Relative velocity or actual? If relative, to what???

Actual Ground Speed, no tail or headwind, flying against the rotation of earth......now tell me what its NES is boyo.

So, taking the average statistics and plugging them in to the Strouhal equation for cruising flight (fA/U = 7 beats per second * 0.18 meters per beat / 9.5 meters per second) yields a Strouhal number of roughly 0.13:



... indicating a surprisingly efficient flight pattern falling well below the expected range of 0.2–0.4.

Although a definitive answer would of course require further measurements, published species-wide averages of wing length and body mass, initial Strouhal estimates based on those averages and cross-species comparisons, the Lund wind tunnel study of birds flying at a range of speeds, and revised Strouhal numbers based on that study all lead me to estimate that the average cruising airspeed velocity of an unladen European Swallow is roughly 11 meters per second, or 24 miles an hour.

Good lord man WHY........... >.>

I'd like to know who ridicules someone for asking questions. Seriously. It's called "New Biker's Forum" for a reason.

I don't even have a bike yet and I lurk here asking stuff occasionally :p

Hello? Nobody's ridiculing anyone. Both the OP's and Texfire's questions had been well, truly, and seriously answered.

This is satire....... like Monty Python & the Holy Grail, y'know???

Indeed. My answer was carefully interspersed between classic Python. A threadjacking equivalent of saying, "And now for something completely different..."

Is engine braking bad for the engine, it feels like it would be terrible for it. But I believe I read or heard it was not. Just can't remember if it was a reliable source or not. Thanks
