The future digitised battlefield where helicopter crews are able to control a force of unmanned aerial vehicles has been outlined in a Boeing briefing on the future growth of the Apache AH-64D Longbow attack helicopter.
Boeing has already demonstrated the concept of UAV connectivity as part of its bid to secure funding for a Block III upgrade to the Apache, which is targeted for 2006.
A similar capability is also planned for the Boeing Sikorsky RAH-66 Comanche, which would allow unprecedented co-ordination of airborne assault forces in future combat missions.
Faster
As part of the Aviation Applied Technology Direct-orate's Hunter Stand-off Killer Team technology demonstration, AH-64Ds will team with UAV ‘wingmen' to improve targeting and situational awareness. The key is to establish connectivity with UAVs without significant increases in pilot workload.
US Army AH-64 programme manager Col Ralph Pallotta says the army's overall goal is a ‘lighter and faster' inventory and the aim is to position the Apache as the ‘bridge' to the Objective Force.
"The Apache is going to be around for at least another 25 years," says Pallotta, "and that means we must look constantly for ways to keep the aircraft at the forefront of attack helicopter technology."
Enhancements
If funded, the Block III upgrade will include a package of enhancements in addition to UAV connectivity. A main rotor upgrade featuring composite blades will be carried out, alongside re-engining with the GE T700-701D.
Improvements to the Longbow fire control radar will also be undertaken. The challenge is to achieve a 50% increase in range, a greater set and better classification of targets.
The Block III package also features improved systems architecture and flexible digital communication as well as an advanced health and usage monitoring system.Looking even further ahead, Boeing has already outlined a Block IV upgrade, dubbed the AH-64X, which would begin in 2011. This features a five-blade main rotor, fly-by-wire flight controls and a composite tail section.
The centrepiece of the plan is an all-new 2,235kW (3,000shp) turboshaft which would be developed under the Common Engine Programme (CEP).
