A combustion control system and method for a turbulent jet ignition engine is presented. A controller is configured to access a trained feedforward artificial neural network (ANN) configured to model a first spark from a first ignition source and maximum brake torque (MBT) based on measured operating parameters, generate the first spark and MBT using the ANN, generate a second spark from a second ignition device, and determine a target spark timing. The ANN can be further configured to receive an input related to spark stagger.

An aeroderivative gas turbine including an air intake plenum; a compressor with a compressor air intake in fluid communication with the air intake plenum; a combustor; a high pressure turbine; a power turbine. A forced air-stream generator is arranged in fluid communication with the air intake plenum. A shutter arrangement is provided in a combustion-air flow path, arranged and controlled to close the combustion-air flow path for pressurizing said air intake plenum by means of the forced air-stream generator to a pressure sufficient to cause pressurized air to flow through the aeroderivative air turbine.

There is described a method and system for starting at least one engine from a twin engine installation having a first engine arrangement and a second engine arrangement. The method comprises receiving a first voltage level from a power source and increasing the first voltage level to a second voltage level; charging an energy storage unit having at least a first super-capacitor and a second super-capacitor to the second voltage level; selectively connecting one of the first super-capacitor and the second super-capacitor to a first power control unit in the first engine arrangement; controlling a discharge current to a first electric machine in the first engine arrangement via the first power control unit; and rotating a rotor of the first electric machine to an above engine idle speed to start a first engine of the twin engine installation.

A heated valve is provided and includes a valve body having an inlet, an outlet downstream from the inlet and a valve section fluidly interposed between the inlet and the outlet, a valve element operably disposed within the valve section to assume and move between at least a first position at which fluid communication between the inlet and the outlet is prevented by the valve element and a second position at which the fluid communication is permitted and a heating system. The heating system is in operable communication with at least one of the valve body and the valve element and is configured to melt ice that could prevent movement of the valve element between the first and second positions.
