Previous Programs
DoD (Navy) Topic No. SBIR N121-054
Phase I and Phase II, including design, fabrication, and testing of a heavy fuel engine and propulsion system for the Modular Unmanned Small Craft Littoral (MUSCL) Unmanned Surface Vehicle (USV), plus system integration, construction, and testing of the prototype boats. One of the three boats delivered to the Navy is pictured below.
The heavy fuel engine developed under this program has potential application as a propulsion system for unmanned ground vehicles as well as prime mover for small power generaton sets for tactical applications. Candent Technologies is teamed with Orbital Engines of Australia to develop the small heavy fuel engine that powers the MUSCL USV
Candent developed MUSCL USV powered by a 5kW heavy fuel engine
Army SBIR Topic No. A03-69
Phase I, II, and II+: designed, fabricated, and tested advanced 750-hp full scale, prototype high efficiency gas turbine engine capable of meeting the Army’s Small Heavy Fuel Engine (SHFE) program goals. This advanced three spool engine has a pressure ratio of 18:1, a specific fuel consumption of 0.42 lbs/hp-hr and a patented shaft clutching system that provided significantly improved part power fuel consumption.

Candent Model 307 High Pressure Ratio Turbine Engine - Marine Version
Navy SBIR Topic No.N092-122
Phase I, completed preliminary design of twin gas turbine propulsion system for 11m small craft using Candent designed high efficiency 540 hp engines modified for marine applications. The effort included the design of the complete installation and reduction gearbox systems.
This installation of two 600 hp marine versions of the Candent Model 307 provides over 1200 hp for small craft propulsion
Navy SBIR Topic No. N103-229
Phase I and II, designed a closed air cycle waste heat energy recovery system for Navy ships that use Ship Service Gas Turbine Generators (SSGTG), and completed fabrication and testing of prototype turbomachinery components. This system can recover approximately one megawatt of electrical power from the waste heat of the SSGTG exhaust. This increases the power available by approximately 20% for no additional fuel consumption. The system uses air as a working fluid so there are no very high pressure systems as are found in systems using supercritical CO2 as a working fluid. The system is shown below mounted above the SSGTG as it would be found in a typical installation.
Air Force SBIR Topic No. AF161-072
Phase I, analysis, concept development, preliminary design of prototype structurally embedded heat exchanger to improve turbine airfoil cooling
