Let's make a model airplane (flying object) that weighs less than 1 gram! I challenged.    1)When the weight was less than 1 gram, it was necessary to secure the speed of moveme...

    As described in "Mechanism of lift generation", since the shape of the wing is roughly plate-like, "Principle 1" becomes dominant and the influence of "Principle 2" is considerably reduc...

   Lift can be obtained even if peeled off on the upper surface of the wingMechanism of lift generation "Principle 1"     "When an object moves in the air, air is compressed o...

1, First     What kind of mechanism does lift generate on the wings of an airplane? Answers explaining the principle of this basic proposition have not yet converged to one. 　I fo...

     First, let's look at how the “object: 2D” with an elliptical cross section as shown below moves through the air. The object moving to the left, it is equal to the condition that th...

 1.Drones need wings! 　     It seems that demonstration tests of transportation systems using drones are progressing all over the world. 　      However, the...

     As drones evolve and spread in recent years, videos and illustrations that many vehicles flying in the valleys of the skyscrapers of the future have become very real and give us a ...
