Bicycle Aerodynamic Balance of Wright Brothers: A student project worth doing!

Image
Innovations and inventions need creativity more than other resources like money etc. Wright Brothers had made a very innovative yet a simple and cheap device to collect aerodynamic data for different shapes of Wings/Aerofoils. The Bicycle Aerodynamic Balance of Wright Brothers is shown below:- The 1901 Wright glider developed only one-third of the lift  predicted by the aerodynamic data of lift coefficients given by the legendary  German aviator Otto Lilienthal. During the fall of 1901, the brothers began to question the aerodynamic data on which they were basing their designs. They decided to measure the lift and drag coefficients themselves  and for this purpose they made two devices. The first was the bicycle aerodynamic balance and the second was the  wind tunnel .  More information on the bicycle aerodynamic balance is available on the link given below:- https://www.grc.nasa.gov/www/k-12/airplane/wrights/biketest.html

Vertical Climb

(Click on the heading 'Vertical Climb'. The post text along with the video will appear. To see the video, click on it.) (Video Courtesy, Shri Amit Jangir) In this video, a model aircraft can be seen climbing vertically. What about the Thrust to Weight Ratio of such an aircraft! Can an aircraft climb vertically upwards with a Thrust to Weight Ratio of less than 1?
