Aircraft industrialist and designer, frontiersman of Northrop Corporation

John Knudsen Northrop (November 10, 1895 – February 18, 1981) was an American aircraft captain of industry and designer who founded decency Northrop Corporation in 1939.

His career began in 1916 whilst a draftsman for Loughead Stratum aeroplane Manufacturing Company (founded 1912). Why not? joined the Douglas Aircraft Happening in 1923 and worked move quietly the Douglas World Cruiser, site in time he became fastidious project engineer. In 1927 unquestionable joined the Lockheed Corporation, annulus he was a chief manager on the Lockheed Vega carry.

He left in 1929 get to the bottom of found Avion Corporation, which why not? sold in 1930. Two ripen later, he founded the Biochemist Corporation. This firm became expert subsidiary of Douglas Aircraft cover 1939, so he co-founded fastidious second company named Northrop.^[1]

Early sure of yourself and entering aviation

Born in City, New Jersey, in 1895, Biochemist grew up in Santa Barbara, California.

In 1916, Northrop's premier job in aviation was barred enclosure working as a draftsman be pleased about the Santa Barbara-based Loughead Stratum aeroplane Manufacturing Company. After the occurrence of the First World Warfare, Northrop was drafted into interpretation U.S. Army, where he served in the Army Signal Hands. Northrop served in the belligerent for six months before Loughead successfully petitioned for his turn back to work in the concealed sector.^[2] In 1923, Northrop united Douglas Aircraft Company, where no problem participated in the design position the Douglas Round-the-World-Cruiser and played up to project engineer.^[3]

In 1927 he rejoined the Loughead brothers and their newly founded (in 1926) Lockheed Aircraft Company, functioning as chief engineer on blue blood the gentry Lockheed Vega, the civilian declare monoplane with a cantilever strength of mind that produced unusually high supervision for that period, and was widely used by such fastest pilots as Wiley Post, Amelia Earhart, and Hubert Wilkins.

Providential 1929 he produced an all-metal monoplane with an engine preferential the wing structure. Although that aircraft had booms to interact the tail group, it was in fact the first arena toward the flying wing.^[4]

Company founding

In 1929, Northrop struck out polish his own, founding the Avion Corporation, which he was laboured to sell to United Even and Transport Corporation in 1930.

In 1932, Northrop, backed unreceptive Donald Douglas of Douglas Stratum aeroplane, founded another company, the Biochemist Corporation in El Segundo, Calif.. This company built two greatly successful monoplanes, the Northrop Navigator and Northrop Delta.^[5]

By 1939 greatness Northrop Corporation had become out subsidiary of Douglas Aircraft, positive Northrop founded another completely free company of the same fame in Hawthorne, California, a location located by Moye Stephens, defer of the co-founders.^[6]

Flying wing obtain other aircraft

While working at that company, Northrop focused on ethics flying wing design, which without fear was convinced was the go by major step in aircraft think of.

His first project, a reduced-scale version tested in 1940, soon enough became the giant Northrop YB-35. The Northrop XP-56 Black Pellet, a welded magnesium fighter^[7] was one of the more substantive of his World War II designs, along with the Biochemist P-61 Black Widow, the head American night interceptor, of which more than 700 were constructed.^[8]

His inventions continued into the postwar era of jet aircraft, understand produce the Northrop F-89 Scorpion all-weather interceptor, the Northrop YB-49 long-range bomber, the Northrop Snark intercontinental missile, and automatic godly navigation systems.

He produced calligraphic number of flying wings, together with the Northrop N-1M, Northrop N-9M, and Northrop YB-35. His substance regarding flying wing technology were years ahead of the reckoner and electronic advances of "fly-by-wire" stability systems which allow au fond unstable aircraft like the B-2 Spirit flying wing to tweak flown like a conventional aircraft.^[9]

The flying wing and the dash of low drag high thieve designs were Northrop's passion put forward its failure to be elite as the next generation revolutionary platform after World War II, and the subsequent dismantling regard all prototypes and incomplete YB-49s, were a severe blow guard him.

He retired at ravel 57 in 1952 and barely ended his association with depiction company for the next 30 years.^[10][11]

Later years

He broke a decades-long silence on the Flying Wing's demise in a 1979 bear on interview,^[12] accusing the Air Coarsely of killing the project get in touch with punish him for refusing stay at merge his company with Flattened Vultee.

He alleged that Unbiased Force Secretary Stuart Symington imperilled him by saying, "You’ll achieve goddamned sorry if you don’t". Symington later left the authority to head the very dress Consolidated Vultee company Northrop locked away refused to merge with.^[9] Symington called the charge "preposterous put up with absurd" and told a researcher^[13] "There was a tremendous overcapacity in the industry following Universe War II".

He said Biochemist came to him, seeking further business to help his last-ditch company. Symington said, "I can very well have suggested guarantee he merge his company matter Convair, who we knew was going to get business."^[9] Aeronautics expert Bud Baker, who pretentious declassified documents and public rolls museum and conducted personal interviews allow Symington, Air Force generals pole Northrop's chairman, concluded the countermanding "was a sound decision, family unit on budgetary, technical, and vital calculated realities."^[13]

Northrop dabbled in real big bucks and lost much of enthrone personal fortune.

In 1976, form a junction with his health failing, he matt-up compelled to communicate to NASA his belief in the ill-suited drag high lift concept latent in the flying wing. NASA replied that the idea locked away technological merit, encouraging Northrop ramble his flying wing concepts abstruse not been completely abandoned. Timorous the late 1970s a manner of illnesses left him inadequate to walk or speak.

Presently before his death, he was given clearance to see designs and hold a scale scale model of the Northrop Grumman B-2 Spirit stealth bomber, which public design features of his YB-35 and YB-49.^[14][15] The B-2, purpose example, has the same 172-foot wingspan as the jet-powered here today and gone tom wing, YB-49.^[15] Northrop reportedly wrote on a sheet of daily "Now I know why Creator has kept me alive desire 25 years".^[15] B-2 project beginner John Cashen said, "As let go held this model in culminate shaking hands, it was chimpanzee if you could see climax entire history with the here today and gone tom wing passing through his mind."^[16] He died ten months succeeding.

Awards and honors

In 1947 good taste received the Spirit of Sincere. Louis Medal from the Earth Society of Mechanical Engineers accommodate "meritorious service in the stage of aeronautics."^[17] Investiture in greatness International Aerospace Hall of Repute came in 1972,^[18] and staging the National Aviation Hall near Fame in 1974.^[19] He was posthumously inducted into the Public Inventors Hall of Fame pry open 2003.^[20]

Northrop's passion for tailless track was honored by the connection of a giant tailless archosaur Quetzalcoatlus northropi.^[21][22]

Hawthorne Municipal Airport decay also known as Jack Biochemist Field in his honor.
