Projects of two more reconnaissance helicopters submitted to the US Army tender

In the future, the U.S. Army may have a hard time deciding on the winner of the FARA tender for replacing decommissioned OH-58D Kiowa Warrior reconnaissance helicopters. The next project of a high-speed helicopter was presented by the American company Karem Aircraft together with Northrop Grumman and Raytheon, reports "NPlus1" with reference to Aviation Week.

Projects of two more reconnaissance helicopters submitted to the US Army tender

AR40 reconnaissance helicopter project




Karem Aircraft presented the AR40 high-speed reconnaissance helicopter project, in which it is planned to create a machine with one rotor with a pushing propeller in the rear. The design provides for a side wing, which will create part of the lifting force in horizontal flight. The developers do not provide more detailed information, claiming that the flight speed of the AR40 helicopter will be 20 percent higher than that indicated by the military in the requirements for promising aircraft.

Earlier, the American company Sikorsky presented the project of the promising high-speed reconnaissance helicopter Raider-X, created using the prototype technologies S-97 Raider. The helicopter is also presented as part of the FARA tender.


project of promising high-speed reconnaissance helicopter Raider-X


According to the developers, the latest promising high-speed helicopter Raider-X will be able to reach speeds of more than 380 kilometers per hour. The helicopter is designed according to a coaxial scheme with a propeller. The body of the helicopter is made "faceted". Thus, it is proposed to reduce the effective dispersion area. The helicopter cockpit is designed for two pilots sitting next to each other. A cargo compartment is provided at the rear of the cabin for transporting goods or transferring troops. The helicopter is 27% more than its prototype S-97.

Recall. that the U.S. Army has signed an agreement with AVX Aicraft, Bell Helicopter, Boeing, Karem Aircraft and Sikorsky to create a high-speed reconnaissance helicopter to replace decommissioned OH-58D Kiowa Warrior reconnaissance helicopters. All contest participants will have to defend the projects of new helicopters in 2020

    Let's see whose idea will be developed. High-speed helicopters need new solutions and technologies. Ours are also in search, but there are already prototypes.

      I would like to see that our promising developments do not remain at the stage of "models" that have been carried from one exhibition to another for years.

      I may not be strong in aerodynamics and aviation design, but I consider the failure of the 1st model obvious. The torque of the lifting screw is not balanced by anything, and the incoming flow from it will zero the lifting force of the wing from which they want to get 20% increase. Thought it was the basics request IMHO maybe I misunderstand something (

    AR40 is visually similar to a submarine.

    pardon me! I just can’t understand why the helicopter needs (high) speed! there is a plane on it!

      In general, a helicopter needs to not only fly vertically, but also move from one point to another. And if your flight is 30 minutes instead of an hour, will you have questions and objections?

        let's say! I flew out on a tour! speed is not needed, with such racing cars! it's a HELICOPTER! but not a fighter! I have no questions for you! you set out your point of view! I respect it! how many people, so many, and opinions! everyone will remain with OWN! OK.

          Of course, I apologize, but are you going to go on an excursion with the DB? Or suppose a variant of a medical helicopter for the prompt delivery of patients from places where there is no way to save a person and there is no airspace for aircraft? There are more than a lot of options where and how to apply such machines.

          Yes. This is a helicopter. How many of them are used for excursions? Take the airship. Slow and not so loud. For excursions, no.
          And the helicopter has long been a "fighter". And tanks and enemy manpower. And a means of delivery of any goods. From humans to anything. In the absence of aircraft GDP. And here speed is clearly only good for them.

      The plane will not land near the oil rig or at the border post on the heel.

        Yes of course! I understand! but (HELICOPTER-HALF WING) how not to call him, must fulfill multifunctionality! Haste (speed) is not always a priority! for all extreme cases you need your own approach-technique! but from a helicopter do a racing car! this is a bust (my opinion) I do not know!

          When it comes to life and death specifically yours, questions about the maximum LTX technology where you are by yourself will disappear.

            again! this is not a racing car! if he (the helicopter) is given greater speed! MEAN! he will lose something! will not find the GOLDEN middle, with current technology! why planes do not freeze! and can’t fly at an EXTREMELY LOW speed! this is not given to them! this (technology) is the question, why! life and death! beside! not technology dependent!

      The meaning is very simple - the higher the speed, the less helicopters are needed to cover a certain territory in a certain time.

        it can do a plane! just do not, about INFRASTRUCTURE.

    They should be called rotorcraft rather than helicopters, since horizontal thrust is created not by the rotor, but by the thrust.

      There are no wings, what kind of "wing" is it? laughing
