Space travel is tricky work that takes careful calculations and even more careful actions when situations get tough. After the Soviet Union launched Sputnik in 1957, the United States entered a fierce competition with their Communist rivals for dominance in space. The ensuing space race was filled with many notable successes – including American astronauts walking and playing golf on theContinue reading “Top 5 deadliest Disaster of SpaceFlight ever happened!!”

HOW A MILITARY AIRCRAFT IS RECOGNIZED!!??
Aircraft recognition is a visual skill taught to military personnel and civilian auxiliaries since the introduction of military aircraft in World War I. It is important for air defense and military intelligence gathering. Aircraft recognition generally depends on learning the external appearance of the aircraft, both friendly and hostile, most likely to be encountered. TechniquesContinue reading “HOW A MILITARY AIRCRAFT IS RECOGNIZED!!??”
SINCE AN INCEPTION TO A BREAKTHROUGH DEVELOPMENT!!!…
THE BEGINNING: All are just in matter of time and minds. It took more than thousands of years to conquer from land to travel in sky. But it took just a span of 50 years to conquer space from sky. From carrying satellites in bullocks to carrying humans to space ISRO reached a marvellous heightContinue reading “SINCE AN INCEPTION TO A BREAKTHROUGH DEVELOPMENT!!!…”
EVER WONDERED WHAT PRODUCES LIFT IN AN AIRCRAFT RATHER THAN A FUEL!!?
An AIRFOIL produces a lifting force that acts at right angles to the airstream and a dragging force that acts in the same direction as the airstream. What is an Aerofoil in general!? An airfoil or aerofoil is the cross-sectional shape of a wing. The lift on an airfoil is primarily the result of its angle of attack. This force is knownContinue reading “EVER WONDERED WHAT PRODUCES LIFT IN AN AIRCRAFT RATHER THAN A FUEL!!?”
HOW DOES AN AIRCRAFT ACQUIRE MOTION IN CLOUDS!!?
Stability and control are much more complex for an airplane, which can move freely in three dimensions, than a vechicle in land like cars or in water like boats , which only move in two dimensions . A change any one motion can affect other two. Four forces of flight are Lift – upward DragContinue reading “HOW DOES AN AIRCRAFT ACQUIRE MOTION IN CLOUDS!!?”
DOES MASS HAVE ANY ROLE IN ROCKET PROPULSION?
The Mass of a Rocket is important for two reasons : An object with less mass accelerates more quickly. An object with more mass has more gravitational force acting on it. To understand these ideas, it is useful to think of objects moving in a horizontal direction before thinking about the vertical motion of a rocket. Horizontal Rocket Motion:Continue reading “DOES MASS HAVE ANY ROLE IN ROCKET PROPULSION?”
