The XCOR EZ-Rocket was a test platform for the XCOR XR-4A3 rocket propulsion system. The airplane was a modified Rutan Long-EZ , with the propeller replaced by first one, then later a pair of pressure-fed regeneratively cooled liquid-fueled rocket engines and an underslung fuel tank. The engines were restartable in flight, and were contained within Kevlar armor shielding. The EZ-Rocket was registered as an experimental aircraft .

33-522: The first flight took place on July 21, 2001, flown by test pilot Dick Rutan . On a typical flight, the EZ-Rocket took off on rockets, gained altitude for a minute or so, then switched off the rockets and glided to a dead stick landing . The vehicle actually flew better during dead stick landings than a standard Long-EZ due to lack of drag from a stationary pusher propeller — the vehicle's aerodynamics were cleaner in spite of its belly tank. It

66-467: A co-founder of XCOR, said on February 10, 2003 if they were starting out at that time they probably would seek an AST license due to the progress made in developing a regulatory regime for suborbitals. The Rocket Racing League aircraft currently in development, the Mark-III X-racer , is a design descendant of the EZ-Rocket aircraft. Although XCOR is not the developer of the rocket engine for

99-642: A few clusters of vacation homes. The Cedar Point community included several churches, a post office, and a gas station. Some of the old homes now serve as quarters for Navy personnel stationed there. In 1937, the Navy's Bureau of Aeronautics sought to consolidate aviation test programs, previously being conducted at several stations, including Dahlgren and Norfolk , the Washington Navy Yard , Naval Air Station Anacostia in Washington, D.C. , and

132-545: A living reminder of that debt." Since the end of the Cold War , the Pentagon 's Base Realignment and Closure measures have migrated research and testing facilities for both rotary and fixed-wing aircraft to NAS Patuxent River from decommissioned bases. The complex now hosts over 17,000 people, including active-duty service members, civil-service employees, defense contractor employees, and military dependents . The base

165-532: A small outlying field , NOLF Webster . Commissioned on April 1, 1943, on land largely acquired through eminent domain , the air station grew rapidly in response to World War II and continued to evolve through the Cold War to the present. The 6,400 acres (26 km ) Naval Air Station Patuxent River site is located in Lexington Park, Maryland , at the confluence of the Patuxent River and

198-919: A systematic activity started during the First World War , at the Royal Aircraft Establishment (RAE) in the United Kingdom . An "Experimental Flight" was formed at the Central Flying School . During the 1920s, test flying was further developed by the RAE in the UK, and by the National Advisory Committee for Aeronautics (NACA) in the United States . In the 1950s, NACA was transformed into

231-459: A year of construction. Employing some 7,000 at its peak of construction, the area had a Gold Rush "boom town" feel as local residents were joined by workers from all over the country, eager to get on the high-paying jobs on station. On 20 October 1942, U.S. Marines first arrived and took over security. Today, the station utilizes Navy Masters-At-Arms (MA) and Navy Civilian Police Department of Defense Police for standard local law enforcement and

264-621: Is a United States naval air station located in St. Mary’s County , Maryland , on the Chesapeake Bay near the mouth of the Patuxent River . It is home to Headquarters, Naval Air Systems Command (NAVAIR), the U.S. Naval Test Pilot School , the Atlantic Test Range , Patuxent River Naval Air Museum , and serves as a center for test and evaluation and systems acquisition relating to naval aviation . The station also operates

297-769: Is now called the Empire Test Pilots' School (motto "Learn to Test – Test to Learn"), at RAF Boscombe Down in the UK. There are a number of similar establishments over the world . In America, the United States Air Force Test Pilot School is located at Edwards Air Force Base , the United States Naval Test Pilot School is located at Naval Air Station Patuxent River , Maryland and EPNER ( Ecole du Personnel Navigant d'Essai et de Reception – "School for flight test and acceptance personnel"),

330-561: The Battle of the Coral Sea on 8 May 1942. The town's expansion had begun. The station was commissioned "U.S. Naval Air Station, Patuxent River, Maryland" on 1 April 1943. In a ceremony presided over by RADM John S. McCain, Sr. , then chief of the Bureau of Aeronautics , Patuxent River was referred to as "the most needed station in the Navy." The unofficial name had been Cedar Point or

363-398: The Chesapeake Bay on a peninsula known as Cedar Point. Naval Air Station Patuxent River (PAX) operated several landfills and other historical disposal areas. The landfills received solid and hazardous wastes . This included spent oil absorbents, solvents, paints, antifreeze, thinners, pesticides and photo lab wastes, sewage treatment plant sludge, cesspool wastes. In the late 1950s, DDT

