The Pull-Up Maneuver Rate, or Turn Rate (ω), represents the angular velocity at which an aircraft executes a turn during a pull-up maneuver. It is expressed in radians per second and is a critical parameter in aviation dynamics.
The calculator uses the formula:
Where:
Explanation: The formula calculates the turn rate based on the excess load factor above 1g and the velocity during the maneuver, normalized by gravitational acceleration.
Details: Accurate turn rate estimation is crucial for aircraft performance analysis, maneuver planning, and understanding the aircraft's agility and structural limits during pull-up maneuvers.
Tips: Enter the Pull-Up Load Factor (must be ≥1) and the Pull-Up Maneuver Velocity in m/s (must be >0). The calculator will compute the Turn Rate in radians per second.
Q1: What is the Pull-Up Load Factor?
A: The Pull-Up Load Factor is the ratio of the lift force to the weight of the aircraft during a pull-up maneuver, indicating the g-force experienced.
Q2: Why is gravitational acceleration used in the formula?
A: Gravitational acceleration (g) is used to convert the load factor into a force difference, which then relates to the centripetal acceleration causing the turn.
Q3: What are typical values for Turn Rate in aircraft?
A: Turn rates vary by aircraft type but generally range from a few degrees per second in commercial airliners to over 20 degrees per second in fighter jets.
Q4: How does velocity affect the Turn Rate?
A: Higher velocities result in lower turn rates for the same load factor, as the centripetal force required for turning is spread over a larger distance per unit time.
Q5: Can this formula be used for other types of maneuvers?
A: While derived for pull-up maneuvers, the principle can apply to other coordinated turns where load factor and velocity are known, though specific adjustments might be needed for different scenarios.
