The Fairey Jet Gyrodyne was a British experimental compound autogyro built by the Fairey Aviation Company that incorporated helicoptergyrodyne and autogyro characteristics. The Jet Gyrodyne was built specifically to develop the pressure-jet rotor drive system and operational procedures used on the later Rotodyne.
The Alvis Leonides nine-cylinder radial engine was situated in the middle of the fuselage and drove a pusher propeller at the tip of each stub wing and two Rolls-Royce Merlin engine superchargers. The original three-blade tilting hub rotor system was replaced by a two-blade rotor controlled with swashplate-actuated cyclic and collective pitch controls. An empennage provided the necessary stabilization about the pitch and yaw axes. For takeoff, landing, and low-speed flight, the rotor was driven by air delivered by the superchargers and burnt with fuel in blade-tip mounted pressure-jets.
This zero-torque rotor drive did not require a compensating anti-torque system, though the collective pitch of the wingtip-mounted propellers was controlled by the rudder pedals to provide yaw control. As airspeed was gained, the rotor drive system was shut down, allowing the rotor to autorotate while the propellers provided the necessary thrust.
For low-speed flight and landing, the rotor drive system was restarted to provide hovering capability. Tethered flights at White Waltham were followed by the first free flight in Januarybut a full transition from helicopter to autogyro flight was not achieved until Marchpiloted by John N. System proving continued and by Septembertransitions and autorotative landings had been completed.
Development of inflight rotor drive restart procedure resulted in several power-off autorotational landings until the method was perfected. The Jet Gyrodyne was underpowered and could carry sufficient fuel for only 15 minutes of flight; on occasion external fuel tanks were carried to increase endurance.

Fairey Aircraft since Annapolis, Maryland: Naval Institute Press, Winchester, Jim, ed. Fairey aircraft. Bell In the s Bensen Aircraft Corporation exploded upon the sport aviation scene with their ground-breaking "Gyrocopters" and "Gyrogliders. Igor Bensen, introduced the B-7 Gyrogliderits unprecedented simplicity of design and ease of flight captured the public's imagination.
Although the B-7 had no engine and was towed into the air very much like a kite, shortly thereafter the engine-powered B-7M Gyrocopter was introduced and a new age of powered homebuilt aircraft dawned. Bensen's revolutionary designs have been copied and modified, but, in the opinion of many, never surpassed. Please note : Although Vortech has available reproductions of the manuals and prints for the Bensen Gyros, these materials are not sold for the construction from scratch of one of these aircraft since Bensen Aircraft is no longer in business and the technical support for safe operation is not available.
The manuals and prints are only sold to individuals that own one of these aircraft and need these reference materials. The listings for Bensen materials are at Vortech Books.
The B-8M GyroCopter The B-8M was the latest of the Bensen gyroplanes and it remains among the finest craft of its kind The gyroplane or "gyrocopter" or simply "gyro" is essentially a helicopter-airplane hybrid, offering many of the benefits of both and several of its own. Many consider it among the safest aircraft you can fly. A major safety feature of the gyro is that if the engine fails, the craft can be easily glided to a safe landing.
Also, the gyro is less affected by high wind than typical fixed-wing aircraft and is not subject to stall. The unpowered B-8 Gyroglider below falls in the class of unpowered gliders and requires no license. Of course, proper training is an absolute necessity for the safe operation of any aircraft, whether ultralight or experimental.
The above 2 aircraft are the unpowered Bensen B-8 Gyrogliders, which were towed into the air by an automobile or, if fitted with floats, by a boat. Once airborne, the cable was released and, with proper skill and perhaps some help from the wind, the craft could continue its flight for many minutes. Once control of the glider was mastered, the craft was convertible to the engine-powered gyrocopter.
Here, Dr. Bensen himself demonstrates the flying abilities of his B Once towed to an altitude of 50 to feet depending upon one's skill levelthe cable can be released for the thrill of free and open skies. Later, an engine can be added to a B-7 below drawing for completely independent flight. With a relatively modest forward tow speed by car or boat of about 23 mph, the rotorblades reached a speed of about mph, providing lift for the Glider to take-off.
The rotorblades already have a fixed, built-in pitch, so all the pilot needs to do is steer the Glider with the handlebars almost as one would steer a bike. Indeed, even with a relatively mild wind of perhaps 23 mph, the B-6 can take off and fly very much like a kite!Forums New posts Search forums. What's new New posts New profile posts Latest activity.

