Transient Bleed Valve (TBV)
The EEC calculates the commanded TBV position as a function
of N2 and if the engine is in start or acceleration. The TBV
discharges HPC 9th stage air to the LPT stage 1 nozzles. The
EEC sends a command signal to the HMU. The HMU sends
servo fuel pressure to move the actuator. Two LVDTs send the
valve position data to the EEC for closed-loop control.

General Description
The high pressure turbine active clearance control (HPTACC)
system controls air from these two sources:
* HPC 9th stage bleed air
* HPC 4th stage bleed air.
The HPTACC valve mixes the air to control the thermal
expansion of the HPT shroud support. Usually, the HPTACC
system keeps the clearance between the HPT blade tips and the
HPT shroud support to a minimum. This increases the fuel
efficiency. But when the engine internal temperature is not
stable, or at high power conditions, the HPTACC system
increases the turbine clearance. The HPTACC system
increases the clearance to make sure that the HPT blades do
not touch the shrouds.
The HPTCC system has these parts:
* HPTACC valve (includes the 4th stage bleed air duct)
* 9th stage bleed air duct
* HPTACC manifold.
