AVX Plane and L3 Applied sciences have revealed a sophisticated compound helicopter design with a coaxial most important rotor as their entry for the U.S. Military’s Future Assault Reconnaissance Plane program, or FARA. The service desires a high-speed, long-range "knife fighter" that shall be a religious successor to the OH-58D Kiowa Warrior armed scout helicopter and the successful rotorcraft might substitute as much as half of the service's present AH-64 Apache gunships.
The 2 firms unveiled their joint entry to coincide with the Military Aviation Affiliation of America’s 2019 Military Aviation Mission Options Summit on Apr. 15, 2019. That they had beforehand introduced that they'd submitted a design collectively in December 2018. The Military says it should think about between 4 and 6 complete designs for Section 1 of the FARA program, earlier than down-selecting two simply two opponents in 2020.
“We're extraordinarily happy to disclose the design for this crucial U.S. Military program,” Troy Gaffey, AVX CEO and Chief Engineer, mentioned in a press launch. “AVX and L3 present distinctive engineering design expertise and manufacturing experience that may present the Military with a sophisticated, deadly and inexpensive reconnaissance and light-attack platform.”
The design the 2 corporations have put ahead has apparent similarities to AVX’s earlier design work, that includes two ducted followers, one on either side of the higher fuselage, to supply ahead thrust, together with a coaxial most important rotor. The chopper has small wings close to the highest of the fuselage, in addition to rear stabilizers, too.

The official press launch didn't embrace any efficiency specifics, however the Military has made clear it's on the lookout for the FARA to have higher velocity and vary in comparison with the AH-64 Apache gunship. The newest AH-64E variant has a prime velocity of round 170 miles per hour in stage flight and a most, unrefueled vary of round 300 miles. Compound helicopters basically usually provide a lot better prime speeds over conventional helicopters and the addition of wings might help scale back the load on the rotors, providing added effectivity.
The helicopter additionally has two separate sub wings on both aspect of the decrease fuselage for shops and the idea artwork reveals it firing a Hellfire-type missile. The Military is trying to steadily substitute these weapons with the improved Joint Air-to-Floor Missile (JAGM).
The idea artwork reveals a sensor turret on prime of the nostril that would come with electro-optical and infrared cameras, in addition to a laser designator. There's a turret with a multi-barrel Gatling sort automated cannon beneath the nostril, as nicely.
This weapon could possibly be Common Dynamics’ new XM915 20mm cannon, which is an evolution of the light-weight three-barrel XM301 it developed within the 1990s for the abortive RAH-66A Comanche stealthy armed scout helicopter. The XM301 was itself a spinoff of the long-lasting six-barrel M61 Vulcan cannon and the sooner three-barrel M197 variant.
The Military is concerned with including loitering munitions, in addition to a precision-guided weapon that may operate as each a powered missile and a glide bomb, to the FARA’s arsenal, based on Aviation Week. Raytheon’s AGM-176 Griffin, which is already in widespread use within the U.S. particular operations neighborhood, in addition to on small U.S. Navy vessels, could possibly be one choice, because it already meets the multi-function standards. A wide range of different miniature air-launched munitions and drones that would work with an aircraft-mounted launcher are additionally both in service or in improvement throughout the U.S. army.
AVX and L3 say the helicopter could have a full fly-by-wire flight management system and options modular, open-architecture avionics and different mission programs to assist quickly incorporate upgrades sooner or later. This latter function is among the Military’s acknowledged necessities for FARA entrants.
The pilot and co-pilot will sit side-by-side within the cockpit, accord to the press launch from the 2 firms. Nevertheless, the Military has stipulated that any FARA design be capable to function in a pilot-optional mode, as nicely. Individually, the service is working along with the Protection Superior Analysis Initiatives Company to develop a “digital co-pilot” that would scale back psychological and bodily pressure on pilots and enhance operational effectiveness and security. You may learn extra in regards to the Aircrew Labor In-Cockpit Automation System (ALIAS) program right here.
The design may even have significant factor commonality with the compound helicopters they pitch for the opposite segments of the service’s broader Future Vertical Carry (FVL) program. This over-arching effort goals to exchange the entire Military’s helicopters and will substitute numerous different rotorcraft throughout the U.S. army. Apparently, the press launch from AVX and L3 says that their design could have folding rotors and wings that may permit it to suit inside a U.S. Air Pressure C-17 Globemaster III transport airplane and inside the hangar on an Arleigh Burke-class destroyer, the latter pointing to potential Navy curiosity within the FARA program.
