Now, in the case of the swallow, the Strouhal number is actually less than the average so it doesnât work right out of the box. For all the details, see: Estimating the Airspeed Velocity of an Unladen Swallow. In the end, itâs concluded that the airspeed velocity of a (European) unladen swallow is about 24 miles per hour or 11 meters per second.
The European Swallow (Hirundo rustica) must beat its wings 18 times per second to remain airborne (not 43 as is popularly believed). Comparing this with the average amplitude of their wing beat we come out to an average airspeed of about 11 meters per second (approximately 24 miles an hour). This is cruising speed, mind you.
