During the last 16 years there has been a growing usage of a third system using 270 VDC. The 270 VDC system for aviation was first defined in MIL-STD-704B 17 Nov. 1975. Battery systems in this voltage area had been utilized in submarines since 1900.

 

The old reason for the 270 VDC system was increased power density and capacity.

The new interest is due to stealth concerns and design changes in modern fighter aircraft

 

Alternating current systems such as 400 Hz are not as stealthy as Direct Current (DC).

 

Although the 270 VDC military specification introduced in 1975 and last updated in 2004 (MIL-STD-704F) is still in effect, it does not contain all the requirements needed for the modern 270 VDC fighter aircraft.

 

The new generation aircraft, specifically the F/A-22 Raptor and the JSF (Joint Strike Fighter) F-35 Lightning, require a system that is more precise, has faster response, and is tailored to the specific requirements of the aircraft manufacturer. Simply put, although this is a 270 VDC system, the requirements define a power supply that far exceeds the old 2004 MIL-STD-704F performance. This required the creation of a 270 VDC system specific to the new aircraft.

 

The previous generation of fighter aircraft used a dual hydraulic system to move the flight control surfaces. This presented a large vulnerability should the aircraft suffer damage and fluid loss.

 

Newer aircraft now utilize multiple electrically driven hydraulic actuators at each control surface. This now requires the electrical system to respond to rapid load changes while maintaining a constant voltage.

 

Radar systems require more pulse power while the voltage stays constant.

 

The aircraft 270 VDC power system is ideally suited to meet all these demands. . This allows full maintenance including flight control response tests to be performed inside the hangar.
