Power required for given total drag force Solution

STEP 0: Pre-Calculation Summary

Formula Used

Power = Drag Force*Freestream Velocity
P = F_D*V_∞
This formula uses 3 Variables

Variables Used

Power - (Measured in Watt) - Power is defined as the product of thrust force and velocity of aircraft.
Drag Force - (Measured in Newton) - Drag Force is the resisting force experienced by an object moving through a fluid.
Freestream Velocity - (Measured in Meter per Second) - The Freestream Velocity is the velocity of air far upstream of an aerodynamic body, that is before the body has a chance to deflect, slow down or compress the air.

STEP 1: Convert Input(s) to Base Unit

Drag Force: 99.99 Newton --> 99.99 Newton No Conversion Required
Freestream Velocity: 30 Meter per Second --> 30 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = F_D*V_∞ --> 99.99*30

Evaluating ... ...

P = 2999.7

STEP 3: Convert Result to Output's Unit

2999.7 Watt --> No Conversion Required

FINAL ANSWER

2999.7 Watt <-- Power

Thrust Angle for Unaccelerated Level Flight for given Lift

LaTeX Go Thrust Angle = asin((Weight of Body-Lift Force)/Thrust)

Weight of Aircraft in Level, Unaccelerated Flight

LaTeX Go Weight of Body = Lift Force+(Thrust*sin(Thrust Angle))

Thrust for Level and Unaccelerated Flight

LaTeX Go Thrust = Drag Force/(cos(Thrust Angle))

Thrust Angle for Unaccelerated Level Flight for given Drag

LaTeX Go Thrust Angle = acos(Drag Force/Thrust)

Power required for given total drag force Formula

LaTeX Go

Power = Drag Force*Freestream Velocity
P = F_D*V_∞

What is the condition for steady, level flight?

In all cases, for all engines, when the aircraft is in equilibrium at steady level flight, thrust equals drag.
