What happens if thrust is greater than drag?
If thrust is greater than drag, the aircraft will speed up, and subsequently, if drag is greater than the thrust, you’ll slow down. Lift is the force that counteracts the weight of an object in order to keep it in the air.
What are 4 things that affect drag force?
Explanation: Some factors that impact the magnitude of air resistance (drag) include the size and shape of the object, the velocity of the object and the air, and other properties of the air such as its viscosity, mass, and compressibility.
Which is the most streamlined shape?
teardrop
How do airplanes use drag to their advantage?
How does drag affect an aircraft in flight? Drag is the force which delays or slows the forward movement of an airplane through the air. The more surface area exposed to rushing air, the greater the drag. An airplane’s streamlined shape helps it pass through the air more easily.
How do you reduce drag on a blunt body?
A spike in front of the blunt nose offers an effective means of such drag reduction. Flow past the spike creates a conical shock wave and remains away from the body. Flow behind the conical shock wave separates on the spike and a conical shaped re-circulation zone forms in the vicinity of the stagnation region.
Does the Reynolds number affect the drag?
Lift decreases and drag increases when Reynolds number is decreased.(2)For the airfoil with GF, Reynolds number has adverse effects on lift coefficient, while drag coefficient of the airfoil with GF has some beneficial effects compared to the airfoil without GF.(3)For high Reynolds number above critical range, decrease …
How does streamlining reduce drag?
Streamlining, in aerodynamics, the contouring of an object, such as an aircraft body, to reduce its drag, or resistance to motion through a stream of air. A moving body causes the air to flow around it in definite patterns, the components of which are called streamlines.
What is the difference between streamlined and blunt bodies?
A streamlined body is defined as that body whose surface is aligned with the streamlines, when the body is placed in the flow. A bluff body is defined as that body whose surface is not aligned with the stream-lines, when placed in the flow. • Thus, the body offers lesser resistance in terms of Viscous/Frictional drag.