If you enter: jet gyro site:rotaryforum. Last edited: Nov 1, MadMuz Newbie. The trouble with using jet thrust in a gyro is that apart from being very inefficient and thirsty for a draggy slow speed machine like a gyro, due to the spool up time and run down time it would be too hard to have any accurate control over thrust It would sound awesome, but the fuel burn and lack of predictable throttle response pretty well all or nothing would never work in a gyro Turboshaft maybe, but the weight of a variable prop, the cost and complication would rule it out for most who would like to try it Probably melt the rotors at full back stick!!!!
Aussie Paul. Thank You for a better way to search for item and topics. I try not to repeat Total Flight Time stopped caring at MadMuz said:. And don't forget e grand daddy of all kerosene burning gyros, the Fairey Rotodyne. You must log in or register to reply here.A tip jet is a jet nozzle at the tip of some helicopter rotor blades, used to spin the rotor, much like a Catherine wheel firework.
Tip jets replace the normal shaft drive and have the advantage of placing no torque on the airframe, so no tail rotor is required.
Some simple monocopters are composed of nothing but a single blade with a tip rocket. Tip jets can use compressed air, provided by a separate engineto create jet thrust. Other types use a system that functions similarly to the afterburner reheat on a conventional jet engine, except that instead of reheating a gas jet, they serve as the primary heater, creating greater thrust than the flow of pre-compressed air alone; the best description of this is thrust augmentation.
Other designs includes ramjets or even a complete turbojet engine. Some, known as Rocket On Rotor systems, involve placing rockets on the tips of the rotor blades that are fueled from an onboard fuel tank. If the helicopter's engine fails, the tip jets on the rotor increase the moment of inertiahence permitting it to store energy, which makes performing a successful autorotation landing somewhat easier.
However, the tip jet also typically generates significant extra air drag, which demands a higher sink rate and means that a very sudden transition to the landing flare must occur for survival, with little room for error.
Austrian Ludwig Wittgenstein investigated the use of tip jets to drive an aircraft propeller while studying aeronautical engineering at Manchester UniversityUK and patented his ideas. The Italian designer V Isacco built "Helicogyres" in the s. Although they used piston engines at the ends of the rotary wing, he foresaw that they might be replaceable by jets. During the Second World WarGerman engineer Friedrich von Doblhoff suggested powering a helicopter with ramjets on the rotor tips.
The first tip jet-powered helicopter was the WNF V1 in The engineer who had actually produced the tip jet engines, August Stephan, joined the Fairey Aviation company of the United Kingdom which used them in their Fairey Jet Gyrodyne and Fairey Rotodyne aircraft first flying in and respectively.
Eugene Michael Gluhareff was an early pioneer of tip jets. The compressed air in cold tip jets generally exited at quite high temperatures due to compression-heating effects, but they are referred to as "cold" jets [ citation needed ] to differentiate them from jets that burn fuel to heat the air for greater thrust; similar to the difference between the "cold" and "hot" exhausts on the Harrier "Jump Jet"which uses "cold" air heated to several hundred degrees by compression inside the low-pressure compressor of the Pegasus engine.

The autogyro was invented by Spanish engineer Juan de la Cierva in an attempt to create an aircraft that could fly safely at low speeds. Burke Wilford who developed the Reiseler Kreiser feathering rotor equipped gyroplane in the first half of the twentieth century. The latter term was later adopted as a trademark by Bensen Aircraft. An autogyro is characterized by a free-spinning rotor that turns because of the passage of air through the rotor from below. A separate propeller provides forward thrust, and can be placed in a puller configuration, with the engine and propeller at the front of the fuselage, or in a pusher configuration, with the engine and propeller at the rear of the fuselage.
Whereas a helicopter works by forcing the rotor blades through the air, drawing air from above, the autogyro rotor blade generates lift in the same way as a glider 's wing,  by changing the angle of the air  as the air moves upwards and backwards relative to the rotor blade.gyrocopter hit by rotator jet stream in kav.crizalebikeling.pw
Because the craft must be moving forward with respect to the surrounding air in order to force air through the overhead rotor, autogyros are generally not capable of vertical takeoff except in a strong headwind. Pitch control is achieved by tilting the rotor fore and aftroll control by tilting the rotor laterally. A rudder provides yaw control. On pusher configuration autogyros, the rudder is typically placed in the propeller slipstream to maximize yaw control at low airspeed but not always, as seen in the McCulloch J-2with twin rudders placed outboard of the propeller arc.
There are three primary flight controls: control stick, rudder pedalsand throttle. Typically, the control stick is termed the cyclic and tilts the rotor in the desired direction to provide pitch and roll control some autogyros do not tilt the rotor relative to the airframe, or only do so in one dimension, and have conventional control surfaces to vary the remaining degrees of freedom.