AVX and L3 haven't made any particular point out about options to scale back their helicopter’s radar or infrared signatures, which the Military has additionally mentioned will probably be wanting into as a part of the FARA program. The service has additionally stipulated a necessity for a robust digital warfare suite in order that no matter FARA design it chooses, ultimately, can jam hostile radars for self-protection, in addition to find and destroy these threats to assist clear the way in which for different pleasant air belongings.
The idea artwork does present turrets that could possibly be related to a directional infrared countermeasures (DIRCM) system. These defensive programs, which you'll learn extra about extra right here, use turreted lasers to blind and confuse the seekers on incoming infrared-homing missiles.
Inclusion within the first section of the FARA program can be a serious improvement for AVX, which has been selling its superior compound helicopter designs since 2005. The corporate has labored on the Tactically Exploited Reconnaissance Node (TERN) drone as a part of a staff with Northrop Grumman within the lead. The Protection Superior Analysis Initiatives Company (DARPA) and the U.S. Navy's Workplace of Naval Analysis are operating that program collectively.
However the Military declined to pursue an providing from the corporate for the Joint Multi-Position (JMR) fly-off, which is meant to assist inform numerous Future Vertical Carry necessities. The service picked Bell’s V-280 Valor tilt-rotor and the SB>1 Defiant compound helicopter from Boeing and Sikorsky for this know-how demonstration program.
AVX additionally didn't win the Military’s Armed Aerial Scout (AAS) program, which sought a direct alternative for the OH-58D Kiowa Warrior. The Texas-based helicopter firm had provided a novel answer that will have recycled OH-58D most important fuselages and transformed them into compound helicopters with the corporate’s attribute twin ducted fan propulsion association and coaxial rotor system.
The Military in the end picked a a lot much less vital replace provide from Bell, generally known as the OH-58F, earlier than canceling the AAS program solely, ostensibly as a result of price range constraints. In the long run, the OH-58D fleet was retired outright. As an interim answer rather than the Kiowa Warriors, the Military established new Heavy Assault Reconnaissance Squadrons with a mixture of AH-64 Apaches and RQ-7 Shadow drones. The service had additionally been working to pair the gunships with the bigger MQ-1C Grey Eagle as a substitute mixture to satisfy the assault reconnaissance mission.
“The Apache is the most effective assault helicopter on the planet, however it’s not the most effective armed reconnaissance helicopter,” U.S. Military Brigadier Common Walter Rugen, head of the so-called FVL Cross-Practical Group (CFT) inside the new Military Futures Command, advised Aviation Week earlier in April 2019. “We want a smaller type issue that may cover within the radar muddle and that has attain.”
What this implies is that the Military is trying to award a really profitable deal sooner or later to doubtlessly substitute tons of of Apaches with the FARA design. The successful bidder may even be nicely positioned to win contracts to help the operation of these new rotorcraft for many years to return, in addition to the event of future upgrades. On the subject of AVX, its choice to associate with L3 was little question pushed partially by the attraction of leveraging the expertise and U.S. army connections of a serious established protection contractor with vital expertise upgrading and modifying plane for the U.S. army.
However this additionally signifies that competitors shall be particularly steep. Sikorsky is sort of sure to pitch a variant of its S-97 Raider compound helicopter, a design that's already flying and has been in flight testing for years now, making it a front-runner within the competitors.
Bell will suggest a design, as nicely, however has been tight-lipped about what it should seem like. It appears doable that this shall be a spinoff of its V-280 tilt-rotor, which can be in flight testing now. The corporate may additionally leverage the work it has accomplished on the smaller V-247 Vigiliant tilt-rotor drone.
As well as, Airbus additionally mentioned it should suggest a design derived from its world-record setting high-speed X3 compound helicopter demonstrator. The Military has additionally already rejected a proposal from MD Helicopters. This grew to become public data after the Authorities Accountability Workplace just lately disclosed that it had dismissed a protest from that firm alleging the Military had acted improperly in arriving at this choice.
With the prospect of shedding vital market share with its greatest buyer, Boeing can be engaged on a compound helicopter spinoff of the AH-64 that will provide drastically improved efficiency. It might doubtlessly submit this as an providing for the FARA competitors or pitch it as an outright different to a completely new scout helicopter.
The Military says it expects to make its last choices about who will get to participate in Section 1 of the FARA program between June and July 2019. AVX and L3's entry could possibly be up in opposition to vital competitors simply to get into this primary spherical.
