The Cierva C.1 was an experimental autogyro built by Juan de la Cierva in Spain in 1920, the forerunner of his successful series of autogyros. The C.1 was created by taking the fuselage from a Deperdussin fixed-wing aircraft and mounting two rotors shaft above it. This shaft carried two coaxial contra-rotating rotors, and atop it a fin for increased lateral stability. When tested, the C.1 refused to take off, which Cierva attributed to interference between the two sets of rotors leading to each set autorotating at a different speed. He considered the possibility of mechanically linking the rotors, but dismissed the idea on the grounds of weight and complexity, and his subsequent efforts would all feature single main rotors. Despite its failure to fly, the C.1 demonstrated the principle of autorotation in a full-sized aircraft for the first time, as it was taxied around the ground.

The cierzo is a strong, dry and usually cold wind that blows from the North or Northwest through the regions of Aragon, La Rioja and Navarra in the Ebro valley in Spain. It takes place when there is an anticyclone in the Bay of Biscay and an low-pressure area in the Mediterranean Sea.It is known since ancient times, and its name stems from the Latin word circius, which probably came from an Iberian word. Cato the Elder described it in the 2nd century BC as "a wind that fills your mouth and tumbles waggons and armed men." It reaches a speed of more than 100 km/h several times each year. Its maximum recorded speed has been 160 km/h in July 1956. It is more usual in autumn and winter, when larger pressure gradients take place, but a small pressure difference along the Ebro valley is sufficient to initiate a cierzo wind in any season.The cierzo wind is similar to the mistral of the Rhone valley in France or the bora in the Balcans.

The de Havilland C.24 was a two-seat autogyro built by de Havilland at its Stag Lane works in England in 1931, using a Cierva rotor head coupled to the cabin of a de Havilland DH.80A Puss Moth, and driven by a 120 hp Gipsy III engine. It was withdrawn from use by December 1934.A single example (G-ABLM) was produced and is part of the Science Museum collection. In 2008 it was on loan to the Mosquito Aircraft Museum at Salisbury Hall, near London Colney in Hertfordshire.

The Cierva C.4 was an experimental autogyro built by Juan de la Cierva in Spain in 1922 which early the following year became the first autogyro to fly successfully. The failures of De la Cierva's previous designs, the C.2 and C.3, had led him to understand that he needed to overcome the problem of dissymmetry of lift in order to get an autogyro to fly without rolling over. He noted that the problems that he was experiencing with his full-size aircraft were not found in the models that he had successfully flown, and considered the difference between the full-size and small-scale rotors. De la Cierva noted that the rotors used on his model were made of bamboo, and were thus far more flexible than the ones on his full-size aircraft. While attending an opera he realized that the flexibility reduced the moments acting on the hub and eliminated instability. Trained as a civil engineer, Cierva was aware that an otherwise cantilever structure hinged to its attachment point also generated no moment, and he designed a rotor the blades of which were mounted to the hub through hinges to permit their vertical oscillation.The C.4 used a fuselage taken from a Sommer monoplane (possibly recycled from the C.3) fitted with a four-blade rotor. It was completed around April or May 1922, and was tested from June onwards by Jose Maria Espinosa Arias at Getafe. Success was not immediate and de la Cierva undertook a long series of modifications and refinements to the design. Finally, in January the following year, the aircraft flew at Getafe, under the control of Alejandro Gomez Spencer, making a flight of some 180 metres (600 ft). Sources differ as to whether this event took place on 9 January or 17 January.On 20 January, the engine failed in flight, and the C.4's nose pitched sharply upwards. De la Cierva's original interest in autogyros - that of air safety - was dramatically vindicated when the machine autorotated to the ground completely undamaged. Two days later, De la Cierva demonstrated the aircraft to military and aero club observers, including General Francisco Echagüe Santoyo, director of the army's air service, and Don Ricardo Ikuiz Ferry, president of the Royal Aero Club Commission. This led to a military demonstration at Cuatro Vientos on 31 January, where the C.4 made a circular flight of 4 km (2½ miles) in 3½ minutes, at an altitude of over 25 m (80 ft).In July, De la Cierva built the C.5, an almost identical machine but for its three-bladed main rotor.

The Cierva CR Twin (originally designated CR LTH.1 and also known as the Grasshopper III) was a five-seat utility helicopter that first flew in the UK in 1969. It was a joint development between Cierva Autogiro Company and Rotorcraft now a subsidiary of Cierva, based on the dynamic systems of the latter company's Grasshopper design.

The Cierva C.19 was a 1930s British two-seat autogyro, designed by Spanish engineer Juan de la Cierva. It was built by Avro as the Avro Type 620. It proved to be the most successful and widely produced of the early de la Cierva designs.

The Cierva C.6 was the sixth autogyro designed by engineer Juan de la Cierva, and the first one to travel a "major" distance. Cierva, the engineer responsible for the invention of the autogyro, had spent all his funds on the research and creation of his first five prototypes. Therefore, in 1923, he turned to the Cuatro Vientos Aerodynamics Laboratory chief, Commander Emilio Herrera, who succeeded in persuading General Francisco Echagüe, the director of the Military Aviation Aeronautics Department, to take over the second stage in the research and development of Cierva's autogyros.After several wind tunnel tests, Military Aviation built a Cierva C.6 autogyro in an Avro 504 frame. This machine, piloted by Captain Joaquín Loriga Taboada, made three flights, all of them in March 1924. One of those flights, the eight-minute trip from Cuatro Vientos airfield to Getafe airfield (10.5 km / 7 miles), was considered a giant step for Cierva's autogyros.The Cierva C.6 prototype was fitted with ailerons mounted on two small wings, also with elevators and a rudder. This complete three-axis control scheme was needed because the pilot had only limited control over the rotor (See Helicopter rotor). Only the front propeller was powered, so this aircraft could not hover, and could lose control at low speed. The vertical axis rotor spun freely; the faster the autogyro flew, the faster the rotor would spin and the greater lift it produced.A replica of the Cierva C.6 was built to be shown in Murcia pavilion in Seville Expo '92 World's Fair. That replica can be now be seen in Museo del Aire (Spain), Cuatro Vientos, Madrid, Spain.

It was an attempt to build upon the successful Cierva C.8 design using the smaller, more streamlined fuselage of an Avro Avian IIIA as a starting point. The type was found to be underpowered, and when the first attempt at fitting a more powerful engine still did not result in acceptable performance, the design was abandoned.

It was a single seater twin rotor helicopter- the rotors were mounted side-by-side on outriggers- with a wooden frame. It was powered by a 50 hp 4-cylinder air-cooled Weir engine. Its first flight was at Dalrymple, Ayrshire, on 7 June 1938, and it is considered to have been the world's second fully practical helicopter.Pitch and Yaw control was achieved by tilting the rotor disks, roll control by differential pitch input to the rotors. Rotor thrust was controlled directly by the motor speed, which damped the response heavily.

The C.3 utilised a single, three-bladed rotor in place of the coaxial double rotor tested on the C.1. A few short hops were achieved in testing and Cierva noted a tendency for the machine to want to roll over, thus alerting him to the problem of dissymmetry of lift that he would have to overcome in order to build a successful rotary-wing aircraft. The C.3 was damaged and rebuilt four times before being abandoned without having flown, la Cierva returning to work on the C.2.

It was withdrawn from use by December 1934.A single example (G-ABLM) was produced and is part of the Science Museum collection. In 2008 it was on loan to the Mosquito Aircraft Museum at Salisbury Hall, near London Colney in Hertfordshire. In flight, it had a maximum speed of about 115 mph (185 km/h; 100 kn).
