Lightweight and Compact Transient Electric Power Response Enhancement Concept Navy SBIR FY2007.1 Sol No.: Navy SBIR FY2007.1 Topic No.: N07-081 Topic Title: Lightweight and Compact Transient Electric Power Response Enhancement Concept Proposal No.: N071-081-1445 Firm: Altex Technologies Corporation 244 Sobrante Way Sunnyvale, California 94086 Contact: John Kelly Phone: (408) 328-8302 Abstract: Airborne electric power needs are becoming substantial, versus airframe propulsion power. Also, these electric power needs are applied in very short timescales that are not compatible with conventional gas turbine engine response capabilities. For these cases, the engine output and electric power quality are both degraded. A compact and lightweight means of improving the engine response to these transients is needed. Altex has identified a compact and lightweight engine modification that can address engine transient loads that are applied in less than 0.1 seconds. The approach is general and can apply to both military and civilian gas turbine engines. Preliminary analysis shows that the concept has potential. Under the proposed effort, the concept will be incorporated into a time dependent engine model, to assess performance of the concept under Navy specified load transients. In addition, brief tests of a key concept component will be carried out to support feasibility. Lastly, the performance and cost benefits of the concept will be quantified, and the advantages of the concept over alternatives will be determined. Benefits: A successful demonstration of the proposed concept will make available a compact and lightweight engine modification that will increase engine response to the load transients applied in less than 0.1 seconds. This will benefit the performance of military aircraft and missiles. In addition, the concept would also be beneficial to civilian off-grid combined heat and power systems that have transient load following problems. By implementing the concept, the complexity and cost of hybridized power systems would be reduced. These power generation units, which can save up to 46% in fuel use, will be important contributors to future power generation in the US, and their sales would be over $2 billion. Return
