The Candent Technologies “Reduced Cavitation, High Efficiency Outboard Propulsor for Small Planing Craft” Phase II program is structured to develop an advanced waterjet propulsor for the Combat Rubber Raiding Craft (CRRC). This new axial flow waterjet propulsion system is designed as a “bolt on” assembly that replaces the lower unit of the existing MFE 55 outboard motor. This new propulsio ...

Group 2-3 UAS engines have low mean time between overhauls (MTBOs), often with as little as 200-400 hours before maintenance must be conducted.This leads to significant maintenance cost and logistics tail for deployed operations.Two-stroke piston and rotary engines for Group 2-3 platforms have common maintenance drivers such as carbon fouling, and wear of cylinders, housings and bearings.Phase I r ...

The Air Force rebuilds and tests many aircraft and ground-power generators each year, involving many hours of loaded run-time with dissipative load banks. To improve facility energy efficiency and to have a positive environmental impact, a regenerative ac/dc load bank is proposed to push power from generator testing back to the electric grid. The proposed generator power recapture unit (GPRU) will ...

"Improving filtration technology for military vehicle engine lubrication systems remains a significant challenge. Equipment failures due to improper or excessive periodic maintenance contribute substantially to the overall cost of maintaining militaryfleets and create combat ineffectiveness during mission critical operations. Current systems have short filter life span and do not provide satisfa ...

"In future advanced military diesel engine propulsion systems, the engine's tribological considerations have been limited by the temperature capability of the lubricating fluid. Thermal oxidation resulting in lubricant breakdown and formation of films anddeposits are typical causes of engine failure in the high operating conditions projected for Low Heat Rejection (LHR) type diesel engines. Work ...

A FEASIBILITY STUDY ON THE DEVELOPMENT OF A STOICHIOMETRIC DIESEL ENGINE IS PROPOSED USING THE THERMAL IGNITION COMBUSTION CHAMBER. THE ADIABATIC DIESEL ENGINE WITHOUT WATER OR AIR COOLING ALLOWS THE THERMAL IGNITION CHAMBER TO STORE HEAT DURING COMBUSTION AND RELEASE THE ENERGY FOR IGNITION IN THE FOLLOWING CYCLE. INJECTION OF FUEL ON TO 1800-2000 DEG. F WALL TEMPERATURE WILL PREPARE THE FUEL FOR ...

This Phase II SBIR project will continue the development of an optical sorter that will be used to estimate drop sizes in sprays. The optical sorter will determine the size of drops in the 0.1 to 10 microns range. Drops in this size range are prevalent in the automobile industry, where the fuel injection pressures have increased tremendously over the past two decades. These newer injectors provide ...

The movement to more-electric architectures during the past decade in military and commercial airborne systems continues to increase the complexity of designing and specifying the electrical power system in such architectures. In particular, electrical starter/generators (ES/G) on airborne systems have become much more complex in terms of design due to growth in electrical power and energy require ...

THIS PROPOSAL IS TO DEMONSTRATE FEASIBILITY OF INSERTION OF SIALIC ACID MOLECULES INTO MEMBRANES OF LIPOSOMES CARRYING HEMOGLOBIN. THE LIPOSOMES MAY BE PROVIDED BY NAVY CONTRACTORS OR PREPARED BY OFFEROR ACCORDING TO CONTRACTORS' SPECIFICATIONS FOR FOMULATION. THE ADDED SIALIC ACID WILL PROTECT THE LIPOSOMES FROM CLEARANCE BY THE RETICULOENDOTHELIAL SYSTEM AND THEREBY INCREASE THE RESIDENCY TIME O ...

Phycotransgenics goal is to develop a vaccine delivery system using microalgae to reduce diseaseassociated costs for aquaculture. To accomplish this, we transformed Chlamydomonas, a single-cell algal species, with an antigen gene. Through our Phase 1 Program, we demonstrated that: 1) an antigen expressed in our algae can elicit an immune response in fish, and; 2) using our microalgal delivery syst ...
