Description
NR-30KP in the D-30KP engine fuel-control system
The NR-30KP is an aircraft fuel pump-regulator used in the automatic fuel-control system of the D-30KP turbojet engine. The engine is installed on Il-76 family heavy transport aircraft. The unit combines a fuel pumping section and hydromechanical regulation functions in one assembly. Its purpose is to meter and supply aviation kerosene to the engine while maintaining stable operating parameters during start, idle, acceleration, deceleration and steady power modes.
Fuel metering function of the NR-30KP pump-regulator
The main task of the NR-30KP is to dose fuel accurately for the engine combustion chamber. The pump-regulator changes fuel delivery according to the engine control lever position, rotor speed, pressure conditions and automatic control commands. Correct metering is critical during engine start and acceleration, where too little fuel may prevent the engine from reaching the required mode, while excessive delivery may lead to overtemperature, unstable combustion or exceeding operating limits.
NR-30KP as part of the engine automatic control system
The NR-30KP operates as part of the D-30KP engine automatic control system. It works together with related units such as the RPPO-30KP constant-speed drive regulator, DPO-30KP reduced-speed sensor, TsR-1-30K centrifugal regulator and TsNA-30K guide vane actuator cylinder. These units support fuel metering, rotor speed control, compressor guide vane movement and engine protection functions. Because of this, the NR-30KP should be checked as part of the full engine control chain, not as an isolated fuel pump only.
Construction and operating data of NR-30KP
According to the supplied passport, the NR-30KP has right-hand drive rotation and uses kerosene fuels T-1, TS-1 and RT, including fuel mixtures and additives permitted by the engine technical documentation. The unit is designed for fuel inlet pressure from 1.2 to 7.0 kgf/cm². Maximum fuel delivery is 70 L/min at a working pressure of 20–30 kgf/cm², and the main controlled fuel flow is supplied through the calibrated metering slot. The passport also specifies a dry mass of 39.905 kg.
Operating limits of the NR-30KP fuel unit
The NR-30KP works at high speed and in demanding engine conditions. The passport lists a maximum drive speed of 4100 rpm, with permissible short-time overspeed up to 4350 rpm for no more than 30 seconds and not more than three times during the assigned period. Fuel temperature at the pump inlet is specified from −50 to +100 °C, and ambient temperature for the unit is specified from −60 to +150 °C. These limits should be observed during testing, storage release and installation.
Installation of NR-30KP on the D-30KP engine
The NR-30KP is installed on the D-30KP engine fuel-control system and is driven mechanically from the engine accessory gearbox. The pump-regulator is connected to fuel supply, metering, control and return lines according to the engine installation scheme. During installation, the drive interface, shaft condition, fittings, seals, mounting surfaces, fuel ports and control linkages must be checked carefully. Incorrect installation or contamination in the fuel ports can affect metering accuracy and engine response.
NR-30KP and Il-76 application
The NR-30KP is intended for installation on D-30KP engines, including D-30KP Series 2 engines according to the passport note. These engines are used on Il-76 aircraft family platforms. The pump-regulator is part of the engine-mounted fuel equipment group and works together with other fuel-control and compressor-control units. The exact version, installation conditions and adjustment data must be confirmed by the product passport, D-30KP engine documentation and aircraft maintenance documentation.
Supply, repair and inspection of NR-30KP
For procurement or repair, the full designation NR-30KP / НР-30КП should be used. The uploaded passport identifies the product as “Насос-регулятор НР-30КП” with passport form 3055 PS. The unit may be supplied new, from storage, repaired, overhauled or bench-tested depending on availability. Before installation, it should be checked for documentation, conservation status, drive condition, housing integrity, fuel port cleanliness, seals, adjustment points, leakage traces and bench-test compliance.
