Higher-speed lower-consumption aircraft with symmetrical, oblique engines

The invention belongs to aircrafts and relates to a higher-speed lower-consumption aircraft with symmetrical, oblique engines, in particular to arrangement of aircraft engines. Under the reactive force created by engines blowing the air back, the aircraft is pushed to fly forward; the higher the reactive force, the faster the aircraft. The aircraft generally has two engines or four engines in symmetrical arrangement; jet holes of the engines can be set in a splayed form relative to an aircraft body. The air is blown in a bilateral areal back-flowing form instead of an original form of vertical linear back-blowing; spatial area of air pushing is increased by three to five times; the increase in the spatial area leads to increase in air resistance, the original length of air jetting is decreased from 800 meters to 200 meters, and the short length of air jetting means the increase in the reactive force of the air to the aircraft. The higher-speed lower-consumption aircraft is composed of an aircraft body 1, engines 2 and the like; the engines are 30 to 35 degrees angled to the aircraft body 1 ideally, which increases the speed by 20 to 30 percent.
