Abstract

A power system for an aircraft having a plurality of power-consuming components, some of which have transient power requirements, which is greater than the average power requirement, the power system includes at least one generator, a power distribution buss, a non-battery power source, a battery power source, and a power controller selectively coupling the non-battery power source and the battery power source to the power distribution buss to satisfy the transient power requirements.

First claim

What is claimed is:

1 . A power system for an aircraft having a plurality of power-consuming components, some of which have transient power requirements, resulting in the aircraft having a transient-state power requirement in addition to an average power requirement, with the transient-state power requirement being greater than the average power requirement, the power system comprising:
at least one generator having a power output sufficient to supply the average power requirement; a power distribution buss coupling the generator to the power-consuming components; a non-battery power source; a battery power source; and a power controller selectively coupling the non-battery power source and the battery power source to the power distribution buss to satisfy the transient power requirements.

2 . The power system of claim 1 wherein the power controller couples the non-battery power source and the battery power source to the power distribution buss.

3 . The power system of claim 2 wherein the power controller couples the non-battery power source to the power distribution buss prior to the battery power source.

4 . The power system of claim 3 wherein the non-battery power source comprises at least one capacitor.

5 . The power system of claim 4 wherein the at least one capacitor comprises a capacitor bank.

6 . The power system of claim 5 wherein the battery power source comprises an emergency battery for the aircraft.

7 . The power system of claim 6 wherein the battery power source comprises at least one Li-Ion battery.

8 . The power system of claim 1 wherein the power distribution buss is a DC buss.

9 . The power system of claim 8 further comprising at least one converter configured to convert the power from at least one of the non-battery power source or the battery power source to the power of the DC buss.

10 . The power system of claim 9 further comprising a converter for each of the non-battery power source and battery power source.

11 . The power system of claim 8 wherein the DC buss is 270 VDC.

12 . The power system of claim 1 wherein the power controller comprises an input corresponding to the transient power requirement and selectively couples the non-battery power source and the battery power source based on the transient power requirement.

13 . The power system of claim 1 further comprising a load spectrum selection filter that identifies the average power requirement and the transient-state power requirement.

14 . The power system of claim 13 wherein the load spectrum selection filter comprises at least one of an analog filter, digital filter, linear filter, or nonlinear filter.

15 . The power system of claim 1 wherein the at least one generator power output is insufficient to supply the transient power requirement.
