Space Ranger (device)
The Space Ranger was a propane-fueled vertical take off personal transporter, similar to a platform jet pack, developed by Richard Timewell, a Seattle sheet metal worker based in a small office at Boeing Field. The transporter was advertised in several issues of Popular Science magazine during 1977–1978. United Press International's Seattle bureau on April 10, 1978, issued an article including an interview with Timewell, who stated that only one completed Space Ranger had been sold, and that he was "working out a few bugs" after hitting trees and starting fires.The Register-Guard ''The Register-Guard'' is a daily newspaper in the northwestern United States, published in Eugene, Oregon.

Propane
Propane () is a three-carbon alkane with the molecular formula . It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation. Discovered in 1857 by the French chemist Marcellin Berthelot, it became commercially available in the US by 1911. Propane is one of a group of liquefied petroleum gases (LP gases). The others include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof. Propane has lower volumetric energy density, but higher gravimetric energy density and burns more cleanly than gasoline and coal. Propane gas has become a popular choice for barbecues and portable stoves because its low −42 °C boiling point makes it vaporise inside pressurised liquid containers (2 phases). Propane powers buses, forklifts, taxis, outboard boat motors, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Take Off
Takeoff is the phase of flight in which an aerospace vehicle leaves the ground and becomes airborne. For aircraft traveling vertically, this is known as liftoff. For aircraft that take off horizontally, this usually involves starting with a transition from moving along the ground on a runway. For balloons, helicopters and some specialized fixed-wing aircraft (VTOL aircraft such as the Harrier and the Bell Boeing V22 Osprey), no runway is needed. Horizontal Power settings For light aircraft, usually full power is used during takeoff. Large transport category (airliner) aircraft may use a reduced power for takeoff, where less than full power is applied in order to prolong engine life, reduce maintenance costs and reduce noise emissions. In some emergency cases, the power used can then be increased to increase the aircraft's performance. Before takeoff, the engines, particularly piston engines, are routinely run up at high power to check for engine-related problems. The airc ...

Jet Pack
A jet pack, rocket belt, or rocket pack is a device worn on the back which uses jets of gas or liquid to propel the wearer through the air. The concept has been present in science fiction for almost a century and became widespread in the 1960s. Real jet packs have been developed using a variety of mechanisms, but their uses are much more limited than their fictional counterparts because of the challenges of the Earth's atmosphere, gravity, the low energy density of utilisable fuels, and the human body not being suited to flight, and they are principally used for stunts. A practical use for the jet pack has been in extra-vehicular activities for astronauts because of the apparent weightlessness and lack of friction-creating atmosphere in orbit. The term jet suit is used for a system incorporating a jet pack and associated jets attached to the arms to increase manoeuvrability (e.g. the Daedalus Flight Pack). Overview In the most general terms, a jet pack is a wearable device whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing Field
Boeing Field, officially King County International Airport , is a public airport owned and operated by King County, five miles south of downtown Seattle, Washington. The airport is sometimes referred to as KCIA (King County International Airport), but is not the airport identifier. The airport has scheduled passenger service operated by Kenmore Air, a commuter air carrier, and was being served by JSX with regional jet flights; however, it is currently mostly used by general aviation and cargo. The airfield is named for the founder of Boeing, William E. Boeing and was constructed in 1928, serving as the city's primary airport until the opening of Seattle–Tacoma International Airport in 1944. The airport's property is mostly in Seattle just south of Georgetown, with its southern tip extending into Tukwila. The Airport covers , averages more than 180,000 operations annually, and has approximately 380 based aircraft. History Boeing Field was Seattle's main passenger airpor ...

Popular Science
''Popular Science'' (also known as ''PopSci'') is an American digital magazine carrying popular science content, which refers to articles for the general reader on science and technology subjects. ''Popular Science'' has won over 58 awards, including the American Society of Magazine Editors awards for its journalistic excellence in 2003 (for General Excellence), 2004 (for Best Magazine Section), and 2019 (for Single-Topic Issue). With roots beginning in 1872, ''Popular Science'' has been translated into over 30 languages and is distributed to at least 45 countries. Early history '' The Popular Science Monthly'', as the publication was originally called, was founded in May 1872 by Edward L. Youmans to disseminate scientific knowledge to the educated layman. Youmans had previously worked as an editor for the weekly ''Appleton's Journal'' and persuaded them to publish his new journal. Early issues were mostly reprints of English periodicals. The journal became an outlet for writin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Press International
United Press International (UPI) is an American international news agency whose newswires, photo, news film, and audio services provided news material to thousands of newspapers, magazines, radio and television stations for most of the 20th century. At its peak, it had more than 6,000 media subscribers. Since the first of several sales and staff cutbacks in 1982, and the 1999 sale of its broadcast client list to its main U.S. rival, the Associated Press, UPI has concentrated on smaller information-market niches. History Formally named United Press Associations for incorporation and legal purposes, but publicly known and identified as United Press or UP, the news agency was created by the 1907 uniting of three smaller news syndicates by the Midwest newspaper publisher E. W. Scripps. It was headed by Hugh Baillie (1890–1966) from 1935 to 1955. At the time of his retirement, UP had 2,900 clients in the United States, and 1,500 abroad. In 1958, it became United Press I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Register-Guard
''The Register-Guard'' is a daily newspaper in the northwestern United States, published in Eugene, Oregon. It was formed in a 1930 merger of two Eugene papers, the ''Eugene Daily Guard'' and the ''Morning Register''. The paper serves the Eugene- Springfield area, as well as the Oregon Coast, Umpqua River valley, and surrounding areas. As of 2016, it has a circulation of around 43,000 Monday through Friday, around 47,000 on Saturday, and a little under 50,000 on Sunday. The newspaper has been owned by The Gannett Company since Gannett's 2019 merger with GateHouse Media. It had been sold to GateHouse in 2018. From 1927 to 2018, it was owned by the Baker family of Eugene, and members of the family served as both editor and publisher for nearly all of that time period. It is Oregon's second-largest daily newspaper and, until its 2018 sale to GateHouse, was one of the few medium-sized family newspapers left in the United States.

Aircraft Configurations
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-a ...

Ultralight Aircraft
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight". During the late 1970s and early 1980s, mostly stimulated by the hang gliding movement, many people sought affordable powered flight. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulations. The resulting aeroplanes are commonly called "ultralight aircraft" or "microlights", although the weight and speed limits differ from country to country. In Europe, the sporting (FAI) definition limits the maximum stalling speed to and the maximum take-off weight to , or if a ballistic parachute is installed. The definition means that the aircraft has a slow landing speed and sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
