General Dynamics United Kingdom Limited, a wholly owned subsidiary of General
Dynamics, reports that its Advanced Hybrid Electric Drive (AHED) 8x8 wheeled
test-bed demonstrator has successfully completed extended running trials in an
18 ton configuration. This is the second of three extended running trials.
General Dynamics United Kingdom Limited, in association with General Dynamics
Land Systems, was awarded a contract by Atkins Limited, the FRES Systems House (SH),
in August 2005, for the Future Rapid Effect System (FRES) Chassis Concept (CC)
Technology Demonstration Programme (TDP). FRES CC TDP is an 18-month programme
to demonstrate the readiness of electric drive technology, and to enable the SH
and MoD to better understand the challenges of integrating potential electronic
architecture solutions onto a vehicle chassis.
The General Dynamics' AHED 8x8 wheeled vehicle incorporates in-hub electric
drive and hybrid power, two key enabling technologies with the potential to
transform the design of future armoured fighting vehicles. In five months of
testing the AHED has demonstrated exceptional performance and reliability, in
both 16 and 18 US ton configurations. In the course of the TDP, the AHED has
recorded more than 3,600 km of cross-country and road running with an
availability of over 90 percent. The in-hub electric drive has proved to be
reliable across challenging terrain, in demanding weather conditions and over a
range of operational mission profiles.
With over 350 kW from the hybrid power source and independent traction control
in each wheel station, the AHED can operate in terrain that would defeat
conventional wheeled vehicles. It gives the AHED cross-country performance that
is similar to that of a tracked vehicle, but with the speed of deployment, and
economy, of a wheeled vehicle. This capability offers enormous potential for
enhanced survivability and increased tempo in combat.
The AHED is now being configured to 20 US tons for additional extended running
and mobility trials, scheduled to begin shortly. Once this trial is completed,
General Dynamics working with Team ISIS (the Consortium leading one of two FRES
Electronic Architecture TDP's) will integrate an electronic architecture into
the AHED for demonstration at the UK's Armoured Trials and Development Unit
during the second half of this year.
As part of the FRES CC TDP, General Dynamics recently provided vehicle concepts
and analysis of the utility of an AHED-based platform across a range of FRES
