But because the weight and drag of the tether increases with height, small kites don''t operate as well at 300 meters or higher, where the wind tends to be strongest. Companies want to scale up

READ MOREHigh-Speed Turbines: Utilized for cutting hard tissue and operating at speeds ranging from 300,000 to 800,000 RPM, these are indispensable for procedures like cavity preparation and crown shaping. Low-Speed Turbines: Best suited for polishing and finishing, these operate at speeds below 40,000 RPM and are used for tasks such as
READ MORESwiss start-up Skypull, for example, has developed an autonomous drone that can fly as high as 600m - about three times the height of a traditional wind turbine. Its current prototype is a rigid
READ MOREAir turbine starters are supplied by ground cart, APU, or another operating onboard engine. Only one source of around 30–50 pounds per square inch (psi) is used at a time to start the engines. The pressure in the ducts must be high enough to provide for a complete start with a normal limit minimum of about 30 psi.
READ MOREThere are several methods of getting the mechanical energy from the wind''s kinetic energy. Lighter-than-air (LTA) moored aerostats are employed as lifters of turbines. Heavier-than-air (HTA) tethered airfoils are being used
READ MOREThis new generation of systems employs flying tethered wings or aircraft in order to reach winds blowing at atmosphere layers that are inaccessible by traditional
READ MORE3 Light as a feather. You might expect this aircraft to be a very difficult one to pilot. However, Avro designed the bomber to be as easy as possible to maneuver. Those seated in this iconic aircraft''s cockpit state that the bomber was very light on the controls, and this is because the feel was artificial.
READ MOREAgain, advocates think they will likely be safer for birds than wind turbines, since the kites fly higher than birds typically do. However, the tethers themselves move quickly and are hard to see, and birds might have a hard time avoiding them. It remains unclear how widely used kite-based wind power will become.
READ MOREThe square drone shakes in the wind with the Swiss Alps in the background. At first glance, this looks like a holiday video of a drone enthusiast, except that the drone is generating energy when it flies. A cable connects it to the ground and when the wind pulls up the drone, it releases the cable through a winch, and energy is produced.
READ MOREAn aircraft''s Ram Air Turbine is a small auxiliary propellor that can be deployed in the event of a power loss. It works by generating power from the airstream passing over it as the plane flies, causing the turbine to rotate. The turbine can be connected to a generator or a hydraulic pump. This way, it can help to power either an

An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, or the need for slip rings or yaw mechanism. An electrical generator may be on the ground or airborne. Challenges include safely suspending and
READ MOREA ram air turbine driving an electrical generator was chosen for the VC10 because of its use of "packaged" hydraulically-powered flying controls, rather than a centralised hydraulic system. The individual package units of the VC10 were each powered electrically and so emergency redundancy for the VC10 relied on quadruple generators and a backup RAT
READ MORESummary. On January 27th, a Virgin Atlantic Dreamliner had to return to London Heathrow due to an inflight incident. The aircraft safely returned with its RAM Air Turbine in operation. The Dreamliner, registered as G-VZIG, was scheduled for a flight from London to Seattle. It departed 15 minutes late and halted its climb at 23,000 feet to
READ MOREFuel is mixed with the air and ignited – bang – producing the power. This hot, high-pressure air rushes past a set of turbine blades, causing them to spin. This turbine is connected by an axel to the compressor and the fan, so as the gases turn the turbine, this causes both the inlet fan and compressor fan to spin too.
READ MOREJet engines are more efficient at higher altitudes because the cold and less dense air at this altitude efficiently maximizes fuel burn. The primary reason for operating jet engines in the high-altitude environment is because it is most efficient in that environment. At high-altitude, the outside air temperature decreases for constant engine

READ MORESuch airborne wind-energy systems offer many advantages over standard wind turbines, most notably that these tethered airfoils can tap the relatively strong and steady winds found higher up. In
READ MORESimao Ferreira''s ambition is to radically change wind farms from constructions that exhaust wind resources, into ingenious systems that actively generate lift to channel wind to and from higher atmospheric regions, using momentum and energy.". This technology is expected to improve wind farm efficiency by an impressive 25-40%.
READ MOREOur ram air turbine (RAT) is at the heart of an aircraft''s emergency power system. In fact, RATs are responsible for saving more than 2,400 lives over the past five decades. If an airplane were to lose power, the RAT would deploy from the airplane''s wing or fuselage and rotates to extract sufficient power from the airstream to control and land the aircraft.
