Frank Piasecki ( // pee-ə-SEK-ee; Polish: [pjaˈsɛtski] ; October 24, 1919 – February 11, 2008) was an American engineer and helicopter aviation pioneer. Piasecki pioneered tandem rotor helicopter designs and created the compound helicopter concept of vectored thrust using a ducted propeller.
A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL aircraft cannot perform.
Born in Philadelphia, Pennsylvania to an immigrant Polish tailor, Piasecki worked for autogyro manufacturers while still attending Overbrook High School,then studied mechanical engineering at the University of Pennsylvania before graduating with a bachelor's degree from New York University. In 1940, he formed PV Engineering Forum with former Pennsylvania classmate Harold Venzie. He built a single-person, single-rotor helicopter designated the PV-2 and flew it on April 11, 1943. This helicopter impressed the United States Navy sufficiently to win Piasecki a development contract.
Philadelphia, known colloquially as Philly, is the largest city in the U.S. state and Commonwealth of Pennsylvania, and the sixth-most populous U.S. city, with a 2018 census-estimated population of 1,584,138. Since 1854, the city has been coterminous with Philadelphia County, the most populous county in Pennsylvania and the urban core of the eighth-largest U.S. metropolitan statistical area, with over 6 million residents as of 2017. Philadelphia is also the economic and cultural anchor of the greater Delaware Valley, located along the lower Delaware and Schuylkill Rivers, within the Northeast megalopolis. The Delaware Valley's population of 7.2 million ranks it as the eighth-largest combined statistical area in the United States.
Pennsylvania, officially the Commonwealth of Pennsylvania, is a state located in the northeastern, Great Lakes and Mid-Atlantic regions of the United States. The Appalachian Mountains run through its middle. The Commonwealth is bordered by Delaware to the southeast, Maryland to the south, West Virginia to the southwest, Ohio to the west, Lake Erie and the Canadian province of Ontario to the northwest, New York to the north, and New Jersey to the east.
Poland, officially the Republic of Poland, is a country located in Central Europe. It is divided into 16 administrative subdivisions, covering an area of 312,696 square kilometres (120,733 sq mi), and has a largely temperate seasonal climate. With a population of approximately 38.5 million people, Poland is the sixth most populous member state of the European Union. Poland's capital and largest metropolis is Warsaw. Other major cities include Kraków, Łódź, Wrocław, Poznań, Gdańsk, and Szczecin.
The name PV Engineering was changed to Piasecki Helicopter Corporation in 1946. After a boardroom dispute, Piasecki left Piasecki Helicopter in 1955 and formed the Piasecki Aircraft Company.
Piasecki Helicopter Corporation was a designer and manufacturer of helicopters located in Philadelphia and nearby Morton, Pennsylvania, in the late 1940s and the 1950s. Its founder, Frank Piasecki, was ousted from the company in 1956 and started a new company, Piasecki Aircraft. Piasecki Helicopter was renamed Vertol Corporation in early 1956. Vertol was acquired by Boeing in 1960 and renamed Boeing Vertol.
The Piasecki Aircraft Corporation (PiAC) was founded by American vertical flight pioneer Frank Piasecki to develop compound helicopters and other advanced rotorcraft after he was ousted from the leadership of his first company, Piasecki Helicopter.
At Piasecki Aircraft, he participated in the development of the Piasecki 16H-1 the world's first shaft driven compound helicopter, the PA-59K/VZ-8P Flying Geep, the Piasecki PA-97 Helistat heavy vertical airlifter and the Piasecki X-49 experimental compound helicopter.
The Piasecki X-49 "SpeedHawk" is an American four-bladed, twin-engined experimental high-speed compound helicopter developed by Piasecki Aircraft. The X-49A is based on the airframe of a Sikorsky YSH-60F Seahawk, but utilizes Piasecki's proprietary vectored thrust ducted propeller (VTDP) design and includes the addition of lifting wings. The concept of the experimental program was to apply the VTDP technology to a production military helicopter to determine any benefit gained through increases in performance or useful load.
Piasecki married Vivian O'Gara Weyerhaeuser on December 20, 1958.They had seven children: Nicole, Frederick, John, Lynn, Frank, Michael, and Gregory.
His son John W. Piasecki is now President and CEO of Piasecki Aircraft. His son Fred W. Piasecki is Chairman of the Board and Chief Technology Officer of Piasecki Aircraft.His daughter Nicole Piasecki is vice president and general manager of Propulsion Systems for Boeing Commercial Airplanes.
