Early in the history of helicopter flight, it became apparent that helicopter flight crews complained of a remarkably high incidence of back pain compared to their fixed wing counterparts. Over the past 25 years, the high […]

The rotorcraft possesses the unique ability to efficiently hover. However, the complex nature of the rotor’s oscillatory loads and vibration characteristics induced on each sub system make successful rotorcraft design a challenge to accomplish. See structural […]
Introduction Recently we have discussed the type of flight control and navigation equipment that will appear in our experimental personal helicopter. Of course, there are still a few components to model like: landing skids, pilot’s seat, […]
Introduction: Today we will see what the cockpit and flight instruments of a traditional helicopter and modern units look like. What information the pilot needs for a safe flight. And ofcourse I will introduce you to […]
Intro Today once again we going to look closer to conventional helicopter build with focus on anti-torque solutions. Recently we talked about engines, controllers, airfoils types, and main rotor solutions. Same as before, we going to […]
Control Basics All conventional helicopters have the same basic controls to manipulates the helicopter flight controls to achieve and maintain controlled aerodynamic flight: Collective stick to enable power changes and vertical motion. Cyclic stick to enable turns and forward […]
Airfoil Any object, such as a flat plate, or the deck of a bridge, with an angle of attack in a moving fluid will generate an aerodynamic force perpendicular to the flow. Airfoils are more efficient lifting shapes, […]
Introduction Lastly I have presented totally new engine concept as a upcoming upgrade for personal helicopter device P01 in One Man Helicopter project for Unreal Engine 4. Based on Rotax engine technology at models 912, 914 […]
