..................... After we discovered how the shape of the wing's airfoil created lift force which were based on Bernoulli's principle and how to make use of it , now we take the next step of analyzing  how the shape and structure of the wing itself contributed on the performance of the aircraft, in which how the aerodynamic advantages and dis-advantages of each of the following shape and structure.   PART.2  "THE SHAPE"    W hen we talk about the aircraft wings shape, we are actually talking about the model of the wind flows that flows around it. As we know that to be an effective lift force, the wings must produce enough pressure on the underneath and smoother flow at the top of the wings, this however only focuses on the wings cutaway structure in a one sided point of view, this second part however will focuses on the stream flowing around the wings at the top point of view on an aircraft. To make it clear let me show you an example of top viewed...

PROLOG   Have you ever wonder what would an aircraft will be if the wings were absent?... why would a wing so important that various models of wings had been created through times...? or why would an aircraft engineer assemble's those aircraft with wings, which actually adding weight through out the aircraft..? we'll those question were running through my head every times, so I decide to search for answers. and here's it the answers.       " The design and analysis of the wings of aircraft is one of the principal applications of the science of  aerodynamics , which is a branch of  fluid mechanics . The properties of the airflow around any moving object can - in principle - be found by solving the  Navier-Stokes equations  of  fluid dynamics . However, except for simple geometries these equations are notoriously difficult to solve.   Fortunately, simpler explanations can be described." (source: wikipedia).   "Good ...

#Video THE AERODYNAMIC'S OF FLIGHT

  In 2015 the documentary of all Avgeeks "Aviation The Invisible Highway" will be launched, the documentary represent we Avgeeks, our passion,hopes and knowings.

  During the second world war, the Japanese Imperial Navy developed a secret weapons called the "I-400", the machine itself is part of Adm.Yamamoto masterplan after the attack on Pearl Harbor, during the attack the Japanese humiliated the strong U.S naval base in the Pacific Hawaiian island and cause heavy damage's. The other plan of Yamamoto is to attack and terrorize the mainland city of the United States and force the U.S to capitulate. During the time after the attack occurred, the U.S navy were on the peak of alert, mean's that any attempt to attack the U.S mainland by the Imperial Japanese fleet is considered to be an impossible mission. The Admiral himself decided that the attack would be done by the submarine's which would sneak under the depth of the ocean and the U.S forces patrol above, he would use the submarine to execute an "hit and run" tactics to the U.S western coast and cities,which in his mind would deteroriate the U.S means of an all ...

  I've been working on this posting for long time in my mind...sooo. I decide to post it,most of this posting are theories about the force that works on an airplane,since I've been very interested in aviation for the last 5 years ( I started to recognize planes and aviation things since elementary), I do hope that this posting will help me to understand more about airplanes.   Part.1    Weight forces.  The weight force of the aircraft is is influenced by the mass of the plane combined to the gravitational forces of the earth ( about 9,81 m/s2).   That means that W=m.g "the gravity is influenced by the sheer size of the planet!"    This means that the vector of the force goes down.      Part.2   Lift forces.  The lift force is caused by the wings of the plane. The wings airfoil structure allow the air to flow smoothly and generates lift because the layer below is slimmer than the upper side of the wings which c...
