Inventory Of 60 Major Inventions Of New China (Two)

4. China's first jet plane

Brief introduction of the invention: the jet engine used by jet aircraft is driven by the backlash of the gas generated by the combustion of fuel to make the aircraft fly forward. It can make the aircraft gain greater thrust. The first jet plane of our country was born in 1956.

Impact: our first fighter jet, J. 5, was successfully completed, ending the history of China's failure to manufacture jet fighters.

July 19, 1956 is an unforgettable day for us.

China's first jet fighter 5, "Zhong 0101", arrived at Yu Hong airport in Shenyang, and successfully flew to the sky of the motherland.

The test proves that the performance and data of special equipment, engine and so on are all up to the requirements of the flight test outline at the maximum speed and maximum height of "Zhong 0101" aircraft.

In September 8th, the national acceptance Committee held the acceptance and signing ceremony at the plant and named it "56 machine" (later named "annihilation 5").

5. the first high-precision electric coordinate boring machine in China

Introduction: in July 1957, the Kunming machine tool factory successfully manufactured the first high-precision electric coordinate boring machine in China.

6. China's first 1150 mm blooming mill

Brief introduction of the invention: in October 1957, the second blooming mill of Anshan Iron and Steel Co., Ltd. successfully manufactured the first 1150 mm blooming mill in China.

7. China's first homemade limousine

Introduction: in April 1958, the first homemade car in China's history was born in FAW, named "Dongfeng", because President Mao Zedong had a famous judgement on the world situation at that time: "the east wind prevailed over the west wind".

Dongfeng car engine is modeled on Mercedes Benz -190, chassis and body reference "Xi card - Wei Di Di": the headgear is a golden dragon, because the world often symbolizes China by dragon.

Impact: the first "Dongfeng" brand homemade car production, marking the Chinese automobile industry technology level has improved.

Since then, FAW's technical level has gone up to a new level, and China's first "red flag" brand car has been successfully created.

In order to offer a gift to Daqing in the ten years of new China, FAW has selected 33 cars and two open inspection cars to Beijing.

The red flag car has added a new bright spot to Daqing in the ten years of new China.

The red flag car passing through the capital street became a unique landscape at that time.

8. China's first computer

Introduction: in August 1, 1958, China's first digital computer -- the 103 machine was born, with an average speed of 30 times per second.

The core memory is improved and the computing speed of the computer is increased to 1800 times per second.

Beijing cable power plant has produced 36 units, named djs-1 computers.

Impact: in April 1957, China ordered M-3 computer and computer graphics data via government channels.

On the basis of Surveying and obtaining drawings, the development work began.

Led by Zhang Zichang and Mo Sheng Sheng, we organized the M-3 (code 103) computer engineering group.

Through the efforts of all the developers and the close cooperation of Beijing cable power plant, the first digital electronic computer in China was successfully developed in August 1, 1958.

The electron tube computer with the speed of 30 times per second fills the gap of modern computer in our country.