The rudder pedals provide yaw control, and the throttle controls engine power. Secondary flight controls include the rotor transmission clutch, also known as a pre-rotator, which when engaged drives the rotor to start it spinning before takeoff, and collective pitch to reduce blade pitch before driving the rotor.
Like helicopters, each autogyro has a specific height—velocity diagram for safest operation, although the dangerous area is usually smaller than for helicopters. Modern autogyros typically follow one of two basic configurations. The most common design is the pusher configuration, where the engine and propeller are located behind the pilot and rotor mast, such as in the Bensen " Gyrocopter ". It was developed by Igor Bensen in the decades following World War II, and came into widespread use shortly afterward.
Less common today is the tractor configuration. In this version, the engine and propeller are located at the front of the aircraft, ahead of the pilot and rotor mast.
This was the primary configuration in early autogyros, but became less common after the advent of the helicopter. It has enjoyed a revival since the mids. Juan de la Cierva was a Spanish engineer and aeronautical enthusiast. Inhe participated in a design competition to develop a bomber for the Spanish military. De la Cierva designed a three-engined aircraft, but during an early test flight, the bomber stalled and crashed. De la Cierva was troubled by the stall phenomenon and vowed to develop an aircraft that could fly safely at low airspeeds.
The result was the first successful rotorcraft, which he named Autogiro in His aircraft became the predecessor of the modern helicopter. Juan de la Cierva invented the modern autogyro autogiro in Spanish in the early s. His first three designs C.More Pictures at the Facebook. Hi Anton, John, I would like to say thank you very much for such beautiful model, great looking in the air and on ground, very smooth and stable. Anton, Hope you are well.
Here is yet another maiden. Below is a video of my beautiful Skymaster F Another amazing masterpiece. This plane is a must have! Love the handling of this aircraft. Thank you Amir. It flew amazing.
Xenon Ultralight Gyrocopter
Another awesome bird in my collection. I am addicted to your amazing creations. Keep them coming! My friends and I are truly appreciative of what you have done for this hobby. Markus mailto:markus tankverschluss. Thank you Skymaster for your brilliant Jets!!!
Anton, Just wanted to let you know that we had the maiden flight for this beautiful F14 yesterday. It was flawless. We are all in love with this aircraft.
Skymaster did an awesome job yet again.Combine a FIAT e with an autogyro and you get the Cavalon, a two-seat, side-by-side, relatively quiet electric flying machine. Both use the same Bosch motor and inverter. Compact like the cars and autogyro it drives, the motor gets its designation from its millimeter diameter, a little over seven inches, and millimeter length 4. Bosch, like Siemens, seems intent on covering a range of electric vehicle needs.
For now we share the same challenges for endurance as the automotive industry but in time, this will increase from the current 45 minutes and the future will become the present.
The video is a year old and depicts a flight in a Rotax-powered Cavalon, but shows off the roomy cockpit and excellent visibility to advantage. Autogyros are also capable of autorotating down to a small landing space. Its roomy cockpit will allow occupants to enjoy the view at its kilometers per hour 90 mph cruise.
An Electric Autogyro
Clean lines of Cavalon autogyro lend themselves to electric flight. Since its foundation inthe ultra-light aircraft specialist has enjoyed constant growth and now has a team of highly qualified specialists and engineers. With a global network of distributors in over 40 countries, AutoGyro aims to deliver unlimited and safe flying enjoyment to its clients with the versatile gyroplanes.
If the Bosch powerplant lives up to its goal for this application, gyrocopters could become much quieter in the near future. By my calculations on useful load of a Rotax-powered Cavalon and weight of the Bosch electric powertrain vs a Rotax ULS, a Bosch-powered eCavalon should have capacity for a lb battery pack and still provide the lb useful load for pilot, passenger, and baggage featured by a Rotax-powered Cavalon with full fuel.
Interesting that the proof-of-concept eCavalon has only half the flight endurance of the Alpha Electro with identical battery weight capacity and same Kokam battery tech. Also, the eCavalon might not have as much battery capacity despite the ability to carry the same lb of batteries. It is an excellent resource for those wanting additional technical information beyond the news presented in the CAFE Blog. My name is Raymond. Iam a would be gyrocopter flyer. Has anyone considered the amassing Phinergy battery.
Basically, a battery that extends the electric or hybrid car up to Kim on a single charge. Please, only positive feedback. I have chosen to focus on positive energy. I would be grateful if someone could explain with the maths attached. Your email address will not be published.
