- During takeoff and landing, the flaps on the back of the wing extend downward from the trailing edge effectively altering the shape of the wing. This change enables it to divert more air generating more lift. This change also increases drag, which helps a landing airplane slow down while requiring more thrust during takeoff.

- Phoenician Navigation. The Phoenicians were masters of sea travel covering great distances in their ships of trade and war. They were the first people to venture to the western Mediterranean and beyond the Straits of Gibraltar to the Atlantic coasts of Africa and Europe.he second type of navigation was deep-sea navigation. This was used when the Phoenicians were sailing over open water to destinations that were very far from the port of departure. While they would also keep land in sight, they were much farther out in open water.

- In simple terms, planes are held aloft by lift, the force generated when air flows over and under an airplane wing simultaneously. Air travels faster over the curved top of the wing than below it.

Downforce D is downforce in newtons; W is wingspan in meters; H is the thickness of the section in meters; F is lift coefficient; ρ is air density in kg/m³; v is velocity in m/s; In certain ranges of operating conditions and when the wing is not stalled, the lift coefficient has a constant value: the downforce is then proportional to the square of airspeed.

Lesson: What Makes Airplanes Fly? Vocabulary/Definitions. 1  Acceleration: A change in direction, or speeding up or slowing down. 2  Aeronautical engineer: A person who studies the forces involved in flight. 3  Drag: The force that slows an airplane or parachute down. 4  Force: Something that acts from the outside to push or pull an object. For example, an adult pulling a child in a wagon exerts a force upon the wagon. Lift: The force that pushes an airplane up into the air. Lift is caused by the shape of an airplane's wings.

4 Lift, Thrust, Weight, and Drag The relative wind acting on the airplane produces a certain amount of force which is called (unsurprisingly) the total aerodynamic force. This force can be resolved into components, called lift and drag, as shown in figure 4.1.

The Four Forces 1 Lift is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.  Thrust is the force that propels a flying machine in the direction of motion. Engines produce thrust.

How A Propeller Generates Thrust In order to accelerate an airplane, thrust must be greater than drag. By increasing engine power and propeller revolutions (RPM), air is increasingly accelerated across the blades, creating a stronger pressure differential, pulling the airplane forward. This accelerates the airplane, but is limited by thrust available.

- The opposite forces of flight are equal only when a plane flies level at constant velocity. The opposite forces of flight are not always equal. For instance, as a plane climbs, its weight is equal to a portion of the lift force and a portion of the thrust force. In this situation, the opposite forces of flight are no longer equal to one another.

What Makes Paper Airplanes Fly? Thrust and lift are two other forces that help your plane make a long flight. Thrust is the forward movement of the plane. The initial thrust comes from the muscles of the pilot as the paper airplane is launched. After this, paper airplanes are really gliders, converting altitude to forward motion.

What Is the Force That Slows Down the Movements of an Object Through a Liquid or Gas? What is the force that slows down the movements of an object through a liquid or gas? A: The force that slows down the movements of an object through a liquid or gas is known as drag, or air resistance. In some cases, this force is also referred to as friction, but classically, friction occurs in solid objects. Continue Reading.

Hawaiian Airlines jet carrying almost 300 people causes chaos at Japanese airport and closes a runway when all its tires blew out on the tarmac during emergency landing Hawaiian Airlines Airbus A330 forced to make emergency landing in Japan. Eight tires blew out on the plane when it landed at Haneda Airport. Emergency landing was caused by problems with the hydraulic system. A runway was closed and flights were cancelled as a result of the landing.

Speed of a Commercial Jet Airplane This great rearward force is balanced with an equal force that pushes the jet engine, and the airplane attached to it, forward. Thrust is the force that propels an airplane forward through the air. It is provided by the airplane's propulsion system in this case by a jet engine. Drag is a force acting on all airplanes.

- Aerodynamics and G forces. Aerodynamics refers to the physics of flight: the forces thet produce, affect and control flight. The most important forces for pilots are thrust, lift and drag. Thrust. Thrust is the force that moves an object, such as an aircraft, along a specific path. It is the force that overcomes the inertia of an object due to gravity and the resistance of an object moving through air. In aircraft, thrust comes from propellers or jet engines.

How Do Helicopters Fly? Lift, Drag, Thrust and Weight. The force needed to keep an aircraft in the air is called ‘Lift.’ Lift is produced by air flowing over the wings. The shape of the wings is designed so that the air flowing over the top surface has to travel further, and it therefore travels faster, than the air under the wing.

How fast is a jet plane? What are the effects of gravity on the pilot of a fast jet plane? Gravity has the same effect on a pilot as any other object. If a plane is flying very fast, the gravity is still pulling the aircraft and the pilot down towards t … he earth. If the plane performs maneuvers, then the gravity may seem negligible but it still is pulling down.

How do the forces of lift drag gravity and thrust affect the flight of an airplane? As thrust increases lift increases and the plane rises as lift overcomes the downward pull of gravity. 3. Gravity - the force that pulls objects back to Earth. In order to have an object like a plane rise higher the Lift force must be stronger than the pull of gravity.

- How Airplanes 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. This motion is produced by the Thrust of the engine(s).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.his motion is produced by the Thrust of the engine(s). 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.

TEACHERâS GUIDE For AEROSPACE: THE JOURNEY OF FLIGHT Aerodynamics Aerodynamics is the study of forces and the resulting motion of objects through the air. Studying the motion of air around an object allows us to measure the forces of lift, which allows an aircraft to overcome gravity, and drag, which is the resistance an aircraft “feels” as it moves through the air. Everything moving through the air (including airplanes, rockets, and birds) is affected by aerodynamics. In this section, we will explore how lift and drag work at both subsonic speeds—slower than the speed of sound—and, later, at supersonic speeds—faster than the speed of sound.

- At 0 mph, The entire train effectively has a drag force slowing it down of roughly 40,000 lbs (steel on steel has much lower friction than say, rubber on asphalt). Since it is stopped, the static friction might make that as high as 100,000 lbs.

Air in Motion Search this site: As an airplane moves through the air, its wings cause changes in the speed and pressure of the air moving past them. These changes result in the upward force called lift. To understand lift, you first have to understand how air (a gas) behaves under certain conditions.
