![]() So, hypothetically speaking, if a spacecraft reached. 5c would have to follow to expose the occupants to not more than one g. Jet fighters fly faster and make tighter turns (larger #v#, smaller #r#) than commercial aircraft so the g-forces are larger.īecause you're thinking about spaceflight at relativistic velocities, you might find it amusing to try calculating the diameter of the circular path a spaceship traveling at. In the simplest case the object is following a circular trajectory and the g-force will be given by #v^2/r# where #r# is the radius of the turn and #v# is the speed. Air Force fighter pilot Christine 'Grinder' Mau examines some. #FIGHTER PILOT G FORCE TV#It's the same force that keeps a string taut when you tie a weight to the end of the string and swing it. Season 1 Episode 25 Former US Air Force Fighter Pilot Breaks Down 12 Fighter Pilot Scenes From Film & TV About Credits Former U.S. The g-force experienced in a turning aircraft (or car, or just about anything else moving on a curved path) is just plain ordinary garden-variety centrifugal force. If a fighter pilot is cruising along with doing such maneuvers, there will be no extreme-g events during the flight. It's often when pulling out of a high-speed dive that the g-forces build to such an extent that the pilot could lose consciousness, unless special means are taken to prevent such an event. In order to evade an enemy attack or to gain an advantage on a flying target, fighter pilots often engage in high speed dives and turns. For what its worth, skeletal injuries due to G forces are so rare that they arent even briefed during training. Would such forces act the same way in space? And if so, would there be a way to balance the forces without affecting the motion of the spacecraft? A force field of a sort, maybe?įlying in a supersonic fighter during high-speed maneuvers is a very different experience to flying in a commercial jet liner. The danger to high G-forces in the vertical axis is that the blood is pulled from the brain to the lower extremities causing a form of hypoxia commonly referred to as GLOC, or G Induced Loss of Consciousness. The main reason I ask this question is because I believe (I hope, at least) that one day we will be able to reach relativistic speeds with manned spacecraft to venture the stars. Why does this happen? I've read it in many science-fiction novels as well, about how inertia and increased G-force due to great velocity can be, well, harmful to a human being. It is known that, at high velocities, pilots in super-sonic jet fighters, or just standard fighter jets that can achieve incredibly high speeds, experience an increased G-force pressing against them in the cockpit. So, here's a question from you from an aspiring scholar. I always try and ponder on questions about everyday aerodynamics and physics. Hi! I'm a high school student, aspiring to pursue a career in Astronautical Engineering. ![]()
