Excess power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Excess Power = Velocity*(Thrust-Drag Force)
P_excess = v*(T-F_D)
This formula uses 4 Variables

Variables Used

Excess Power - (Measured in Watt) - Excess Power is defined as the difference between the power available and the power required at a particular speed and altitude of aircraft.
Velocity - (Measured in Meter per Second) - Velocity is a vector quantity (it has both magnitude and direction) and is the rate of change of the position of an object with respect to time.
Thrust - (Measured in Newton) - Thrust denotes the force exerted by the engine to propel an aircraft forward.
Drag Force - (Measured in Newton) - Drag Force is the resisting force experienced by an object moving through a fluid.

STEP 1: Convert Input(s) to Base Unit

Velocity: 60 Meter per Second --> 60 Meter per Second No Conversion Required
Thrust: 700 Newton --> 700 Newton No Conversion Required
Drag Force: 80.04 Newton --> 80.04 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_excess = v*(T-F_D) --> 60*(700-80.04)

Evaluating ... ...

P_excess = 37197.6

STEP 3: Convert Result to Output's Unit

37197.6 Watt --> No Conversion Required

FINAL ANSWER

37197.6 Watt <-- Excess Power

Flight path angle at given rate of climb

LaTeX Go Flight Path Angle = asin(Rate of Climb/Velocity)

Velocity of aircraft at given rate of climb

LaTeX Go Velocity = Rate of Climb/sin(Flight Path Angle)

Rate of Climb

LaTeX Go Rate of Climb = Velocity*sin(Flight Path Angle)

Weight of Aircraft for given Excess Power

LaTeX Go Aircraft Weight = Excess Power/Rate of Climb

What is excess thrust?

The thrust minus the drag of the aircraft is called the excess thrust of the aircraft and is also a vector quantity.

How to Calculate Excess power?

Excess power calculator uses Excess Power = Velocity*(Thrust-Drag Force) to calculate the Excess Power, The Excess power refers to the surplus power available to an aircraft beyond what is required to maintain level flight at a specific speed and altitude, it is particularly important during critical phases of flight, such as takeoff, climb, and maneuvering. Excess Power is denoted by P_excess symbol.

How to calculate Excess power using this online calculator? To use this online calculator for Excess power, enter Velocity (v), Thrust (T) & Drag Force (F_D) and hit the calculate button. Here is how the Excess power calculation can be explained with given input values -> 37197.6 = 60*(700-80.04).

FAQ

What is Excess power?

The Excess power refers to the surplus power available to an aircraft beyond what is required to maintain level flight at a specific speed and altitude, it is particularly important during critical phases of flight, such as takeoff, climb, and maneuvering and is represented as P_excess = v*(T-F_D) or Excess Power = Velocity*(Thrust-Drag Force). Velocity is a vector quantity (it has both magnitude and direction) and is the rate of change of the position of an object with respect to time, Thrust denotes the force exerted by the engine to propel an aircraft forward & Drag Force is the resisting force experienced by an object moving through a fluid.

How to calculate Excess power?

The Excess power refers to the surplus power available to an aircraft beyond what is required to maintain level flight at a specific speed and altitude, it is particularly important during critical phases of flight, such as takeoff, climb, and maneuvering is calculated using Excess Power = Velocity*(Thrust-Drag Force). To calculate Excess power, you need Velocity (v), Thrust (T) & Drag Force (F_D). With our tool, you need to enter the respective value for Velocity, Thrust & Drag Force and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Excess Power?

In this formula, Excess Power uses Velocity, Thrust & Drag Force. We can use 1 other way(s) to calculate the same, which is/are as follows -

Excess Power = Rate of Climb*Aircraft Weight
