Autogyro
An autogyro (from Greek and , "self-turning"), gyroscope, gyrocopter or gyroplane, is a class of rotorcraft that uses an unpowered rotor in free autorotation to develop lift. A gyroplane "means a rotorcraft whose rotors are not engine-driven, except for initial starting, but are made to rotate by action of the air when the rotorcraft is moving; and whose means of propulsion, consisting usually of conventional propellers, is independent of the rotor system." While similar to a helicopter rotor in appearance, the autogyro's unpowered rotor disc must have air flowing upward across it to make it rotate. Forward thrust is provided independently, by an engine-driven propeller. It was originally named the ''autogiro'' by its Spanish inventor and engineer, Juan de la Cierva, in his attempt to create an aircraft that could fly safely at low speeds. He first flew one on January 1923, at Cuatro Vientos Airport in Madrid. The aircraft resembled the fixed-wing aircraft of the d ...

The brewery had its own power plant. There is an attached exhibition o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pitcairn Aircraft
The Pitcairn Islands ( ; Pitkern: '), officially Pitcairn, Henderson, Ducie and Oeno Islands, are a group of four volcanic islands in the southern Pacific Ocean that form the sole British Overseas Territory in the Pacific Ocean. The four islands—Pitcairn, Henderson, Ducie and Oeno—are scattered across several hundred kilometres of ocean and have a combined land area of about 47 square kilometres (18 square miles). Henderson Island accounts for 86% of the land area, but only Pitcairn Island is inhabited. The inhabited islands nearest to the Pitcairn Islands are Mangareva (of French Polynesia), 688 km to the west, as well as Easter Island, 1,929 km to the east. The Pitcairn Islanders are descended mostly from nine British HMS ''Bounty'' mutineers and twelve Tahitian women. In 2023, the territory had 35 permanent inhabitants, rendering it the smallest territory in the world in terms of permanent resident population. History Polynesian settlement Various f ...
