Detailed description of D-436 engine family

D-436T1

Type	Bypass turbofan engine.
Fan	1-stage, axial, with a booster stage.
LP Compressor	6-stage, axial.
HP Compressor	7-stage, axial.
Combustion Chamber	Annular, with 18 air-blast nozzles, 2 igniters.
HP Turbine	1-stage.
LP Turbine	1-stage.
Fan Turbine	3-stage.
Reverser	Bucket-type thrust reverser with deflecting cascade vanes. Installed in bypass duct.
Jetpipe	Separate exhaust streams.
Control System	Electronic and hydropneumechanical.

The multi-purpose engine mount allows to install engines both in nacelles on both sides of the fuselage (Tu-334 ) and in nacelles above wing (Be-200 ), in the nacelle on both sides of the fuselage and central power plant (Yak-42D-100 ) and in underwing nacelles (An-148 ).

The engine modular design and highly developed monitoring and diagnosis system ensures its on-condition operation. The engine consists of 14 modules.

01 - Fan rotor wheel
02 - Fan casing with stator vanes
03 - Fan shaft with bearing support
04 - Booster stage module
05 - Low-pressure compressor
06 - Gearbox
07 - Rear bearing support
08 - Fan turbine

09 - LPT rotor
10 - Turbine bearing supports housing
11 - HPT rotor
12 - Combustion chamber with HPT nozzle vanes
13 - Main module
14 - Thrust reverser with movable fairing

(this module is not available in D-436TP engine)

The basic engine with a takeoff thrust of 7500 kgf. 03.09.1993 – bench tests started. 08.02.1999 – Tu-334 maiden flight. In 2000 it passed type tests and was awarded with AR MAK Type Certificate. 4 units of engine are currently in operation. Total flight time is more than 2500 hours.

D-436TP:

The maritime D-436TP engine version with a takeoff thrust of 7500 kgf. Corresponding design and technological anti-corrosion efforts were introduced to ensure a safe operation at sea climate. 27.06.1995 – bench tests started. 24.09.1998 Be-200 maiden flight. In 2000 it passed type tests and was awarded with AR MAK Type Certificate. In 2006 EASA started a process of the D-436TP engine certification to JAR-E standards. 10 units of engine are currently in operation. Total flight time is more than 2500 hours.

D-436T2:

The improved D-436T1 engine version with a takeoff thrust of 8200 kgf. As to its design profile the engine is completely unified with the D-436T1 engine. The engine thrust is increased by increasing a HPT inlet gas temperature. The engine is designed to power Tu-334-200 aircraft.

D-436T3:

The improved D-436T1 engine version with a takeoff thrust of 9400 kgf. The engine thrust is increased by increasing a turbine inlet gas temperature (similar to D-436T2 engine version), by introduction of wide-chord shroud platform-free noiseless fan (without booster stage) and LPC stage “0”. The engine is designed to power Tu-230 aircraft.

D-436-148:

The improved D-436T1 engine version with a takeoff thrust ranged from 6400 to 6830 kgf (depending on control system adjustment according to variant of application). As compared with the D-436T1 the engine features improved accessory gearbox and thrust reverser, core fairing and main jet are of composites with noise-suppressing coatings, and are shorter by length. A new control system is of FADEC type. 30.03.2004 - bench tests started. 17.12.2004 An-148 maiden flight. The first two units of An-148 aircraft are under type tests now.

AI-436T12:

The improved D-436T1 engine version with a takeoff thrust of 12000 kgf. The AI-436T12 (earlier known as D-436TX), which is a logical development of the family, comprises the most conservative and complex section of the engine - the core of the earlier engine versions developed in production at domestic plants, with a development of a fan spool of a new generation and prospective configuration of a bypass turbofan with a superhigh bypass ratio. A new control system is of FADEC type.
