1. Boeing Model 450 B-47 Stratojet е бил средно-бомбардировач с дълги разстояния, шест двигателя, задвижван с реактивни двигатели, създаден да лети с висока дозвукова скорост и на голяма надморска височина. Той е предназначен предимно за хвърляне на ядрени бомби върху Съветския съюз. Със своите двигатели, носени в шушулки под метеното крило, B-47 беше основна иновация в дизайна на бойните реактивни самолети след Втората световна война и помогна да се стигне до модерни реактивни самолети.

The **Boeing B-47 Stratojet** was a pivotal American strategic bomber that served as the backbone of the U.S. Air Force Strategic Air Command (SAC) during the Cold War era of the 1950s. It was a revolutionary aircraft that set the standard for modern jet design by introducing several key features to large aircraft.
Design Innovations
Swept Wing Configuration
The B-47 was the first large aircraft to feature highly **swept wings** (35 degrees). This design was crucial for achieving high subsonic speeds and avoiding the excessive drag associated with straight wings near the sound barrier. The wings were thin and highly flexible.
Pod-Mounted Engines
The aircraft utilized **six turbojet engines** mounted in streamlined pods beneath the wings (two twin pods inboard and two single pods outboard). This configuration reduced structural weight, lessened wing flutter, and became the blueprint for virtually all subsequent jet aircraft, including commercial airliners.
Bicycle Landing Gear
Due to the thin wing structure, which couldn’t accommodate main gear, the B-47 used a “bicycle” arrangement: two sets of main wheels in tandem along the fuselage centerline, supplemented by small **outrigger wheels** that retracted into the inboard engine pods.
Primary Role and Service
The Stratojet was designed as a high-altitude, high-speed nuclear bomber, intended to penetrate Soviet airspace faster than interceptors could react. Over 2,000 units were manufactured.
- Роля: Medium-range **nuclear deterrent** for the United States during the 1950s.
- Performance Quirk: Early jet engines required additional thrust for takeoff when fully loaded; consequently, B-47s often carried JATO (Jet-Assisted Take-Off) rockets.
- Landing Quirk: Its sleek, aerodynamically clean design meant it struggled to slow down for landing, requiring the use of a **drogue parachute** to increase drag.
- Варианти: Beyond its bomber role, the aircraft was adapted for critical **reconnaissance** missions (RB-47), electronic intelligence (ELINT), and weather reconnaissance (WB-47).
- Legacy: Although its bomber role ended by the mid-1960s (replaced by the B-52), the B-47 is remembered as the aircraft that bridged the gap between propeller-driven bombers and the modern jet age, influencing all subsequent large jet aircraft design.

The Air Force used the B47 as a weather platform in the 1960/1970’s. On the west coast they operated out of McClellen AFB.
