Eli Beeding
Eli Lackland Beeding Jr. (December 17, 1928 – December 21, 2013) was a U.S. Air Force captain and rocket test subject. In 1958, a series experiments using a miniature rocket sled began at Holloman AFB under the supervision of Colonel John Stapp and Captain Beeding. Participants rode the "Daisy Sled" (so-called because it was originally designed to be air, and not rocket, powered) at various speeds and in many different positions — even head first — in an attempt to learn more about the ''g''-force limits of the human body. On May 16, Capt. Eli Beeding prepared to make a 40 ''g'' run. The Daisy shot down the track, reached a top speed around 632 mph, and came to a screeching halt in less than a tenth of a second. "When I hit the water brake," Beeding recalled in a recent interview, "It felt like Ted Williams had hit me on the back, about lumbar five, with a baseball bat." Beeding had barely informed flight surgeon Capt. Les Eason of his troubles when he began to experienc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Sled
A rocket sled is a test platform that slides along a track (e.g. set of rails), propelled by rockets. A rocket sled differs from a rocket car in not using wheels; at high speeds wheels would spin to pieces due to the extreme centrifugal forces. Apart from rare examples running on snow or ice (such as Max Valier's RAK BOBs of the late 1920s and Harry Bull's BR-1 in 1931), most rocket sleds run on a track. Although some rocket sleds ride on single beams or rails, most use a pair of rails. Standard gauge (1.435 m / 56.5 in) is common but sled tracks of narrower or wider gauge also exist. The rail cross-section profile is usually that of a Vignoles rail, commonly used for railroads. Sliding pads, called "slippers", are curved around the head of the rails to prevent the sled from flying off the track. Air cushions and magnetic levitation have also been used as alternatives, with potential benefits including reduced sled vibration. A rocket sled holds the land-based speed ...

Holloman AFB
Holloman Air Force Base is a United States Air Force base established in 1942 located six miles (10 km) southwest of the central business district of Alamogordo, which is the county seat of Otero County, New Mexico, United States. The base was named in honor of Col. George V. Holloman, a pioneer in guided missile research. It is the home of the 49th Wing (49 WG) of the Air Education and Training Command (AETC). In addition to hosting several combat wings, Holloman supports the nearby White Sands Missile Range and currently hosts the Royal Air Force RPAS (Remotely Piloted Aircraft System) Formal Training Unit (FTU) and the Italian Air Force RPA training courses. The base previously hosted the German Air Force Flying Training Center. History Planned for the British Overseas Training program which was not pursued, construction for the USAAF base west of Alamogordo, New Mexico, began on 6 February 1942. After the nearby Alamogordo Bombing and Gunnery Range was establis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Stapp
John Paul Stapp (July 11, 1910 – November 13, 1999) was an American career U.S. Air Force officer, flight surgeon, physician, biophysicist, and pioneer in studying the effects of acceleration forces on humans. He was a colleague and contemporary of Chuck Yeager, and became known as "the fastest man on earth". His work on Project Manhigh pioneered many developments for the US space program. Early years Born in Salvador de Bahia, Brazil, Stapp was the eldest of four sons of Reverend Charles Franklin Stapp and Mrs. Mary Louise Shannon, Baptist missionaries. He studied in Texas at Brownwood High School in Brownwood and San Marcos Baptist Academy in San Marcos. In 1931, Stapp received a bachelor's degree from Baylor University in Waco, an MA from Baylor in 1932, a PhD in Biophysics from the University of Texas at Austin in 1940, and an MD from the University of Minnesota, Twin Cities, in 1944. He interned for one year at St. Mary's Hospital in Duluth, Minnesota. Stapp w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G-force
The g-force or gravitational force equivalent is a Specific force, mass-specific force (force per unit mass), expressed in Unit of measurement, units of standard gravity (symbol ''g'' or ''g''0, not to be confused with "g", the symbol for grams). It is used for sustained accelerations that cause a perception of weight. For example, an object at rest on Earth's surface is subject to 1 ''g'', equaling the conventional value of gravitational acceleration on Earth, about . More transient acceleration, accompanied with significant jerk (physics), jerk, is called Shock (mechanics), ''shock''. When the g-force is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite force for every unit of each object's mass. The types of forces involved are transmitted through objects by interior Stress (mechanics), mechanical stresses. Gravitational acceleration is one cause of an object's accelera ...

Water Brake
A water brake is a type of fluid coupling used to absorb mechanical energy and usually consists of a turbine or propeller mounted in an enclosure filled with water. As the turbine or propeller turns, mechanical energy is transferred to the water due to turbulence and friction. The shock caused by the acceleration of the water as it passes from pockets in the stator to the pockets in the spinning rotor requires energy. That energy heats the water due to the friction as the water moves through the water brake. Almost all of the horsepower of the system turning the rotor (usually an internal combustion engine) is converted into a temperature change of the water. A very small amount of energy is taken by the bearings and seals within the unit. Therefore, water must constantly move through the device at a rate proportional to the horse power that is being absorbed. Water temperature exiting the unit must be kept under to prevent scale formation and cavitation. The water enters in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guinness Book Of World Records
''Guinness World Records'', known from its inception in 1955 until 1999 as ''The Guinness Book of Records'' and in previous United States editions as ''The Guinness Book of World Records'', is a British reference book published annually, listing world records both of human achievements and the extremes of the natural world. Sir Hugh Beaver created the concept, and twin brothers Norris and Ross McWhirter co-founded the book in London in August 1955. The first edition topped the bestseller list in the United Kingdom by Christmas 1955. The following year the book was launched internationally, and as of the 2025 edition, it is now in its 70th year of publication, published in 100 countries and 40 languages, and maintains over 53,000 records in its database. The international franchise has extended beyond print to include television series and museums. The popularity of the franchise has resulted in ''Guinness World Records'' becoming the primary international source for catal ...
