A unique bleed air environmental system has been developed for the Turbo Commander. This system utilizes air-to-air jet pumps as “flow multipliers” to reduce engine bleed flow requirements. Bleed power extraction is reduced from an unacceptably high 12% to a more reasonable 6%. The system is integrated with the original air cycle cooling system and heating is by compression heat. The jet pumps furnish a solution to the problem of high bleed power extraction common to turboprops, at a modest increase in cost and weight and at practically no decrease in reliability or maintainability.
