Plane with retractable landing gear?

Question

who invented the first Plane with retractable landing gear? and when?

Answer 1

Great answer Eric.  Its a pity that we have to put up with idiots that just want points.

They contribute nothing, but still get the points.

All they do is show the genuine contributers that they have a very low IQ, and no self esteem.

Yes - i mean you Government Corruption and Flying Horse Girl.

Answer 2

me! yesterday!

Answer 3

J.W. Wartin's Kitten, built in 1917, had retractable gear (but could not actually fly). The Dayton Wright RB-1 of 1920 and the Verville Sperry R-3 of 1922 also had retractable gear.

The Boeing Monomail, which first appeared in 1930, and the Lockheed Orion are generally considered pioneers in the development of retractable landing gear, proving that it was practical.

For early retractable landing gear not even the performance improvements were clearly achievable, since a retractable landing gear with its motors and associated machinery weighed more than a fixed gear, thereby requiring greater lift from the aircraft and negating some of the benefits of the reduced drag of the retracted gear. While retracting the gear could improve the performance of the plane, it might require a bigger engine and more fuel—not to mention more money.

Answer 4

A design for retractable landing gear was first seen in 1876 in plans for an amphibious monoplane designed by Frenchmen Alphonse Pénaud and Paul Gauchot. Aircraft with at least partially retractable landing gear did not appear until 1917, and it was not until the late 1920s and early 1930s that such aircraft became common. By then, aircraft performance was improved to the point where the aerodynamic advantage of a retractable undercarriage justified the added complexity and weight.

Answer 5

The patent was given in 1915 but the gear wasn't installed in airplane until 1920 in the Dayton Wright  RB Racer.

Answer 6

Lockheed Orion!
