Jerzy Dąbrowski (Lieutenant Colonel)
Jerzy Dąbrowski (September 8, 1899 – September 17, 1967) was a Polish aeronautical engineer. He was the lead designer of the famed PZL.37 Łoś medium bomber. Dąbrowski was born in Nieborów, west of Warsaw to a railway clerk family. He studied architecture and then transferred to mechanical engineering at the Warsaw Technical University (Polytechnic). The department offered aviation speciality and had an aviation fan club. Dąbrowski designed and built his first aircraft, biplane ultralight Dabrowski D.1 Cykacz, D.1 Cykacz (Ticker) in 1924 at the Centralne Warsztaty Lotnicze (Central Aviation Workshops) in Warsaw. In 1925 Dąbrowski obtained a special permission to complete pilot training at the 1st Air Regiment. Due to financial difficulties Jerzy left the Polytechnic in 1926 and started working at the Plage & Laskiewicz company contributing to the design of the Lublin R.VIII, R.IX. and DUS-III. In 1928 he was asked to join the PZL aviation works in Warsaw. There, with Dr. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeronautical Engineer
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, Air propulsion, avionics, materials science, stru ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Renton, Washington
Renton is a city in King County, Washington, and an inner-ring suburb of Seattle. Situated southeast of downtown Seattle, Renton straddles the southeast shore of Lake Washington, at the mouth of the Cedar River. As of the 2020 census, the population of Renton was 106,785, up from 90,927 at the 2010 census. The city is currently the sixth-largest municipality in greater Seattle and the ninth-largest in Washington state. After a long history as an important salmon fishing area for Native Americans, Renton was first settled by people of European descent in the 1860s. Its early economy was based on coal mining, clay production, and timber export. Today, Renton is best known as the final assembly point for the Boeing 737 family of commercial airplanes, but it is also home to a growing number of well-known manufacturing, technology, and healthcare organizations, including Boeing Commercial Airplanes Division, Paccar, Kaiser Permanente, IKEA, Providence Health & Services, UW Me ...

Cessna
Cessna () is an American brand of general aviation aircraft owned by Textron Aviation since 2014, headquartered in Wichita, Kansas. Originally, it was a brand of the Cessna Aircraft Company, an American general aviation aircraft manufacturing corporation also headquartered in Wichita. The company produced small, piston-powered aircraft, as well as business jets. For much of the mid-to-late 20th century, Cessna was one of the highest-volume and most diverse producers of general aviation aircraft in the world. It was founded in 1927 by Clyde Cessna and Victor Roos and was purchased by General Dynamics in 1985, then by Textron, Inc. in 1992.

Folland Aircraft
Folland Aircraft was a British aircraft manufacturing company which was active between 1937 and 1963. History British Marine Aircraft Limited was formed in February 1936 to produce Sikorsky S-42-A flying boats under licence in the UK. The company built a factory on the western side of the Hamble peninsula with a slipway to Southampton Water. The construction of one Sikorsky based aircraft was started at Hamble, however the company ran out of money and liquidators were appointed. Mergers with other British aircraft companies were considered, including one with Westland Aircraft, but none was followed up.Fagan, Dave.

Percival Aircraft
Hunting Aircraft was a British aircraft manufacturer that produced light training aircraft and the initial design that would evolve into the BAC 1-11 jet airliner. Founded as Percival Aircraft Co. in 1933, the company later moved to Luton, UK. It was eventually taken over by the British Aircraft Corporation (BAC) in 1960. History The company was formed as Percival Aircraft Co. in Gravesend in 1933 by Edgar Percival to produce his own designs. Restructured in 1936, it became Percival Aircraft Ltd, and moved to Luton Airport. The company became part of the Hunting Group in 1944. Percival, who had resigned from the board to serve in the Royal Air Force Volunteer Reserve during the war sold his remaining interest in the company at that point. From 1947 some internal components of Britain's Blue Danube atomic bomb were designed and manufactured by Percival Aircraft, in collaboration with the High Explosive Research project at Fort Halstead, Kent.

Invasion Of Poland (1939)
The invasion of Poland (1 September – 6 October 1939) was a joint attack on the Republic of Poland by Nazi Germany and the Soviet Union which marked the beginning of World War II. The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact between Germany and the Soviet Union, and one day after the Supreme Soviet of the Soviet Union had approved the pact. The Soviets invaded Poland on 17 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German–Soviet Frontier Treaty. The invasion is also known in Poland as the September campaign ( pl, kampania wrześniowa) or 1939 defensive war ( pl, wojna obronna 1939 roku, links=no) and known in Germany as the Poland campaign (german: Überfall auf Polen, Polenfeldzug). German forces invaded Poland from the north, south, and west the morning after the Gleiwitz incident. Slovak military forces adv ...

Laminar Flow
In fluid dynamics, laminar flow is characterized by fluid particles following smooth paths in layers, with each layer moving smoothly past the adjacent layers with little or no mixing. At low velocities, the fluid tends to flow without lateral mixing, and adjacent layers slide past one another like playing cards. There are no cross-currents perpendicular to the direction of flow, nor eddies or swirls of fluids. In laminar flow, the motion of the particles of the fluid is very orderly with particles close to a solid surface moving in straight lines parallel to that surface. Laminar flow is a flow regime characterized by high momentum diffusion and low momentum convection. When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow. Laminar flow occurs at lower velocities, below a threshold at which the flow becomes turbulent. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
