Injection flow was managed using a combination of bleed air shutoff valves and jet pumps to allow for extraction of 1 to 10 percent of the JT8Da#39;s ... The frequency of the injection pulses could be varied at 1 Hz increments from 30 Hz to 300 Hz ( test data was collected over a ... moving parts. The valve allows steady mass flow extraction from the core of the engine. Tests indicated that no back pressure distortion resulted from the activation of the ACE Injectors, nor, when the correct pulsinganbsp;...
