In order to maintain safe aircraft operation, regulations for helicopter operations set by the FAA in the United States and EASA in Europe are followed. Performance Factors The most significant factors that determine helicopter performance are engine power and lift generated by the rotor. The factors t.. 2023. 5. 14. The reason why helicopter accidents occur during takeoff and landing, Ground Effects The influence exerted on a helicopter during takeoff and landing due to changes in airflow is referred to as ground effects. Ground effects involve changes in the rotor's induced angle and thrust due to variations in downwash and rotor wake. Helicopter's Ground Effects Rotor Wake Unlike fixed-wing aircraft, which generally experience relatively constant lift across the entire wing, helicopters g.. 2023. 5. 14. Flight Conditions: Helicopter Tilt for Forward Flight These are flight conditions for helicopters. Helicopters have the unique ability to hover in place, unlike fixed-wing aircraft. The conditions include forward flight, vertical movement (ascending and descending), and hovering flight (Hovering Flight). Flight Conditions for helicopters Forward Flight When observing a helicopter in forward flight, you can see that the aircraft tilts forward. Since.. 2023. 5. 14. Helicopter Rotor Aerodynamic Design Let's explore the essential aerodynamic characteristics of helicopter rotors. Like airplane wings, rotor blades are also shaped like airfoils, but there are differences in design considerations compared to airplane design. Here are some key points to consider when designing rotor systems. Components of the Rotor System The rotor system consists of a mast, hub, and rotor blades. The mast and hub .. 2023. 5. 14. 이전 1 2 3 4 5 ··· 10 다음
