WHAT IS A GYROPLANE / AUTOGIRO / AUTOGYRO / GYROCOPTER?
 
 FAQ's

 

 

"GYROPLANE" is an official term designated by the Federal Aviation Administration (FAA) USA describing an aircraft that gets lift from a freely turning rotary wing or rotor blades and which derives its thrust from an engine-driven propeller. Historically, this type of aircraft has been known as autogiro and gyrocopter. These names and their variants were filed as trademarks.

 

Gyroplanes derive lift from freely turning rotor blades tilted back to catch the air. The air-stream spins the rotor as the aircraft is thrust forwards by an engine driven propeller. Early gyroplanes were powered by engines in a tractor (puller) configuration and were relatively heavy. Modern gyroplanes use a pusher propeller and are light and maneuverable. With the engine in the rear, the gyroplane has unobstructed visibility.

 

 
WHAT IS AUTOROTATION?
 

 

Oncoming airflow going up through the rotorblades causes them to spin thus producing lift, this is called "AUTOROTATION" because the rotor is rotating freely without any engine driven power.

 
HOW IS AN AUTOGYRO / GYROPLANE DIFFERENT FROM A HELICOPTER?
 

 

An Autogyro can fly more slowly than airplanes and will not stall, they can fly as fast as helicopters but cannot hover as well without loss of altitude. Since the rotorblades on a gyroplane are powered only by the  flow of air fhrough
them much like a windmill, there is no need for a tail rotor to counter engine produced counter rotating torque. The autogyro is a very stable flying platform.  A helicopter pulls air down through the engine powered rotor blades making it possible to hover this however makes the aircraft very complicated and expensive to fly and operate. Due to the autogyro's inherent design simplicity it is easier to operate and less expensive to maintain than  the helicopter Helicopters at low altitude and out of ground effect, avoid hovering whenever possible because safe recovery from low altitude in the event of engine failure is not possible. To fix surveillance on one spot, proper procedure for all helicopters is to circle in a slow orbit maintaining forward motion in much the same way as a Gyroplane does when doing the same job.

 
HOW SAFE IS AN AUTOGYRO? WHAT HAPPENS IN CASE OF ENGINE FAILURE DURING FLIGHT?
 

A major and unique safety feature of the AUTOGYRO / GYROPLANE is that it CANNOT STALL, in the same way that a conventional aircraft can. If the engine quits the freely rotating rotor  continues to produce  lift  from the air flow  as the aircraft decends it is able to land under full control is just like a normal landing. Descending keeps the rotor turning and you can get about 3000 feet of horizontal distance for the loss of every 1000 feet of elevation. The second major safety feature of the Autogyro is that it can land like a helicopter, in a very short distance, you don't need to find a runway .

 
ARE AUTOGYROS EXPENSIVE TO OPERATE?
 

Simplicity in Gyroplane design translates directly into safety,  higher performance,  higher mission readiness, lower maintenance and a more economical and greener operation. In fact the cost of the cheapest helicopter available in the market is at nearly 3 times more than that of Autogyro. The operating cost of roughly $65 US Dollars per hour  including fuel is less than half that of the Robinson R22 helicopter and at only one third of the capital cost.

 
WHAT FUEL DO AUTOGYROS USE?
 

Gyroplanes use 80 to 225hp Turbo charged fuel injected engines and use 91-95 Octane Gasoline Premium uleaded GREEN FUEL, nowadays available almost anywhere in the world.

 
DO AUTOGYRO'S NEED AIRSTRIP OR RUNWAY FOR OPERATING?
 

Autogyros are perfect GO-ANYWHERE aircraft with VSTOL (Very Short Take Off & Landing) characteristics, they need approximately 10 to 300 metres of hard ground or grass strip to take-off and less than 5 metres to land.

 
HOW HIGH AND FAST CAN AN AUTOGYRO FLY?
 

Normally Autogyros fly at an altitudes of less than 10,000 feet ASL but they are capable of flying as high as 25,000 amsl. The VNE of the Gyroplane varies but they economically cruise at speeds ranging between 75 and 120 mph (depending upon the weather conditions and type.).

 
HOW IS AN AUTOGYRO STORED?
 

A gyroplane does not have wings, only a Rotor blade which makes it  very easy to park in small spaces. Moreover you can always tether the rotor blades in line with the main body to save space. Autogyro's are easily transported aboard Ships, vehicles and other types of transport including large aircraft for ulta quick deployment. The rotors are attached by a single bolt and can be removed or mounted in minutes.


CAN AUTOGYROS / GYROPLANES REPLACE THE HELICOPTER?     HOW ELSE CAN THEY BE USED, EXCEPT for TRANSPORTATION, SPORTS AND RECREATION?
 

Due to the ability of the Autogyro / Gyroplane to fly slow & low while making a lot less noise and consuming much less fuel and with their low maintenance they are now proving to be a very effective replacement for helicopters in the following fields -

  • Military and Para-military Operations
  • Intelligence Gathering
  • Border Surveillance and Patrolling
  • Airfield Bird Control
  • Aerial Video Surveillance, infrared and thermal imaging
  • Crowd Control & Policing
  • Oil and Gas Pipeline Inspection
  • High Voltage Powerline Inspection
  • Aerial Survey
  • Highway & Forest Patrolling
  • Agriculture Crop Spraying & Dusting
  • Locust Control
  • Cash and VIP secure transport ( we currently have two aircraft owned by a casino doing just that)
