SUMMARY

The relationship between maximum endurance and maximum range speeds in aviation is defined by the factor 3^0.25, as established through first principles. The discussion references an article from MIT that provides insights into this derivation. It highlights the complexity of applying this relationship in real-world scenarios, particularly distinguishing between power-producing and thrust-producing powerplants. Understanding this relationship is crucial for optimizing aircraft performance.

PREREQUISITES
  • Basic principles of aerodynamics
  • Understanding of endurance and range in aviation
  • Familiarity with power-producing and thrust-producing powerplants
  • Knowledge of thermodynamics as it relates to flight
NEXT STEPS
  • Research the derivation of the 3^0.25 factor in aviation performance
  • Explore the differences between power-producing and thrust-producing powerplants
  • Study the impact of aerodynamics on endurance and range
  • Examine case studies of aircraft performance optimization
USEFUL FOR

Aerospace engineers, aviation students, and professionals involved in aircraft performance analysis will benefit from this discussion.

Hello all...

I know that it can be derived, from first principles, that maximum endurance and maximum range speeds are related by the factor 3^0,25.

But I haven't been able to find a derivation. Could anyone here help...?

Thanks in advance...

I think it's different for power-producing and thrust-producing powerplants.

The link answers the OP's question about where the "magic number" came from.

But nothing about aircraft is that simple in real life.
