T-80B fuel efficiency improvements
Fuel efficiency improvement attempts among gas turbine T-80s have always been a relevant topic. In the mid-late 1980s, a field trial was conducted to test special fuel efficiency improvement systems mounted on T-80B tanks. Improved control systems and upgraded gas turbine sub-modules were present on upgraded T-80B batches. The first platoon consisted of 5 T-80B tanks, fitted with 920kW (1250hp) engines and equipped with additional upgrades. The following upgrades were present: Automatic low-gas parking mode Improved valves on the NR-1000B fuel regulator with new adjustable nozzle drives and provisioned power supply to function on low-gas parking mode (lowered fuel consumption to 45kg/h) To clarify, low gas mode is a special automatic system preset on T-80 tanks. This system reduces engine output levels and overall performance when the vehicle is stationary. It is achieved by reducing the RPMs on the 2nd cascade turbocompressor and injecting fuel only using 1 set ...
