Let's say that there is a wind going 45 mph and the flight direction of the humanoid creature is in the same direction as the wind. As the flight is in the same direction as the wind, air resistance is minimum, so small it is basically 0. And let's say that this humanoid creature has a wingspan of 5 feet(2 feet per wing + 1 foot for the body) at the arms and a wingspan of 7 feet at the legs(3 feet per leg + 1 foot for the body). And let's say that the number of arm flaps per minute is 120 flaps(so 2 flaps per second) and the number of leg flaps per minute is 60 flaps(so 1 flap per second). And let's assume that it is synchronized so that the 2 arms flap at the same time, the 2 legs flap at the same time and for every 2 arm flaps completed, 1 leg flap is completed. Let's say that every arm flap moves you 3 feet and every leg flap moves you 5 feet in no wind. This makes it easier to calculate the speed.
Mass is going to be important here as is height so lets say those measures are 120 lbs and 5 feet.
- Arm length: 2 feet
- Leg length: 3 feet
- Wind speed: 45 mph
- Arm wingspan: 5 feet
- Leg wingspan: 7 feet
- Arm flapping speed: 2 flaps per second
- Leg flapping speed: 1 flap per second
- Height of humanoid: 5 feet
- Mass of humanoid: 120 lbs
Now here are my questions:
1) Can the humanoid creature fly at all assuming his/her arms and legs don't get sore after 1 minute of flapping?
2) If the humanoid creature can fly, how fast can it fly assuming it follows the wind the whole way?
3) Is the maximum speed assuming 70 mph wind speed max for no storms anywhere close to the speed of sound at 767 mph?
You notice I am using 100% imperial measurements. That is because my Kepler Bb people use a system very similar to the imperial system but with different numbers of units equaling any given unit. They do however share some base units like inches and seconds and ounces. Once I know the answers in the imperial system, it will be easy for me to convert into the Kepler measurement system(a lot of multiplication and division but that is easy(so like I would convert mph into inches per second and then use the Kepler conversion factors to convert it into Kepler miles per Kepler hour)).
