| Abstract: |
The application and removal of a Large Scale dynamic loads is a transient phenomenon that takes time and its effects ripple through the whole system. Transient, dynamic power demand of large loads will result, as a minimum, in distorting the conventional AC generator line voltages beyond the MIL-STD-704E allowable limits. Furthermore, large scale dynamic loads are likely to cause a power source instability, generator trip off-line and even failure (shaft shearing) for both, AC or DC generators. It is also imperative that the full power will be available for the required duration with no degradation in quality on both load pulse ends (application and removal). There are several sources that interact affecting the performance of the power system: GCU control loop; Generator mechanical and electromagnetic properties and Load nature.
The decoupling of large scale dynamic loads from the prime power while stabilizing the power buses poses significant challenges, and needs to be explored.

| Benefits: |
The effort described in this proposal has a significant opportunity for commercialization in the military and commercial aerospace markets. Traditionally new concepts are initially tested and implemented on military vehicles which enjoy government funding, thus more likely to take risk with new and advanced products. The commercial market follows once the product is proven and reliable. More electric aircrafts are becoming reality with every passing day both for the military (e.g. JSF), and the commercial market (e.g. B787). The B787 carries generators with a total output which is close to 1.5 MW, thus solutions of the type explored in this solicitation will be required.
The continuous search for alternative energy will boost the production of hybrid vehicles and will accelerate the emergence of all electric cars on the market. The products and concepts developed in this program will be applicable to the all electric vehicle market which is much larger than the aerospace market.
