrivaled durability, reliability, performance, and maintainability at temperatures exceeding 1500F, differential pressures to 250 psi, and surface speeds of 1500 feet per second. These performance goals require innovative designs that far exceed current seal capabilities. The primary objective of this effort is to develop high temperature seals for implementation in the IHPTET and VAATE program, leading to extensive military and commercial applications. A specific US Army aircraft application has been identified for phase II testing. A commercial gas turbine manufacturer has requested a quote for development of advanced seals based on phase I results.

Based on the success of the phase I effort, Advanced Technologies Group, Inc. proposes the development of a Cryogenic Flow Sensor (CFS) for determining mass flow of cryogens in spacecraft propellant management. Current point sensor technology is incapable of determining high pressure, high flow rate cryogenic fluid quality and mass flow rate, and has proven to be inaccurate in attempting to rapidly measure cryogen depletion. If there is an abrupt change in fluid quality, turbo-machinery can over-speed causing catastrophic failure. The CFS will provide a means to avoid these failures as well as providing fluid quality data for a wide range of flow systems. Experimental hardware was able to detect the onset of two-phase flow and the presence of debris in the flow of water. The innovation clearly shows that it can discern between entrained gas bubbles and unwanted debris. The sensor has the potential to determine size and quantity of the contaminant. In addition, a non-intrusive method for determining the Mass-Flow?Rate of the fluid propellant has been designed, and is the focus of this phase II effort.

Our proposed receiver design will satisfy or exceed the requirements set forth in this solicitation. The key innovation is our melding of approaches – to produce a compact lightweight receiver with onboard processing that leverages picosecond timing resolution and burst acquisition methodology previously implemented by our team. The receiver architecture will utilize electronic gating, automatic gain control, timing and energy normalization and noise reduction onboard processing techniques in addition to digital demodulation to provide an optimal and versatile receiver design. No other off-the-shelf (OTS) solution currently exists to satisfy the Navy’s requirements.

Advanced Technologies Group, Inc. (ATG) proposes to develop an innovative High Powered Ram-Air-Turbine (HiRAT) capable of producing over 60kw of power at an air speed of 250 knots. During Phase I ATG will design, analyze and test a scaled turbine to determine feasibility. Preliminary analysis indicates that the ATG HiRAT is far superior to existing conventional turbine designs on several levels.

This SBIR development effort concentrates on blade tip clearance management in the high pressure turbine. Improved seals in this location of a gas-turbine engine provide the highest benefits to overall engine efficiency, service life, stability and stall margin. The COAS proposed will deliver a 3-5% decrease in SFC and a 30-50¢XC decrease in exhaust gas temperature. The ATG COAS is a non-contacting, compliant, film-riding seal design that builds on patented hybrid-Brush seal success at ATG. This vanguard design, when combined with advanced high temperature materials will provide unrivaled durability, reliability, performance, and maintainability at temperatures exceeding 2000„aF, differential pressures to 250 psi, and surface speeds of 1500 feet per second. These performance goals require innovative designs that far exceed current seal capabilities.
