This equipment is devoted to Indian Air Force for acquiring data from FDR of
Mirage-2000 aircraft and storing it for further analysis. This helps in knowing
different flight parameters to monitor the health of the aircraft in between sorties
at any given point of time and a detailed analysis can be carried out at a later
stage. This Equipment provides flight information during flight, storage of recorded
information in case of a flight accident and enables post flight processing of flight
information on the ground.
This system is primarily using for Data Acquisition, GO/NOGO Analysis (Quick
Analysis), Standard Calibration Analysis and User’s specified specific Analysis like
Flight Profile, Combat Sortie, Statistical Analysis. It also provides Graphical Plot
and Tabular Printout of data.
This equipment provides storage of recorded information and enables post flight processing of flight information on ground in order to be further used for
• Evaluation of piloting techniques • Assessment of Aircraft system operational status. • Study of flight data and equipment parameters for estimation of aircraft
reliability & development of safety methods. • Investigation of flight accidents / incidents

FLIGHT DATA ANALYSIS & ACQUISITION SYSTEM
With the disintegration of USSR into a number of region (Russia and Uzbekistan
etc) few years back the supplies of spares and test equipments to the IAF for their
Russian fleet (which is a large portion of their operational fleet) dwindled. It made
IAF to look for Indigenisation of Russian made spares and test equipment. One of
the requirements was to indigenize the milking device for Flight Data Recorder of
Russian series of aircrafts like MIG-21, MIG -27, MIG-29, AN-32 and IL-76
aircrafts. Along with indigenization, many new features like Quick Analysis,
Detailed Analysis of Milked Data and Combat Sortie Simulation were added to
improve upon the existing product.
In 1999-2000 AEM took up the development of FDAAS for MIG-27 and MIG-29
aircrafts. In 2000-2001 it took up the development or FDAAS for AN-32 aircraft.
The present products are outcome of this development. We will now be
customizing it for IL-76 aircraft.

DIGITAL AXLE COUNTER
Indian Railways is presently using analog type axle counter for signaling
applications. With the increase in rail traffic with time, it requires more precision
equipment for signaling purpose to avoid a mishap. With the revolution in
Electronic and Information Technology industry, Micro Controller / Microprocessor
Based Digital Axle Counter become a necessity in present scenario. Therefore,
Indian Railways have decided to change the present Analog Axle Counter with
Digital Axle Counter. These Digital Axle Counter are used as a track section
monitoring system. The unit is used to monitor track sections, platforms, yard
area, point zones, block section between two stations for presence or absence of
trains.
AEM has signed an MOU with Central Electronics Limited (CEL) for development
and supply of Digital Axle Counter and Central Evaluator, all the sensors along the
tracks are provided by CEL. AEM system the signals from CEL sensors, will
interface these signals to AEM Digital Axle Counters for processing.
Digital Axle Counter is trackside equipment, and counts the number of axle passes
through counters. Digital Axle Counter share the information with the next Axle
Counter, as soon as the count matches between two Axle Counters, the
corresponding track section become vacant. AEM has already developed Digital
Axle Counter, and is now under trial run.

CIRCULAR WEAVING MACHINE CONTROLLER
Lohia Machinery Manufactures an Indian company manufacturing Textile and
associated machinery having turnover of 200Cr. ($50M). In 2001-2002, Lohia
projected the requirement for Loom Controller for Circular Weaver manufactured
by them.
The Circular Weaver is used for weaving packaging fabric for bags used for packing
cement, fertilizer, agricultural and food products etc. the circular weaver consist of
three motors namely loom motor, Haul-off motor and winder motor.
The loom motor weaver weft into wrap. The haul-off motor decides the take-up
speed of the woven fabric. The haul-off motor must run at a proportional speed of
the loom motor at all times, i.e. during acceleration, de-acceleration and run
phase. The speed of the haul-off motor also decides the weft density. The winder
motor winds the produced fabric.

Machine for Textile Industry. In 1998, Lohia projected the need for Indigenisation
and upgradation of the main controller, controlling the heat processes, motor
speed and other critical inputs and outputs of the machine. Accordingly, we took
up the development of System Controller, its associated hardware and complete
software for Draw Texturising Machine. This was completed in mid 1999 and since
then we have supplied approx 20 systems, which are working satisfactorily round
the clock at various installations all over the country. Presently we are also
developing another system controller for their Loom Weaving Machine.
