Flutter-free operation of advanced transonic fan designs continues to be a challenging task for the designers of aircraft engines.

This is especially true for advanced forward swept designs that encompass an entirely new design space c...

| A Compact, High-Performance Continuous Magnetic Refrigerator - Shirron, Peter
We present test results of the first adiabatic demagnetization refrigerator (ADR) that can produce continuous cooling at sub-kelvin temperatures. This system uses multiple stages that operate in sequence to cascade heat from a continuous stage up to a heat sink. Continuous operation aids the usual constraints of long hold times and short recycle times that lead to the generally large mass of single-shot ADRs, and allows us to achieve much higher cooling power per unit mass...

| Structure of the Outer Cusp and Sources of the Cusp Precipitation during Intervals of a Horizontal IMF - Berchem, Jean
The cusp represents a place where the magnetosheath plasma can directly penetrate into the magnetosphere. Since the main transport processes are connected with merging of the interplanetary and magnetospheric field lines: the interplanetary magnetic field (IMF) Orientation plays a decisive role in the formation of the high-altitude cusp. The importance of the sign of the IMF B(sub Z) component for this process was suggested about 40 years ago and later it was documented by many experimental inve...

| Predicting Production Costs for Advanced Aerospace Vehicles - Bao, Han P.
For early design concepts, the conventional approach to cost is normally some kind of parametric weight-based cost model. There is now ample evidence that this approach can be misleading and inaccurate. By the nature of its development, a parametric cost model requires historical data and is valid only if the new design is analogous to those for which the model was derived. Advanced aerospace vehicles have no historical production data and are nowhere near the vehicles of the past...
