Specific Thrust given Effective Speed Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Specific Thrust = Exit Velocity*(1-Effective Speed Ratio)
I_sp = V_e*(1-α)
This formula uses 3 Variables

Variables Used

Specific Thrust - (Measured in Meter per Second) - Specific Thrust is the thrust produced per unit mass in per unit time.
Exit Velocity - (Measured in Meter per Second) - Exit Velocity refers to the speed at which gases expand at the exit of nozzle of a engine.
Effective Speed Ratio - Effective Speed Ratio is the ratio of aircraft forward speed to the aircraft jet velocity.

STEP 1: Convert Input(s) to Base Unit

Exit Velocity: 248 Meter per Second --> 248 Meter per Second No Conversion Required
Effective Speed Ratio: 0.4475 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_sp = V_e*(1-α) --> 248*(1-0.4475)

Evaluating ... ...

I_sp = 137.02

STEP 3: Convert Result to Output's Unit

137.02 Meter per Second --> No Conversion Required

FINAL ANSWER

137.02 Meter per Second <-- Specific Thrust

(Calculation completed in 00.004 seconds)
