Paul H. Knepper was an American aircraft engineer.
Knepper was born in Tamaqua, Pennsylvania.
He worked at several aircraft companies before becoming an instructor at the Pittsburgh Institute of Aeronautics, where he designed his first airplane, [1] the Ka-1 Crusader as a prototype for a training plane that he wanted to commercially produce in Lehighton, Pennsylvania. The two-seater featured an innovative tricycle landing gear with a wheel under its nose, instead of the tail, from dragging upon landing. [2]
Although advanced for its day the Crusader was never commercially produced, since World War II forced a halt in the manufacture of commercial aircraft.
In 1990, friends of Paul Knepper restored the Crusader, and it was donated by his widow, Ruth I. Knepper to the State Museum of Pennsylvania in Harrisburg. [3] [4]
A fixed-wing aircraft is a heavier-than-air aircraft, such as an airplane, which is capable of flight using aerodynamic lift. Fixed-wing aircraft are distinct from rotary-wing aircraft, and ornithopters. The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft, and airplanes that use wing morphing are all classified as fixed wing.
The Boeing 727 is an American narrow-body airliner that was developed and produced by Boeing Commercial Airplanes. After the heavier 707 quad-jet was introduced in 1958, Boeing addressed the demand for shorter flight lengths from smaller airports. On December 5, 1960, the 727 was launched with 40 orders each from United Airlines and Eastern Air Lines. The first 727-100 rolled out on November 27, 1962, first flew on February 9, 1963, and entered service with Eastern on February 1, 1964.
Tamaqua is a borough in eastern Schuylkill County in the Coal Region of Pennsylvania, United States. It had a population of 6,934 as of the 2020 U.S. census.
Air Force One is the official air traffic control designated call sign for a United States Air Force aircraft carrying the president of the United States. The term is commonly used to denote U.S. Air Force aircraft modified and used to transport the president, and as a metonym for the primary presidential aircraft, VC-25, although it can be used to refer to any Air Force aircraft the president travels on.
Glenn Hammond Curtiss was an American aviation and motorcycling pioneer, and a founder of the U.S. aircraft industry. He began his career as a bicycle racer and builder before moving on to motorcycles. As early as 1904, he began to manufacture engines for airships. In 1908, Curtiss joined the Aerial Experiment Association, a pioneering research group, founded by Alexander Graham Bell at Beinn Bhreagh, Nova Scotia, to build flying machines.
The ERCO Ercoupe is an American low-wing monoplane aircraft that was first flown in 1937. It was originally manufactured by the Engineering and Research Corporation (ERCO) shortly before World War II; several other manufacturers continued its production after the war. The final model, the Mooney M-10, first flew in 1968 and the last model year was 1970. It was designed to be the safest fixed-wing aircraft that aerospace engineering could provide at the time, and the type continues to enjoy a faithful following.
Elbert Leander "Burt" Rutan is a retired American aerospace engineer and entrepreneur noted for his originality in designing light, strong, unusual-looking, and energy-efficient air and space craft. He designed the record-breaking Voyager, which in 1986 was the first plane to fly around the world without stopping or refueling. He also designed the Virgin Atlantic GlobalFlyer, which in 2006 set the world record for the fastest and longest nonstop non-refueled circumnavigation flight in history. In 2004, Rutan's sub-orbital spaceplane design SpaceShipOne became the first privately funded spacecraft to enter the realm of space, winning the Ansari X-Prize that year for achieving the feat twice within a two-week period.
The Etrich Taube, also known by the names of the various later manufacturers who built versions of the type, such as the Rumpler Taube, was a pre-World War I monoplane aircraft. It was the first military aeroplane to be mass-produced in Germany.
The Wright Flyer made the first sustained flight by a manned heavier-than-air powered and controlled aircraft—an airplane—on December 17, 1903. Invented and flown by brothers Orville and Wilbur Wright, it marked the beginning of the pioneer era of aviation.
An airplane or aeroplane, informally plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometers of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled such as drones.
