Airplanes fly due to lift generated by their wings as they move through the air. Thrust from the airplane's engines propels the craft forward, overcoming air resistance. When the thrust exceeds drag and the lift exceeds weight, the airplane gains altitude. Helicopters fly using rapidly rotating rotor blades that function like wings to provide lift without requiring forward movement through the air. Jet engines also propel aircraft using Newton's third law - gases ejected from the rear of the engine push the plane forward with an equal force.

How do airplanes fly jarrod
Airplanes fly due to the pressure differences created by the movement of air over and under the wing. Faster moving air over the wing results in lower pressure, lifting the wing up. Plane controls like the ailerons, elevator, rudder allow pilots to roll, pitch, and yaw the plane to control its direction. The document also lists the top 10 biggest and fastest planes in the world, with the Antonov An-225 being the largest and the Falcon HTV-2 being the fastest.
How does a plane fly?
Air transportation is the safest form of transport. There are approximately 200,000 flights per day worldwide. The presentation discusses how airplanes fly through aerodynamic forces of thrust, drag, lift, and weight. It explains how jet engines produce thrust to propel planes and how the shape of wings generates lift. Control surfaces like ailerons, elevators, rudders, and flaps help pilots control the aircraft during different phases of flight such as takeoff, cruise, descent, and landing.
The science behind how planes fly
The document discusses the science behind how planes fly. It explains that four main aerodynamic forces - lift, gravity, thrust, and drag - work together to enable flight. Lift is generated by the wings and counteracts gravity. Thrust from the engines overcomes drag. While Bernoulli's principle and Newton's laws both play a role in generating lift, modern research indicates lift requires power to divert air downward which creates an equal reaction upward. The angle of attack and design of the wings are also important for maintaining proper lift. Pilots control various surfaces like the ailerons, elevators, rudder, and flaps to maneuver the plane during flight.

Aircraft & dynamics of flight
The document provides information about aircraft and aviation. It discusses the history of aviation from early pioneers to modern aircraft. Various types of aircraft are described including propeller, jet, and rotorcraft. Details are given about aircraft engines, how wings create lift, and how pilots control planes. The document also covers topics like overcoming the sound barrier, aviation education in Bangladesh, and career opportunities in the aviation industry.
Principles of flight_chapter_1
Lift is generated when air flows over an airfoil such as a wing. The air traveling over the top of the wing must move faster than the air on the bottom, lowering the air pressure above and raising it below, which creates an upward force called lift. Several factors affect the amount of lift generated, including airspeed, angle of attack, air density, and wing shape and area. For an aircraft to fly, the lift must equal or exceed the aircraft's weight to allow it to climb, remain level, or descend depending on the balance between lift and weight.
Unit 1 Basic Aerodynamics ATPP 200
The document discusses the four forces of flight - lift, weight, thrust, and drag. It explains that lift is produced by the interaction of air moving over an airfoil shape according to Bernoulli's principle. The angle of attack and airspeed determine the amount of lift generated. For steady level flight, the opposing forces of lift and weight and of thrust and drag must balance. Induced drag is caused by lift and increases with higher angles of attack needed for slower flight. Exceeding the critical angle of attack causes a stall from airflow separation over the wing.
Lift of a wing
Lift is an aerodynamic force produced by the motion of an airplane's wing through the air. According to Bernoulli's principle, lift is generated because the airflow is faster and the pressure is lower over the curved top surface of the wing compared to the bottom. However, this explanation is flawed because a wing would still produce lift even if upside down. The correct explanation is that the wing exerts a downward force on the air and the air exerts an equal and opposite upward force on the wing according to Newton's Third Law of Motion.

Physics Presentation Final 1
Helicopters generate lift through rapidly spinning rotor blades. As the blades spin, they push air downwards, creating higher pressure below the blades and lower pressure above. This pressure difference results in an upward force called lift. Pilots control a helicopter's movement through control devices like the collective, cyclic, and anti-torque pedals, which alter the rotor blade angles and direction of thrust. Helicopters can hover, fly in any direction, and carry heavy loads, but are more complex than airplanes due to the need to counteract torque from the main rotor.
