Abstract
A pneumatic start system includes a compressor system and an air turbine starter (ATS) comprising an integrated electric generator. Bleed air from the compressor system flows to the air turbine starter, exciting the integrated generator. The ATS regulates a pressure of the bleed air from the compressor system via the integrated generator. The ATS is fluidly coupled to an environmental control system (ECS) bleed system. A fluid connection between the ECS bleed system and the ATS is regulated by a starter air valve (SAV). A second connection between the ECS bleed system and the ATS is regulated by an ECS shut off valve. Pressure regulated fluid flow from the compressor system is delivered to the ECS bleed system via the second fluid connection or is delivered to ambient atmosphere, via a valve fluidly connected between the ATS and the ambient atmosphere, based upon operation of the ECS shut off valve.
