The Messerschmitt Me 163 Komet is a rocket-powered interceptor aircraft primarily designed and produced by the German aircraft manufacturer Messerschmitt. It is the only operational rocket-powered fighter aircraft in history as well as the first piloted aircraft of any type to exceed 1,000 kilometres per hour (620 mph) in level flight.
Opel Automobile GmbH, usually shortened to Opel, is a German automobile manufacturer which has been a subsidiary of Stellantis since 16 January 2021. It was owned by the American automaker General Motors from 1929 until 2017 and the PSA Group prior to its merger with Fiat Chrysler Automobiles to form Stellantis in 2021. Most of the Opel lineup is marketed under the Vauxhall brand in the United Kingdom since the 1980s. Some Opel vehicles were badge-engineered in Australia under the Holden brand until 2020, in North America and China under the Buick, Saturn, and Cadillac brands, and in South America under the Chevrolet brand.
JATO is a type of assisted take-off for helping overloaded aircraft into the air by providing additional thrust in the form of small rockets. The term JATO is used interchangeably with the term RATO, for rocket-assisted take-off.
A jet aircraft is an aircraft propelled by one or more jet engines.
Alexander Martin Lippisch was a German aeronautical engineer, a pioneer of aerodynamics who made important contributions to the understanding of tailless aircraft, delta wings and the ground effect, and also worked in the U.S. Within the Opel-RAK program, he was the designer of the world's first rocket-powered glider.
The Heinkel He 176 was a German experimental rocket-powered aircraft. It was the world's first aircraft to be propelled solely by a liquid-fueled rocket, making its first powered flight on 20 June 1939 with Erich Warsitz at the controls.
The Opel RAK.1 was the world's first purpose-built rocket-powered aircraft. It was designed and built by Julius Hatry under commission from Fritz von Opel, who flew it on September 30, 1929 in front of a large crowd at Rebstock airport near Frankfurt am Main. The RAK.1 plane was part of a series of rocket-powered vehicles that were developed and demonstrated within the Opel RAK program, the world's first large-scale rocket program.
Fritz Adam Hermann von Opel, known as Fritz Adam Hermann Opel until his father was ennobled in 1917, was the only son of Wilhelm von Opel and a grandson of Adam Opel, founder of the Opel company. He is remembered mostly for his Opel RAK demonstrations of the world's first manned rocket-powered ground and air vehicles that earned him the nickname "Rocket Fritz" and which were also highly effective as publicity stunts for his family's automotive business.
Julius Hatry was a German aircraft designer and builder. He is remembered for his contributions to sailplane development in the early twentieth century and for building the world's first purpose-built rocket plane, the Opel RAK.1.
Friedrich Wilhelm Sander was a German pyrotechnics and rocket technology engineer as well as manufacturer remembered for his contributions to rocket-powered flight as key protagonist of the Opel-RAK program.
Max Valier was an Austrian rocketry pioneer. He was a leading figure in the world's first large-scale rocket program, Opel-RAK, and helped found the German Verein für Raumschiffahrt that would bring together many of the minds that would later make spaceflight a reality in the 20th century.
Johannes Winkler was a German rocket pioneer who co-founded with Max Valier of Opel RAK the first German rocket society "Verein für Raumschiffahrt" and launched, after Friedrich Wilhelm Sander's successful Opel RAK liquid-rocket launches in 1929, one of the first successful liquid-fuelled rocket in Europe.
A liquid-propellant rocket or liquid rocket utilizes a rocket engine burning liquid propellants. (Alternate approaches use gaseous or solid propellants.) Liquids are desirable propellants because they have reasonably high density and their combustion products have high specific impulse (Isp). This allows the volume of the propellant tanks to be relatively low.
A rocket-powered aircraft or rocket plane is an aircraft that uses a rocket engine for propulsion, sometimes in addition to airbreathing jet engines. Rocket planes can achieve much higher speeds than similarly sized jet aircraft, but typically for at most a few minutes of powered operation, followed by a gliding flight. Unhindered by the need for oxygen from the atmosphere, they are suitable for very high-altitude flight. They are also capable of delivering much higher acceleration and shorter takeoffs. Many rocket aircraft may be drop launched from transport planes, as take-off from ground may leave them with insufficient time to reach high altitudes.
The Convair XF-92 was an American, delta wing, first-generation jet prototype. Originally conceived as a point-defence interceptor, the design was later used purely for experimental purposes and only one was built. However, it led Convair to use the delta-wing on a number of designs, including the F-102 Delta Dagger, F-106 Delta Dart, B-58 Hustler, the US Navy's F2Y Sea Dart as well as the VTOL FY Pogo.
A rocket car is a land vehicle propelled by a rocket engine. A rocket dragster is a rocket car used for competing in drag racing, and this type holds the unofficial world record for the 1/4 mile.
The Technoseum is a technology museum in Mannheim, Baden-Württemberg, Germany, with displays covering the industrialisation of the south-western regions of the country.
Opel-RAK were a series of rocket vehicles produced by German automobile manufacturer Fritz von Opel, of the Opel car company, in association with others, including Max Valier, Julius Hatry, and Friedrich Wilhelm Sander. Opel RAK is generally considered the world's first large-scale rocket program, significantly advancing rocket and aviation technology as well as instrumental in popularizing rockets as means of propulsion. In addition Opel RAK demonstrations were also highly successful as publicity stunts for the Opel car company. The Lippisch Ente, the world's first rocket-powered glider and piloted for its first flight on June 11, 1928, by Fritz Stamer at Wasserkuppe, was bought and operated by Opel in context of the Opel RAK program but is not formally designated an Opel RAK series number. Also a rocket-powered RAK-Motoclub motorbike, based on a conventional Opel Motoclub 500 SS and presented at the Berlin Motorshow 1928, did not receive a formal RAK number.
Weltensegler G.m.b.H. was a German aircraft company formed by Friedrich Wenk, who became its Technical Director.
The 1926 German RRG Prüfling of 1926 was a secondary training glider designed for club use. Plans were sold and it was built in Germany and across the world.
