Australian Gyroplane is a growing and diverse Company whose members have a wide range of interests and backgrounds. It commenced operation in 2006 for the sole purpose to aid enthusiasts who are interested in building and flying their own gyroplane. 
More importantly, we focus on people, offering the opportunity to make new aviation friends and form relationships while encouraging the sharing of information, stories and enthusiasm. This focus of communication will also be brought to you with the publication of our new magazine, Australian Gyroplane, an informative glossy magazine made available through newsagents here in Australia, New Zealand and of course by subscription. 
You don't have to be a pilot or a gyroplane owner since there are different ways to fulfil your aviation interest. For the long-time gyroplane enthusiast, we have programs and activities available that allow you to meet others with the same interests. If you have dreamt of flying, but didn't realize you could participate, we invite you to join our forum and meet members to learn more about what we have to offer. More importantly, meet others with similar interests as you. Whether you are interested in building, buying or owning a gyroplane or just enjoy being around fellow enthusiasts, Australian Gyroplane is the place for you. Australian Gyroplane features: - Informative articles, news, reviews and FAQ’s
- Up to date information from the Australian Sport Rotorcraft Association Inc.
- Gyroplane club activity and news
- Airworthy Documents
- Events from New Zealand (Across the Ditch)
- Sponsor advertisements

The Autogiro
Juan de la Cierva, an airplane designer for the Spanish Air Force, invented the Autogiro in the early 1920s. In 1929, Harold Pitcairn acquired U.S. rights to Cierva's invention and formed the Pitcairn-Cierva Autogiro Company of America. This 1930 publication from Pitcairn-Cierva claims to be "the first complete authoritative presentation of the Autogiro; what it is, what it does, and how it does it."  Read more...
| "Pitch Dampener" for Gyroplanes This article is an attempt to clear up confusion over the arguments and controversy about horizontal stabilizers, thrustlines, and gyroplane pitch stability. There appear to be many concepts about what it takes to make a gyroplane safe and stable so as to avoid pitch related accidents, including Pilot Induced Oscillations (PIO) and Bunt-Overs. (Power Push-Overs are a common term for "Bunt-Over" but are technically only a type of Bunt-Over that is caused by an unbalance high propeller thrustline that contributes to the bunt-over by propelling the nose-down pitch action of the bunt-over.)

| Gyroplane Stability Misconceptions - Part2 or the "Rest of the Story" In the previous instalment of this two-part article, we discussed five popular misconceptions about propeller thrust lines as they relate to gyroplane stability. This Part 2 discusses some other popular, but misleading gyro aerodynamics misconceptions.
While presenting a number of downsides of popular misconceptions, be assured that a proper design can actually provide gyroplanes that exhibit few or none of these downside issues. This article is just to make you aware and avoid falling into “over-confidence traps”. When designed properly, as verified by actual flight testing, gyros can present stability and transient safety margins well beyond those capable on even fixed-wing aircraft Read more... | Gyroplanes, the new generation Aerodynamic technology is changing the shape of Gyroplanes. With stability issues addressed, Gyroplane popularity is poised for resurgence It’s not your father’s Gyrocopter! Re-engineered and reborn with newly appreciated and applied technology, the venerable autogyro of the nostalgic 30’s has evolved through the old Bensen gyrocopter of our youth, beyond the backyard “gyro,” to the new generation of the practical “Gyroplanes.” Read more... |

Twist 'n' Shout In the beginning of rotary-wing flight there were autogyros. Great names such as Juan de la Cierva and Harold Pitcairn reigned, and the machines, well, they looked a little bit like the newfangled aeroplanes that were plying the skies at the time. At first they flew a lot like airplanes, too. They had tractor engines, big radials up front to pull their large tube-and-rag frames through the air, stub wings with ailerons, and tail feathers with functioning elevators to facilitate the roll and pitch control. They were not, however, airplanes.

Rotor heads and Advanced Teeter Movement.
The last 5 years I have been machining rotor heads and did a lot of research in teeter movement of the unique gyrocopter. The testing of various brands of rotor blades has been an enormous satisfaction to see, that all the new rotor blades have come a long way and perform a lot better then the early ones.

Why ROTORS Instead of WINGS When I first got into gyro copters, I had been flying fixed-wing airplanes and ultralights for many years. What attracted me to gyros was how well they handled in the wind. Steph and I had loved flying our little Quicksilver ultralights, and especially our 2-place Kolb Twinstar. But, we were often frustrated by the uncomfortable mid-day turbulence, prompting us to voluntarily limit our flying to just a few hours in the mornings and evenings on most days.

Power - Where does it all go? The rotor
A rotor, with blade tips running at about 275 mph while the rest of the machine is doing 60 mph or less, isn’t the most efficient way of flying. That’s just for the lightweights; the lead sleds can have blade tips running at 350 mph.