Aerodynamics
This document discusses key concepts in aerodynamics including lift, drag, thrust, and Newton's laws of motion. It explains that aerodynamics is the study of how objects move through air and are affected by forces. Lift enables airplanes to fly by generating force from wing movement. Thrust provides forward propulsion from jet engines. Drag prevents forward motion and must be overcome by thrust. Newton's laws of motion form the basis for calculating these aerodynamic forces.
Principles of flight_chapter_6
Helicopters generate both lift and thrust using rotor blades that spin around a central axis, rather than fixed wings. Pilots control the lift and direction of travel through the collective pitch and cyclic pitch controls, which respectively alter the angle of the rotor blades to increase lift or tilt the disc in the desired direction of thrust. The torque reaction from the spinning rotor is counteracted by a tail rotor that pushes the fuselage in the opposite direction to prevent it from spinning, and pilots can control yaw using the tail rotor pitch.
Physics Presentation Final

Airplanes types and basic principles.ppt
Airplanes fly due to four main aerodynamic forces: thrust, which propels the plane forward and overcomes drag; lift, which is generated by the wings and counteracts the downward force of weight. In straight and level flight, thrust equals drag and lift equals weight. The wings generate lift through faster air flow over the top surface, creating lower pressure that effectively "sucks" the plane upward. Additional control surfaces like the horizontal and vertical stabilizers, rudder, ailerons and elevators help control the plane's movement.
Understanding aerodynamics teacher presentation.pptx
This document discusses aerodynamics and how aerofoils allow aircraft to fly. It explains that lift opposes weight and is increased by aerofoils while drag opposes forward motion. The document provides instructions on making a simple paper aerofoil by folding paper with an upward curve and testing how airflow interacts with different shapes.
helicopter dynamics
1) A helicopter uses rotating wings called blades to fly unlike airplanes which use fixed wings. It can take off and land vertically.
2) The four fundamentals of helicopter flight are straight-and-level flight, turns, climbs, and descents. Forces acting on a helicopter include lift, weight, thrust, and drag. It also experiences unique effects like pendular action, coning, and gyroscopic precession due to its rotating blades.
3) Helicopters can take off, land, and hover vertically. During takeoff, the main rotor tilts forward to generate horizontal thrust to accelerate. Hovering requires enough lift and thrust to equal the helicopter's weight and drag produced by
Aviation history
This document provides an overview of the key components and principles of aircraft flight. It discusses Newton's laws of motion, Bernoulli's principle, the major parts of an airplane including the fuselage, wings, empennage, and powerplant. It describes the primary control surfaces - ailerons, elevators, and rudder - and how they control the roll, pitch, and yaw of an airplane. The document aims to explain the basic scientific principles that allow airplanes to fly and be controlled through the air.
AIR TRANSPORTATION
The document discusses various aspects of commercial airline travel, including:
- Types of airline flights such as nonstop, direct, and connecting flights.
- Components of an airplane like the fuselage, wings, engines, horizontal and vertical stabilizers, and control surfaces.
- Types of airline seats and how their size is measured by pitch (legroom between rows) and width (distance between armrests).
- Pros and cons of different seating locations on a plane from the front to the back of coach class.
Basic Principles of Flight.pptx
The document discusses the basic principles of flight, including the four main forces acting on an airplane (lift, weight, thrust, drag), how flight controls like the elevator, ailerons, and rudder work to control the aircraft, aerodynamic concepts like Bernoulli's principle and how wings and propellers generate lift and thrust, the basics of take-off, flight, and landing, and maneuvers, turns and circuit patterns. It provides explanations of these fundamental aspects of flight to build knowledge for pilots.
Flying of aeroplanes
Planes are able to fly due to two key forces: thrust and lift. Thrust from the plane's engines overcomes drag and allows for horizontal movement. Lift is generated by the specially designed wings, which cause air to move faster over the top of the wing. This lower air pressure above the wing compared to below provides an upward force called lift. When lift exceeds the plane's weight, the plane is able to take off and fly. Landing occurs when the wings are adjusted to reduce lift by slowing the airflow over the wings.
