NOTAR Helicopter Concept

15.3k JohnnyBoythePilot  one month ago
Auto Credit Based on JohnnyBoythePilot's Bell Helicopter Project (NON-FLYING)

Developed my non-flying helicopter model into an experimental "NOTAR" helicopter concept. And yes, this one does fly. NOTAR stands for "No-Tail-Rotor" and uses directed thrust from the turbine to turn the helicopter.

Basic controls, except VTOL+Up controls forward thrust.

I also made an "Airwolf 2.0" version but it's not finished.

    Also I uploaded my Airwolf 2.0 chopper and it features some improvements to yaw-stability in high-speed level flight.

    That sucks, but I think you might have showed me some kind of NOTAR concept awhile ago before but I forgot about it.

    I think the only draw back with NOTAR is it doesn't perform as well in hot and high conditions since it relies on the turbine fan to provide airflow to the tail.

    Well this IS my first helicopter ever made in SP so it's bound to have some issues lol. I wonder if I replace the ventral fins at the rear with actual wings could help. Oh, and I also made a tail-rotor version and it was just as unstable.

    Irrelavent because this one isn't stable at all.

    NOTAR is considered a much more stable modern platform which is why a lot of police and emergency services are buying notar copters. @DankDorito

    It's not my idea. It's a real-world system developed by MD Helicopters. And yes I already know or at least have an idea on how to make custom rotor blades using rotators, wings, and VTOL nozzles. It's just a simple build I made on the side so I didn't go all out with custom rotors.

    It's a real form of yaw-control on helicopters. It was successfully developed by McDonnell Douglas Helicopter Systems (Now known as MD Helicopters). From what I hear it's a pretty great system.

    @DankDorito I thought of this at first but please look at his description, it wouldn’t work out in SimplePlanes but it’s his idea

    @JohnnyBoythePilot great job,
    if you want to try making diy blades (wings+rotator) you can check my attempt on it

    Nice and simple design. Flight is ok until you try yaw-ing. . . This is why helicopters need tail rotors, otherwise they spin out of control. The only practical way a helicopter can go without a tail rotor is when it has a coaxial main rotor. I highly recommend you add a tail rotor for the sake of stability.
