POWER: 2 x Turboshaft engines of unknown make, model, and output power driving 2 x Four-bladed main rotors arranged co-axially over the fuselage; 2 x Ducted-fans for additional forward thrust.
The Future Vertical Lift (FVL) program (formerly known as the Joint Multi-Role - 'JMR' - program) is an ongoing United States military initiative to develop a complete line of related helicopters in the hopes of succeeded several high-profile - though aging - types such as the Boeing AH-64 "Apache" attack helicopter, the Bell OH-58 "Kiowa" light-class scout, the venerable Sikorsky UH-60 "Black Hawk" transport, the Boeing CH-47 "Chinook" tandem-rotor heavy-hauler. The program is highly optimistic but would completely rewrite American military rotor capabilities for most of the current century and has gained the interest of several high- and low-profile rotorcraft industry players.
AVX Aircraft Company , headquartered in Benbrook, Texas, is championing their "JMR" (Joint Multi-Role) platform for general troop / cargo transport and assault duties. The aircraft sports a streamlined fuselage that is tapered at both ends, fitting the two-crew (side-by-side seating) over a short nose assembly at front with a two-piece powered loading door at rear. Lift is achieved by way of 2 x Four-bladed main rotor units seated co-axially (one atop the other) over the fuselage and this arrangement (proving popular with many Russian Kamov helicopters) inherently cancels out torque effects of either unit - effectively negating the need for a dedicated tail rotor unit. In addition to this, the aircraft sports ducted-fans installed along the aft sides of the fuselage to provide additional forward propulsion (therefore the product is described as a "compound" helicopter). Wing stubs are positioned just over the cockpit and at each ducted fan unit for the needed horizontal flight controlling. A multi-wheeled, retractable undercarriage is planned for the aircraft.
The standard operating crew is projected to be two pilots in addition to a pair of Crew Chiefs.
The JMR can support pintle-mounted 7.62mm Medium Machine Guns (MMGs) or similar at window positions for point-suppression at landing zones (to be managed by the Crew Chiefs). Troopers can exit the hovering aircraft (via rope) from the rear-mounted loading ramp or side doors. The hold is slated to support two complete cargo palettes, up to twelve medical litters and accompanying staff, or seat fourteen combat-ready infantry along two banks of seven seats (personnel being seated face-to-face). Additionally, an external sling load up to 13,000lb can be hauled.
The JMR has also been drawn up in an attack configuration, armed through rocket pods, Anti-Tank Guided Missiles (ATGMs), and a large-caliber trainable autocannon. These appear to be managed through a retracting feature across the belly of the aircraft with four points reserved for air-launched munitions and a single point for the swiveling autocannon.
Key marketing features of the JMR include exceptional speed and range (compared to traditional helicopter designs of same class), very compact design for improved storage onboard carriers and the like, an in-built multi-role / multi-mission capability to come from a single airframe, inherently excellent low-speed maneuverability, ease of embarking / disembarking troops and cargo loads via the twin cargo doors at rear (and side doors), and broad support for in-service American military weapon and operating systems.
Currently (April 2019), the JMR is showcased with an empty weight of 18,2000lb and a MTOW of 28,000lb, a maximum speed of 236 knots, and a range out to 2,100 nautical miles.
