PT91 M Pendekar - Part 2

SAVAN 15 Fire Control System

The SAVAN 15 Fire Control System provides
armoured vehicles a true fire-on-themove
capability with a high first-round
hit probability in all combat scenarios.
The SAVAN 15 FCS integrates all functions
required to perform firing with target
detection (including gun stabilization).
Its compact and modular design makes
it ideally suited to high-performance MBT
and IFV applications, either as original
equipment or a mid-life upgrade.
The SAVAN 15 FCS has been selected for
several programs (CR2E, T72 MP, TML 105,
PT91M, etc) for which its effectiveness has
already been proven.
The SAVAN 15 consists of the following
assemblies:
• A day/night primary gunner sight
• A fire-control computer
• A set of sensors for gun stabilization
• A set of sensors for lead-angle
computation
• A man-machine interface at the gunner
station
• A man-machine interface at the
commander station

Main characteristics
Daytime and nighttime observation under all
conditions
• Direct daytime optical channel with two
magnifications (x 2 and x10)
•Thermal imager (8 to 12μm or 3 to 5μm)
with two magnifications and electronic zoom
• Sight head fitted with wipers and window
de-icer/eyepiece de-mister
Observation at standstill and on the move
Independently stabilized line of sight
(0.05 mil) with double axis
Line of sight angular travel
• Azimuth ±7°
• Elevation -12° to +22° or -12° to +45°

Target engagement with high first-round hit
probability
Line-of-sight/line-of-fire position
measurement
• Class of accuracy 0.1 mil
Automatic measurement of boresighting
variations (static MRS)
Target-tracking-rate measurement
• Class of accuracy 0.1 mil
Laser rangefinder (1.064 or 1.54 μm)
• Range 10 km
• Accuracy ± 5 m
• Repetition rate 1 Hz mean lead-angle
computation
• Automatic introduction of all parameters
(with manual backup)
• Real-time computation
• Accuracy 0.1 mil
Vertical reference on the move
Target-aiming assistance during the firing
sequence
Second-generation firing-gate management

Positioning, orientation and navigation
Integrated GPS/inertial navigation facility
BMS compatible

Backup mode
Mechanical backup mode in case of power
supply failure
Stadimetric and ammo ballistic scales
available in the daytime optical channel for
manual lead-angle introduction

Integrated Logistics Support/
Built-in Test Equipment
• Electrical interfaces
Compliant with all 28V vehicle power
supply standards
(MIL-STD-1275A, DEF-STAN 61-5, etc)
Analog or digital interfaces to gun power
drives

• Environmental conditions and EMI/EMC
Compliant with MIL-STD-810E, DEF-STD
07-55 requirements
Compliant with MIL-STD-461C requirements

p/s Check the France's tech!!!! It surey boost PT91M fire power!

Pendekar PT-91 M-part 1

Above is PT-91E a export version of PT91, renamed from Pendekar prototype.

Pendekar or warrior is the name of Malaysia's PT91M. Such tank is selected because of its upgrade capability by the army which to ensure its effectiness in today's modern warfare.

Armor
Different approach with western tank armor which is made from Chobham armor, PT91 is equiped by 394 blocks of ERA( Explosive Reactive Armor) to denoting any direct hit anti tank missile.

According from Polish Military Institute of Armament Technology (WITU), their ERAWA can provide such proctection:

1)95 to 100 per cent protection against HEAT projectiles of the low piercing type (300 to 350 mm) such as the RPG-7

(2)65 to 70 per cent protection against HEAT projectiles and rockets of the medium piercing type (460 to 600 mm) such as the AT-4 anti-tank weapon or 125 mm BK-14M HEAT projectile

(3)90 to 100 per cent protection against EFP (Explosive Formed Projectiles) with a calibre of 100 mm

(4)Full resistance against detonation after being hit by low and medium calibre ammunition, hand and mortar grenade fragments.

(5) Full resistance against detonations caused by the burning of high temperature (up to 3,000° C) materials such as napalm.




Transmission
The ESM350 is a high performance transmission developed and volume manufactured by SESM for retrofits of T-72/T-90 type vehicles. With a power range from 600 to 850kW, it features eight speeds forward and 3 speeds reverse, an infinitely superimposed steering system and a high performance braking system. It is suitable for T-72/T-90 new series as well as for upgrading program. The integration process is very easy and preserves the original silhouette of the vehicle.(1)


Technical characteristics:


Powerpack design especially for T-72 vehicles and derivates


Manual and fully automatic power shifting


Mechanical emergency gear shift system


Electronically controlled automatic start-up clutch


Infinitely variable hydrostatic superimposed steering system


Pivot turn and neutral turn on the spot at infinitely variable speed


Integrated multi-disks service and parking brake


Power-take-off for T-72 genuine power units like dynamo-starter, air compressor etc..


Power-take-off for fan drive with fully digital speed control and cut off


Engine can started by towing the vehicle


Powerpack ESM350

Including the transmission ESM350, SESM has developed a complete powerpack suitable for the T-72/T-90 and derivates vehicles. Various engine options are available, including French, Italian, Polish or Russian diesels. ESM350 has the power of 1140hp.(2)

Main advantages in four fields:


Improved mobility, resulting of increased engine-power (up to 1140 hp) and of the automatic transmission. The increased efficiency leads to reduced waste (lower heat emissions, reduced cooling problems), reduced fuel consumption and increased operating ranges.


Improved vehicle availability due to power-pack concept. Engine, transmission and cooling system are all integrated in one single, very compact block. For maintenance purposes, the PP can be exchanged in less than one hour, even in field conditions.


Better suitability for hot climatic conditions thanks to the high performance cooling system.


Advantages for fleet availability, logistics and total operating cost thanks to the high reliability of the equipment, together with the quick PP exchange capabilit