396-563: The National Aeronautics and Space Administration , or NASA. During these years, as work was done into aircraft stability and handling qualities, test flying evolved towards a more qualitative scientific profession. In the 1950s, test pilots were being killed at the rate of about one a week, but the risks have shrunk to a fraction of that because of the maturation of aircraft technology, better ground-testing and simulation of aircraft performance, fly-by-wire technology and, lately,

429-637: The Naval Air Station at Cedar Point , but officials were concerned about possible confusion with the Marine Corps Air Station Cherry Point , North Carolina , so the new facility was named for the adjacent river. In 1945 the Test Pilot School was established with the Navy's Flight Test Group transferred from Naval Air Station Anacostia , Washington, DC to NAS Patuxent River. On June 16, 1945,

462-668: The Naval Aircraft Factory in Philadelphia , Pennsylvania . Cedar Point was selected due to its remote location on the coastline, well removed from air traffic congestion, with ample space for weapons testing. The onset of American involvement in World War II spurred establishment of the new air station. Rear Admiral John Henry Towers , Chief of Bureau of Aeronautics, requested approval and authorization to begin construction on December 22, 1941. Secretary of

495-578: The Naval Criminal Investigative Service (NCIS) for high-profile criminal investigations. During construction, housing needs far outstripped supply, and barracks were built for workers on the station. Later, several housing areas were erected off station for workers and their families in Lexington Park , formerly Jarboesville , named in honor of the USS Lexington , the Navy's second aircraft carrier, lost during

528-626: The 1970s. The Grumman F-14 Tomcat , the McDonnell Douglas AV-8B Harrier II jump jet, and the Lockheed P-3 Orion were just a few of the major aircraft programs undergoing the rigorous test and evaluation process at NAS Patuxent River. Helicopter programs also achieved major milestones during the 1970s. The Naval Air Test Center (NATC) at NAS Patuxent River took part in helicopter development and testing for new roles, such as minesweeping. The final flight of

561-627: The Air Combat Environment Test and Evaluation Facility, the Aircraft Test and Evaluation Facility, and the Captain Steven A. Hazelrigg Flight Test Facility. The physical plant was expanded by new construction: the U.S. Naval Test Pilot School academic building, an Aviation Survival Training Center pool facility and a new air-traffic-control tower . The base's social infrastructure has grown as well. In 2013,

594-1028: The French test pilot school, is located in Istres , France. There are only two civilian schools; the International Test Pilots School in London, Ontario , and the National Test Pilot School , a not-for-profit educational institute is in Mojave, California. In Russia , there is a Russian aviation industry Fedotov Test Pilot School (founded 1947) located in Zhukovsky within the Gromov Flight Research Institute . Test pilots can be experimental and engineering test pilots (investigating

627-817: The Mark-III, XCOR did develop the rocket engine for the Mark-I X-Racer , the first of the X-Racers to use a single rocket engine on a Velocity SE basic airframe, and the first X-Racer to utilize kerosene instead of isopropyl alcohol fuel. XCOR used both design and operational experience from the EZ-Rocket in the Mark-I rocket aircraft design. Test pilot A test pilot is an aircraft pilot with additional training to fly and evaluate experimental, newly produced and modified aircraft with specific maneuvers, known as flight test techniques. Test flying as

660-611: The National Command Center and the ballistic missile submarine fleet. Two LTV A-7 Corsair II aircraft made the transatlantic crossing from NAS Patuxent River to Évreux, France, in 1967, racking up 3,327 nautical miles in just over seven hours, an unofficial long-distance, non-refueled flight by light attack jet aircraft. Cooperation with the British led to transatlantic visits to Pax River by RAF squadrons. Research and development at NAS Patuxent River forged ahead in

693-759: The Naval Air Test Center was established as a separate entity, incorporating flight test and other test groups, at the Naval Air Station. The base became a center for testing as several facilities were constructed throughout the 1950s and 1960s, including the facilities for United States Naval Test Pilot School (1958), the Weapons Systems Test Division (1960), and the Propulsion System Evaluation Facility. The base also served as

726-474: The Navy, Frank Knox , gave approval on 7 January 1942. Construction began on 4 April 1942. The original civilian residents had about a month, until 1 March 1942, to relocate, as the federal government purchased all the land at a cost of $ 712,287 for 6,412 acres (26 km ), which in 2013 dollars would be the equivalent of being paid $ 1,261 per acre. Many residents were forced to sell land that had been in their families for generations. Some families had roots in

759-553: The air station. Known as the U.S. Government Railroad, the rail line was steam-powered and operated south of Brandywine for exclusive official use until 1954, when the Pennsylvania Railroad assumed operation of the line. Rail service ended in 1965, and the line was scrapped, although the right-of-way is still very visible. A highway extension to the new air station was required by the project—250,000 tons of material were transported by either truck or water routes during

