Two programs that would address the operational mobility requirement are the loins Transport Rotorcraft Program to develop an advanced transport helicopter and an advanced tiltrotor program to develop a successor to the current V-22 Osprey ("super-Osprey"~. According to briefings by representatives of the ARL and the Army aviation community (Bill, 1997; Kerr, 1997; Scully, 1998)

Even so, the aircraft providing for the operational mobility of an AAN battle force would add to the logistics burden, and might not be affordable. The aviation community has initiated a study to reduce the unit flyaway cost of the lift rolocraft from an estimated $128 million per aircraft to $47 million.

From page 66... ...
Operational mobility will be the first essential phase of the combat and logistics operations for an AAN battle force. Even with major fiscal support, the two present Army programs for transporting combat vehicles by air have little chance of providing operational mobility for a nominal AAN battle force by 2025.

From page 67... ...
The third solution is to use ground-traction vehicles. Ideally, the AAN battle force will operate with an advanced fighting vehicle weighing no more than 15 tons, but, to provide tactical mobility for the entire force, it would also employ other groundtraction vehicles weighing 15 tons or less.

Although WIG craft designed after the Caspian Sea Monster were smaller, a WIG craft that could transport 2,000 metric tons was considered feasible. The Soviets pursued WIG technology for naval and military concepts to the point of test-f~ring a missile from the Lun.

can yield some insights into the advantages and disadvantages of wheeled and tracked vehicles for AAN operations. As noted previously, a starting point for M&S of combat vehicle performance is the NRMM (North Atlantic Treaty Organization Reference Mobility Model)

From page 70... ...
Software to speed processing of obstacle information gathered by the sensors is especially important. Active suspension and some type of"ditch-ejector" would assist a wheeled vehicle in breaching minor linear obstacles.
|
From page 71... ...
The committee compared the advantages and disadvantages of future wheeled vehicles supported by the enabling technologies described above with tracked vehicles in terms of meeting AAN performance objectives, as well as in terms of reducing logistics burdens. Given the AAN objectives, the committee concluded that the Army should focus on advanced wheeled vehicles for the AAN.

From page 72... ...
At present, the principal drivers for these programs are operational and performance objectives rather than logistics. Many factors specific to each vehicle concept and its intended use in the force affect whether an unmanned vehicle will increase or decrease logistics support requirements.
|
From page 73... ...
Furthermore, this incremental approach to removing the human soldier from fighting platforms seems more realistic than unmanned vehicles for reducing logistics burdens in the AAN time frame. Over time, the general approach of subsystem automation could be extended to the automation of some of the vehicles in a platoon of vehicles (or analogous tactical unit that maneuvers and fights in close coordination)
|
From page 74... ...
Obviously, Army resources should be invested in Army-unique ground mobility requirements for UGVs rather than in duplicating the efforts of other programs on unmanned vehicles.

From page 76... ...
The IRP program includes a number of components whose names indicate their objectives: Vehicle Teleoperation Capability, Tactical Unmanned Vehicle, Robotic Ordnance Clearance System, Basic Unexploded Ordnance Gathering System, UGV Technology Enhancement and Exploitation (UGVTEE) Program, and the loins Architecture for Unmanned Ground Vehicles (DoD, 199764.

specialized vehicles for urban operations · robot vehicles as direct-f~re platforms, howitzers, air defense weapons, nonlethal weapons carriers, or countersniper vehicles Advanced capabilities required to support autonomous vehicles will vary, depending on the tasks the vehicle is required to perform. For autonomous vehicles to serve as RSTA vehicles or as direct-fire platforms, they will have to have the following capabilities: secure communications and control data compression enhanced displays for remote vehicle control autonomous path following and obstacle avoidance automatic target tracking precise real-time location and identification of friendly and enemy units and equipment, including onboard identification of Fiend or foe (TFF)

From page 78... ...
However, the mobility criteria in the NRMM are based on empirical characterizations of vehicle performance, which are significantly influenced by the characteristics of past and present vehicles. Although the NRMM's basic predictive capability for ground vehicles will require some improvements, it represents an asset that could be used effectively and built upon to assess AAN vehicle design and mobility requirements.

From page 79... ...
. Engineering models that can accurately predict speed, traction, and fuel consumption for vehicles with active suspension, all-wheel traction control, electric drive, power sources other than internal combustion engines, and a host of other advanced technologies that may be required to achieve AAN off-road mobility objectives have yet to be developed.
|
From page 80... ...
Mobility characteristics associated with active suspension and Faction control, local sensing of terrain data, and other advanced technologies for vehicle subsystems must be incorporated into the NRMM tactical mobility representation. These and other extensions to the existing NRMM will be essential for assessing the kade-offs among a wide range of concepts and technologies for AAN vehicles and advanced mobility.

From page 82... ...
The Army will also require fuel consumption models for both air and ground systems. The ground versions of these models should account for energy dissipation at the interface of tire or track with soil, interaction with terrain cultural features, effects of active suspension and traction control technologies, the performance of hybrid-electric power trains, and the effects of vehicle speed and maneuvers.

From page 84... ...
The search for new approaches to air mobility should be a joint effort; at the same time, the Army must ensure that Army requirements are fully met in the process. (This initiative pertains to reducing logistics demand for the operational mobility requirements for the AAN battle force.

Mission rehearsal mobility analyses will be essential for tactical planning and for determining logistics support requirements. A mission rehearsal capability based on mobility M&S tools can be helpful for designing supportable vehicles, forecasting fuel requirements for AAN operations, and minimizing mission logistics.
