Questions tagged [autogyro]
An autogyro, also known as gyroplane, gyrocopter, or rotaplane, is a type of rotorcraft which uses an unpowered rotor in autorotation to develop lift, and an engine-powered propeller, similar to that of a fixed-wing aircraft, to provide thrust.

Would an Autogryro/Gyrocopter with wings be safer than a normal autogyro in a negative G situation?
Typically Autogyros experiencing "negative Gs" will crash.
I wonder if an Autogyro with wings would work as a fail safe for this situation? Would it allow the pilot to recover assuming this ...

Would this concept of Autogyro/Gyroplane be efficient or practical?
First, i'm quite ignorant on aerospace engineering, so I hope I don't make too many incorrect assumptions.
If you don't know what an Autogyro/Gyroplane is, here is the Wikipedia article of it.
The ...

Can anyone identify this Autogyro?
I've found similar autogyros on the internet, but not this one. Most autogyros appear to have 2 cockpits and this autogyro only has one. Although I have matched its angle-tipped wings with other ...

Is there a way for the helicopter rotor to get its power half by wind, half by engine?
Imagine a gyroplane, if something happen mid-flight (when the plane is basically an autogyro and the engine provides no power to the helicopter rotor) and just the wind generated by forward flight can ...

What effect do urban wind conditions have on operating tiltwing aircraft and gyrocopters?
From this research it seems there are quite a lot of strong wind in suburb residential area and around high-rise buildings. High-rise buildings would also create wind tunnel effect and eddy winds.

Sub-ideal Autorotation in Rotorcraft
I have another AuRo question for you.
When a Helicopter autorotates (ideally) it is in the turbulent wake state and there is virtually no flow through the rotor disk (figure of Leishman attached). Now,...

Why do autogyros exist? [duplicate]
This question has been intriguing me for some time. In Autogyro the rotary blades merely acts as what fixed wings act in normal aircrafts to generate lift. So why not simply have a fixed wing instead ...

Is a rotocraft.
Uses an unpowered rotor for lift generation, instead of wings.
Uses a propeller for horizontal translation like an airplane.