792-730: The area going back 300 years. These included traditional farming, crabbing and fishing families and there were protests. National wartime urgency was felt in Washington at the time to take precedence, and the process of eminent domain went through. A lack of transportation in Saint Mary's County led the Navy to acquire and revitalize a branchline called the Washington, Brandywine and Point Lookout Railroad , aka "The Farmers' Railroad", from Brandywine to Mechanicsville , Maryland , in June 1942 and build an extension south from Mechanicsville to

825-703: The characteristics of new types of aircraft during development) or production test pilots (the more mundane role of confirming the characteristics of new aircraft as they come off the production line). Many test pilots would perform both roles during their careers. Modern test pilots often receive formal training from highly-selective military test pilot schools, but other test pilots receive training and experience from civilian institutions and/or manufacturers' test pilot development programs (see list of test pilot schools ). Naval Air Station Patuxent River Naval Air Station Patuxent River ( IATA : NHK , ICAO : KNHK , FAA LID : NHK ), also known as NAS Pax River ,

858-514: The remaining areas, investigations and remedy selection activities continue. For example, in April 2021 the Navy disclosed at a NAS Patuxent River Restoration Advisory Board meeting that 84,757 ppt of PFOS were detected in the groundwater at Webster Field. Prior to 1937 the area was prime farmland , consisting of several large plantations, Mattapony , Susquehanna , and Cedar Point, as well as numerous tenant and sharecropper properties and

891-528: The service acceptance trials for the Bell AH-1 SuperCobra gunship was made at NATC Patuxent River. On 1 April 1976, Patuxent River's airfield was named after pioneering aviator VADM Frederick M. Trapnell , a former commander of the Naval Air Test Center at the station. Keynote address speaker, ADM Frederick H. Michaelis , Chief of Naval Material , noted: "All who fly in Navy blue remain indebted to Vice Admiral Trapnell. This field will serve as

924-747: The testing facility for the V-22 Osprey . In addition to its role in testing naval aircraft, during the 1950s to 1970s Patuxent River served as an operational base for a Transport Squadron - VR-1, a TACAMO squadron - VQ-4, Airborne Training Unit Atlantic - AEWTULANT, and VW-11, VW-13 AN VW-15 and a number of Patrol Squadrons including VP-8 , VP-44, VP-49, VP-24, VP-30 and VP-68. By 1965, reconnaissance Squadron VQ-4, based at NAS Patuxent River, began using Lockheed C-130s equipped with special communications equipment to perform their around-the-clock Take Charge and Move Out (TACAMO) mission. VQ-4 provided long-range, very-low-frequency communications relay between

957-461: The use of unmanned aerial vehicles to test experimental aircraft features. Still, piloting experimental aircraft remains more dangerous than most other types of flying. At the insistence of President Dwight D. Eisenhower , the first American astronauts , the Mercury Seven , were all military test pilots, as were some of the later astronauts. The world's oldest test pilot school is what

990-573: Was a branch of the Naval Air Warfare Center, created in 1991, and located in Washington, DC. Its mission was the development and improvement of weapons. The partnership of these two units led to a "flourishing" of aircraft research and development at Patuxent. A number of new laboratory facilities on the forefront of research were created: a manned flight simulator, the Aircraft Anechoic Test Facility,

1023-501: Was also lighter due to the lack of a piston engine (the rocket propulsion system was significantly lighter), so enjoyed significantly lower wing loading than a standard Long-EZ. When XCOR began flying its EZ-Rocket in 2001, the company decided to have it FAA certified as an experimental aircraft , avoiding the additional time required to seek a launch vehicle license from the Office of Commercial Space Transportation (AST).

1056-661: Was sprayed and from 1962–1989 various pesticides, including fungicides and insecticides and herbicides, were used, contaminating the ground surface water and groundwater. Base residential housing was within a quarter mile. In May 1994, PAX was added to the Superfund program's National Priorities List . As of 2022, several areas were considered "cleaned up" after removing contaminated soil, but there are ongoing maintenance activities such as monitoring and treatment of landfill gas , groundwater, and using land use controls and institutional controls, eg. restricting fish consumption. At

1089-679: Was used as a filming location for the Harrison Ford film Random Hearts (1999). Ford and director Sydney Pollack both visited Naval Air Station Patuxent River. Ford, a certified pilot, flew the aircraft himself. In January 1992, the Pax River Station acquired the Aircraft Division of the Naval Air Warfare Center (NAWCAD). The Naval Test Wing Atlantic (NTWL) was already located there, which
