Specification Brand : FYYKXWD BulletPoint1 : Structure:The aircraft lift principle demonstrator consists of an aircraft wing section model, a blower and a base. BulletPoint2 : Instructions:Connect the power supply to the base terminal to make the blower work. The blower blows the wing model to make the wing fly. BulletPoint3 : Principle:The main reason for the aircraft's lift and gliding effect is the main part of the aircraft's wing, the impact on the aircraft, the wing is the main bearing for the lift, which is of great significance to the flight. BulletPoint4 : As the wing passes through the air, the flow rate of the air above and below the wing will change. The airflow speed above the wing is slow and the pressure is small, while the air in the lower space is fast and the pressure is high. The pressure difference between the two is the lift of the aircraft. BulletPoint5 : Quality service:We attach great importance to customer experience, so you can us if you have any questions, and we will get back to you within 24 hours!
