Abstract
An example system includes a common electric starter controller configured to control electric starters of a plurality of gas-turbine engines that are configured to propel an aircraft, wherein the common electric starter comprises: a driver configured to generate, using electrical energy sourced from a battery of the aircraft, power signals that control the electric starters; and a plurality of bus bars configured to directly connect the common electric starter controller to the battery and transport the electrical energy from the battery to the common electric starter controller.
Claims15
A system comprising:
- a common electric starter controller configured to control electric starters of a plurality of gas-turbine engines that are configured to propel an aircraft, wherein the common electric starter controller comprises:
- a driver configured to generate, using electrical energy sourced from a battery of the aircraft, power signals that control the electric starters;
- and
- a plurality of bus bars configured to directly connect the common electric starter controller to the battery and transport the electrical energy from the battery to the common electric starter controller.
A system comprising:
- a common electric starter controller configured to control electric starters of a plurality of gas-turbine engines that are configured to propel an aircraft, wherein the common electric starter controller comprises:
- a driver configured to generate, using direct current (DC) electrical energy sourced from a battery of the aircraft, alternating current (AC) power signals power signals that control the electric starters;
- and
- a plurality of bus bars configured to directly connect the common electric starter controller to the battery and transport the DC electrical energy from the battery to the common electric starter controller, wherein the power signals are high voltage AC power signals, and wherein the electrical energy transported by the plurality of bus bars is low voltage DC electrical energy;
- a first set of electrical cables configured to carry the AC power signals to an electric starter of a first gas-turbine engine of the plurality of gas-turbine engines;
- and
- a second set of electrical cables configured to carry the AC power signals to an electric starter of a second gas-turbine engine of the plurality of gas-turbine engines.
