Drag in Accelerated Flight Solution

Follow our step by step solution on how to calculate Drag in Accelerated Flight?

FIRST Step Consider the formula

F D = T \cdot \cos (σ T) - m \cdot [g] \cdot \sin (γ) - m \cdot a

Next Step Substitute values of Variables

∴

F D = 700N \cdot \cos (0.034rad) - 20kg \cdot [g] \cdot \sin (0.062rad) - 20kg \cdot 30.37m/s²

Next Step Substitute values of Constants

∴

F D = 700N \cdot \cos (0.034rad) - 20kg \cdot 9.8066m/s² \cdot \sin (0.062rad) - 20kg \cdot 30.37m/s²

Next Step Prepare to Evaluate

∴

F D = 700 \cdot \cos (0.034) - 20 \cdot 9.8066 \cdot \sin (0.062) - 20 \cdot 30.37

Next Step Evaluate

∴

F D = 80.0429821420068N

LAST Step Rounding Answer

∴

F D = 80.043N

How to Evaluate Drag in Accelerated Flight?

Drag in Accelerated Flight evaluator uses Drag Force = Thrust*cos(Thrust Angle)-Mass of Aircraft*[g]*sin(Flight Path Angle)-Mass of Aircraft*Acceleration to evaluate the Drag Force, The Drag in Accelerated Flight refers to the aerodynamic force that opposes the motion of an aircraft as it moves through the air, it acts in the direction opposite to the aircraft's velocity vector, this equation appears to calculate the total drag force during climb flight by considering the thrust from the engines, the weight component opposing the flight path, and any additional acceleration experienced by the aircraft. Drag Force is denoted by F_D symbol.

How to evaluate Drag in Accelerated Flight using this online evaluator? To use this online evaluator for Drag in Accelerated Flight, enter Thrust (T), Thrust Angle (σ_T), Mass of Aircraft (m), Flight Path Angle (γ) & Acceleration (a) and hit the calculate button.