FLYING IS FUN
Flying is fun according to the document. It discusses how over 100,000 people in the US each year learn to fly small aircraft for reasons like recreation, business, and as a stepping stone to a career in piloting. The document also provides basic information on how airplanes fly, describing the four main forces of lift, gravity, thrust, and drag. It outlines the basic parts of an airplane like the wings, tail, landing gear, and control surfaces that allow pilots to direct the aircraft.
How Does an Aircraft Fly?
It is most important popular question that most of people want to know that how an aircraft fly. In this presentation, there are some significant points which focus on an aircraft remains keeps in the air.
Parts of an aircraft
The document defines and explains the basic components of a typical aircraft, including:
- The fuselage, which contains the crew and payload.
- The wing, which produces lift and is made of two halves connected by the fuselage.
- The engine, which can be piston-driven or jet-powered.
- Horizontal and vertical stabilizers, which provide stability and are made of airfoil cross-sections.
It also describes basic control surfaces like the elevator, rudder, and ailerons, and additional components such as flaps, the cockpit/cabin, landing gear, and trim tabs.
AEROPLANES CREATING LIFT BY GIRISH HARMUKH
The document provides an overview of airplanes, including their history, key concepts and principles of flight. It discusses the four main forces acting on a plane - weight, lift, drag and thrust. It explains how lift is generated through two perspectives: Bernoulli's principle involving pressure differences, and Newton's view involving momentum transfer between the air and wing. Factors affecting lift such as airspeed, density and wing shape are also covered.
Principles of Flight_FINAL.pptx
There are 4 main forces that act on an aircraft in flight: lift, weight, thrust, and drag. Lift opposes weight and allows the aircraft to fly. Thrust opposes drag and propels the aircraft. Key factors that influence lift include airspeed, wing shape and angle of attack. Proper balance of these forces is required for steady level flight. The document also discusses airfoils, flight control surfaces, Newton's laws of motion, and Bernoulli's principle which are important aerodynamic concepts related to how aircraft produce and control lift.
Principles of Flight_FINAL.pptx
There are 4 main forces that act on an aircraft in flight: lift, weight, thrust, and drag. Lift opposes weight to allow flight. Thrust opposes drag to overcome air resistance and allow forward motion. An aircraft's pitch, roll, and yaw are controlled by elevators, ailerons, and rudders respectively. Airfoils generate lift through their interaction with airflow as described by Bernoulli's principle and Newton's laws of motion. Key factors that influence lift are airspeed, angle of attack, and wing design/surface area.
6.05 Lift and Drag.ppt
Bernoulli's principle states that as the speed of a fluid increases, the pressure decreases. Airfoils are shaped to take advantage of this by making the air flow faster over the top surface, creating lower pressure and lift. As angle of attack increases, lift increases but drag also increases. Parasite drag is caused by the shape of the aircraft while induced drag is caused by the parts that produce lift, like wingtips. Streamlining the aircraft reduces drag to maximize flight distance or efficiency.
6.05 Lift and Drag.ppt
Bernoulli's principle states that as the speed of a fluid increases, the pressure decreases. Airfoil shapes take advantage of this by making the air flow faster over the top surface, creating lower pressure and lift. As angle of attack increases, lift increases but drag also increases. Parasite drag comes from parts not contributing to lift like the landing gear. Induced drag is caused by parts producing lift and cannot be eliminated. Streamlining the aircraft reduces drag to improve efficiency.
Lift and Drag.ppt
1. The document discusses the theory of flight, including Bernoulli's principle, which explains how airfoils generate lift using differences in air pressure. It also covers key terms like angle of attack, center of pressure, and types of airfoils and drag.
2. The two main types of drag are parasite drag, which is caused by the shape of the aircraft, and induced drag, which is caused by the parts of the aircraft that generate lift. Induced drag cannot be eliminated.
