The Boeing B-47 Stratojet (Boeing company designation Model 450) is a retired American long-range, six-engined, turbojet-powered strategic bomber designed to fly at high subsonic speed and at high altitude to avoid enemy interceptor aircraft. The primary mission of the B-47 was as a nuclear bomber capable of striking targets within the Soviet ...

Improvements in the B-47's J47 jet engines (particularly water-methanol injection, where a mixture of water and methanol was injected into the engines at take off, increasing mass flow and thus the level of thrust), reduced the need for JATO (the water injection also caused the engines to emit black smoke, due to the incomplete combustion of ...

JATO (acronym for jet-assisted take-off) 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 (more specific) term RATO, for rocket-assisted take-off (or, in RAF parlance, RATOG, for rocket-assisted take-off gear).

波音 B-47「同溫層噴射機」 （英語： B-47 Stratojet）是一型擁有六具噴射發動機的長程中型 轟炸機。 它的設計目的是以高亞 音速 的速度自高空穿透 蘇聯 的防線，以 核彈 攻擊蘇聯本土地區。 B-47可以說是自 二次世界大戰 以來一個極為重要的跨時代設計。 在現代大型噴射客機上所見到幾個重要特徵，包括大型後掠翼跟安置於機翼下的發動機夾艙設計，此時都應用在B-47之上。 B-47轟炸機於1951年正式進入 美國空軍 服役。 雖然它在服役期間從未以轟炸機的角色參加過任何一 …

The Boeing B-47 Stratojet was the first swept wing jet bomber and the first to be designed to carry nuclear weapons. The design of the B-47 relied on swept wing data captured from Germany after World War II. Boeing engineers had envisioned a jet-powered plane as early as 1943.

2019年2月7日 · The notoriously slow acceleration of early jet engines gave the designers of Boeing’s revolutionary swept-wing B-47 Stratojet cause to employ JATO to help heavy B-47s quickly reach flying speed. Early B-47s were built with an internal JATO system with 18 nozzles pointing aft; others used 30 or more attachable external rockets that could be ...

The six-engine Boeing B-47 was America’s first multiengine swept-wing jet bomber. Its thin 116-foot wing was extraordinarily flexible and swept back at a 35-degree angle. Eighteen small rocket units in the fuselage provided jet-assisted takeoff (JATO), and parachutes cut its landing speeds.

2007年3月29日 · A Boeing B-47 "Stratojet" "deploys smokescreen" with a water-injection and 33 JATO rockets. Later, the JATO rack is jettisoned and the crew demonstrates the ...

2010年3月7日 · This pic is from 1954 of a Boeing B-47 making a Jet Assisted Take Off . The rather massive JATO package was a great help in getting the aircraft off the ground a lot quicker than with just the 6 wing mounted jet engines.