American Airlines Flight 157, a Douglas DC-6, departed on November 29, 1949, from New York City bound for Mexico City with 46 passengers and crew. After one engine failed in mid-flight, a series of critical mistakes by the flight crew caused the pilot to lose control of the plane during the final approach to a routine stopover at Love Field in Dallas, Texas. The airliner slid off the runway and struck a parked airplane, a hangar, and a flight school before crashing into a business across from the airport. 26 passengers and two flight attendants died. The pilot, co-pilot, flight engineer, and 15 passengers survived.
Sherman Mills Fairchild was an American businessman and investor who founded over 70 companies, including Fairchild Aviation, Fairchild Industries, and Fairchild Camera and Instrument. Fairchild made significant contributions to the aviation industry and was inducted into the National Aviation Hall of Fame in 1979. His Semiconductor Division of Fairchild Camera played a defining role in Silicon Valley. He held over 30 patents for products ranging from the silicon semiconductor to the 8-mm home sound motion-picture camera. Fairchild was responsible for inventing the first synchronized camera shutter and flash as well as developing technologies for aerial cameras that were later used on the Apollo Missions.
Giuseppe Mario Bellanca was an Italian-American aviation pioneer, airplane designer and builder, who is credited with many design firsts and whose aircraft broke many aviation records. He was inducted into the National Aviation Hall of Fame in 1973. The Bellanca C.F., one of the world's first enclosed-cabin monoplanes, is on display at the National Air and Space Museum. Bellanca was known mostly for his long range aircraft which led the way for the advancement of international and commercial air transportation.
The Dayton-Wright Company was formed in 1917, on the declaration of war between the United States and Germany, by a group of Ohio investors that included Charles F. Kettering and Edward A. Deeds of Dayton Engineering Laboratories Company (DELCO). Orville Wright lent his name and served as a consultant, but other than that, the location of one of its three factories in the original Wright Company factory buildings in Dayton, Ohio was the only connection to the Wright brothers. In addition to plant 3, Dayton-Wright operated factories in Moraine and Miamisburg, Ohio. During the course of the war, Dayton-Wright produced about 3,000 DH-4s, as well as 400 Standard SJ-1 trainers. The company was hurt by the reputation of the DH-4s it produced as "flaming coffins" or "flying coffins", although they were not in reality more subject to catching fire than other aircraft, and by scandals it faced.
The Fokker F-11 was a luxury flying boat produced as an 'air yacht' in the United States in the late 1920s. Technically the aircraft was the Fokker Aircraft Corporation of America's Model 9. It was sold in North America as the Fokker F-11 and was offered in Europe as the Fokker B.IV. By the time the first six aircraft had been constructed, it was already evident that the design was not going to sell well. A few were sold, two to notable multi-millionaires; Harold Vanderbilt and Garfield Wood each purchasing one. One was bought by Air Ferries in San Francisco. The F-11A cost $40,000 but the price was slashed to $32,500 as the depression set in during 1930. The F-11 was a commercial failure.
Alfred Victor Verville was an American aviation pioneer and aircraft designer who contributed to civilian and military aviation. During his forty-seven years in the aviation industry, he was responsible for the design and development of nearly twenty commercial and military airplanes. Verville is known for designing flying boats, military racing airplanes, and a series of commercial cabin airplanes. His planes were awarded with the Pulitzer Speed Classic Trophy in 1920 and 1924.
Ladislao Pazmany was an aviation pioneer, aeronautical engineer, designer, pilot, teacher, speaker, and author. Born in Hungary, Pazmany grew up, went to school, and worked in his formative years in Argentina. He then immigrated to the United States where he lived for the remainder of his life.
Knepper is a surname. Notable people with the surname include:
The Fahlin SF-2 Plymocoupe was a high-wing, cantilever type, prototype experimental airplane produced in 1935.
Albin Kasper Longren was an American aviation pioneer from the state of Kansas. Beginning in 1911, Longren successfully flew airplanes of his own design and construction. Fully self-taught as an aircraft designer and pilot, he built a thriving career as a barnstormer with his own craft, becoming known throughout the Midwest as the "Birdman".