3. As angle of attack increases, lift increases but drag also increases. Maintaining a high aspect ratio can help reduce induced drag. Wingtip vortices are swirling currents of air that form at the ends of wings
6.05 Lift and Drag.ppt
1. The document discusses the theory of flight, including Bernoulli's principle, which explains how airfoils generate lift using differences in air pressure. It increases over the upper surface and decreases over the lower surface.
2. Key airfoil terms are defined, such as angle of attack, relative airflow, and center of pressure. The document explains how increasing the angle of attack increases lift but also drag.
3. Different types of airfoils and drag forces are covered, including parasite drag from skin friction and form, and induced drag from generating lift. Wingtip vortices and streamlining aircraft are also summarized.

How aeroplanes fly - By Nathan
- 1. How Airplanes Fly My name is Nathan
- 2. Why air crafts fly • Airplanes fly because they are able to generate a force called Lift which normally moves the airplane upward. Lift is generated by the forward motion of the airplane through the air.
- 3. What the thrusts do • His motion is produced by the Thrust of the engine's.
- 4. how aeroplanes lift off • The figure below is a simple diagram of the four forces acting on an airplane – Thrust, Lift , Drag and Weight. Drag is the force produced by the resistance of the air to the forward motion of the airplane. Swish your hand rapidly side-to- side and you will feel that resistance on your hand.
- 5. Weight • Weight is the force created by the pull of gravity toward the center of the earth. You will feel the effect of this force if you jump up from the floor. • Your weight will force you back down.
- 6. How airplanes function • When the Thrust produced by the engine's) is greater than the force of Drag, the airplane moves forward. When the forward motion is enough to produce a force of Lift that is greater than the Weight, the airplane moves upward. • • While any part of the airplane can produce Lift, the most Lift comes from the wings.
- 7. Aircraft and helicopter • Fixed and Rotary WingFixed and Rotary Wing AircraftAircraft Now you are Now you are probably thinking thatprobably thinking that helicopters do not need tohelicopters do not need to move forward in order to fly,move forward in order to fly, and you are right. This isand you are right. This is because helicoptersbecause helicopters are "rotary wing aircraft,"are "rotary wing aircraft," meaning that the rotor which ismeaning that the rotor which is turned around rapidly by theturned around rapidly by the engines) is shaped like aengines) is shaped like a narrow wing and providesnarrow wing and provides the the LiftLift necessary to necessary to overcome the overcome the WeightWeight of the of the aircraft. This is different than aaircraft. This is different than a "fixed wing" aircraft where the"fixed wing" aircraft where the wings are attached to thewings are attached to the fuselage (fixed) andfuselage (fixed) and the the ThrustThrust of the engines) of the engines) moves the plane forward tomoves the plane forward to generate generate LiftLift. Tilting the rotor. Tilting the rotor allows the helicopter to moveallows the helicopter to move forward and backward or side-forward and backward or side- to-side.to-side.
- 8. How is Thrust Generated? • There are two basic types of airplanes - propeller driven planes and jet planes. • Photograph Used by Permission of Jim Collins Copyright 2005 • F4U Corsair Showing Propeller • To be continued
- 9. Propellers are shaped just like the wings, and also generate lift, except that the lift is forward instead of up and is called thrust. Each propeller is made up of two or more blades. The first propellers were made of wood, but now most propellers now are made of metal. The F4U Corsair is a propeller driven aircraft.
- 10. What is different about Jet • Jet Planes - Jet planes do not have propellers. Instead, they have jet engines that move the airplane forward through another physical principal discovered by Sir Isaac Newton (1642 - 1727). This is Newton's Third Law of Motion - "For every action there is an equal and opposite reaction." You can think of a jet engine as a tube in which a liquid fuel (like the fuel diesel trucks use) is burned at high pressure with air from a compressor. The resulting heat forces the gases out of the back of the tube at high speed. In accordance with Newton's Law, an equal force is applied in the forward direction, moving the engine (and the plane it is attached to) forward. • To be continued
- 11. These are simple explanations, and the real systems are complicated machines that are designed by specially trained engineers. The end