Boeing Commercial Airplanes (BCA) is a division of the Boeing Company. It designs, assembles, markets, and sells jet airliners and business jets ; it also provides product-related maintenance and training to customers worldwide. It operates from division headquarters in Renton, Washington, with more than a dozen engineering, manufacturing, and assembly facilities located throughout the U.S. and internationally. BCA includes the assets of the Douglas Aircraft division of the former McDonnell Douglas Corporation, which merged with Boeing in 1997. In late 2016, BCA was home to some 78,000 employees.
Piasecki died at his home on February 11, 2008 after a series of strokes. He was 88.
The Steven F. Udvar-Hazy Center, also called the Udvar-Hazy Center, is the Smithsonian National Air and Space Museum (NASM)'s annex at Washington Dulles International Airport in the Chantilly area of Fairfax County, Virginia, United States. It holds numerous exhibits, including the Space Shuttle Discovery and the Enola Gay.
New York Airways was a helicopter airline in the New York City area, founded in 1949 as a mail and cargo carrier. On 9 July 1953 it may have been the first scheduled helicopter airline to carry passengers in the United States, with headquarters at LaGuardia Airport. Although primarily a helicopter airline operator with scheduled passenger operations, New York Airways also flew fixed wing aircraft, such as the de Havilland Canada DHC-6 Twin Otter 19-passenger STOL twin turboprop aircraft.
The Piasecki HUP Retriever/H-25 Army Mule was a compact single radial engine, twin overlapping tandem rotor utility helicopter developed by the Piasecki Helicopter Corporation of Morton, Pennsylvania. Designed to a United States Navy specification, the helicopter was produced from 1949 to 1954, and was also used by the United States Army and foreign navies. The HUP/H-25 was the first helicopter to perform a loop and to be produced with an autopilot.
The Sikorsky X2 is an experimental high-speed compound helicopter with coaxial rotors developed by Sikorsky Aircraft.
Powered lift or powered-lift refers to a type of aircraft that can take off and land vertically and functions differently from a rotorcraft in horizontal flight.
The Piasecki VZ-8 Airgeep was a prototype vertical takeoff and landing (VTOL) aircraft developed by Piasecki Aircraft. The Airgeep was developed to fulfill a U.S. Army Transportation Research Command contract for a flying jeep in 1957. The flying jeep was envisioned to be smaller and easier to fly than a helicopter.
D. K. or "Gish" Jovanovich was a Serbian-American helicopter designer, inventor, and pioneer in autogyro technology.
The Piasecki PV-2 was a helicopter designed by Frank Piasecki. The PV-2 is best known for being the second successful helicopter flown in the United States. The PV-2 first flew on April 11, 1943. Developed as a technology demonstrator, the PV-2 brought several new features such as the first dynamically balanced rotor blades, a rigid tail rotor with a tension-torsion pitch change system, and a full cyclic and collective rotor pitch control.

The transport museum focuses on the history, science and technology of rotary wing aviation. The collection contains over 40 civilian and military autogyros, convertiplanes and helicopters, including some early generation models. The museum also has an extensive research library, the Renzo Pierpaoli Memorial Library, which contains documents, artifacts, films, and memoirs that museum members can use.
The Piasecki HRP Rescuer was a United States tandem-rotor transport or rescue helicopter designed by Frank Piasecki and built by Piasecki Helicopter. The Piasecki PV-3 was adopted as the HRP-1 Rescuer by the United States Navy, United States Marine Corps, and United States Coast Guard. An improved PV-17 variant was later produced as the HRP-2. As one of the first transport helicopters in military service, the HRP-1 was capable of carrying two crewmen and 8-10 passengers or 2,000 lb. (907 kg) of cargo.
The Piasecki PA-97 Helistat was an American experimental heavy-lift aircraft, built by Piasecki by fastening four H-34J helicopters to a framework beneath a helium-inflated blimp envelope. It crashed during a test flight, killing one of the four pilots.
The SkyHook JHL-40 was a proposed hybrid airship/helicopter. On July 9, 2008, Boeing announced that it had teamed up with SkyHook International, a Canadian company, to develop this aircraft. No further press releases appear after 2009 and Skyhook International has abandoned its domain name registration since 2010 as shown by the Internet Archive.
The Piasecki H-16 Transporter was a tandem-rotor transport or rescue helicopter designed by Frank Piasecki and built by Piasecki Helicopter. The prototypes were evaluated by the United States Air Force and Army, but the crash of the second test aircraft led to cancelling the project.
Frank Kozloski (1916–2003) was an aeronautical engineer who worked on early tandem rotor helicopters and was one of the founders of Piasecki Helicopter's.
Donovan Reese Berlin was an American military aircraft designer and aircraft industry executive. Among the many designs with which he is associated, are the Curtiss P-36 Hawk, Curtiss P-40 Warhawk and Fisher P-75 Eagle. His name is "synonymous with the development of military aviation". He designed aircraft that were safe, rugged and "a pilot's joy."
