The United States hasn't had a light parachutable tank since they retired the M Sheridan in , and even then its performance was underwhelming; armor light enough to drop isn't very protective. Why do c used propellers? The C is designed to carry cargo, not move quickly. So a propeller is more efficient at moving heavier loads slower and a jet is more efficient at moving lighter loads faster? It uses a turbine powered propeller. Pure jet engines aren't efficient until a certain air speed is reached.
How much does a c cost? What is the best jobs in the Air Force? Best U. Air Force jobs Pilot. Pilots are responsible for completing missions by flying various Air Force aircraft.
Public affairs officer. Flight engineer. Security forces. Operations intelligence. Air traffic control. Tactical aircraft maintenance. Aircraft loadmaster. Can a c fly on one engine? With four 3,hp engines—soon to be uprated to 4, apiece—the C was one of the most overpowered aircraft in the military inventory.
It could literally fly on one engine. How Slow Can a c fly? How many l pallets can you stack? Can a C carry a tank? It can carry up to 42, pounds of cargo. Here are 10 things that can be transported by the C Hercules: Tanks. Can a c land on an aircraft carrier? This is a big plane for a small runway. The newer engines on the J model produce up to 4, shaft horsepower shp each though they are listed here at 4, shp , while the engines on the H model produce up to 4, shp each.
The empty weight on the J model is 75, lb and on the H model is 75, lb. So with the empty weight going down by lb and the power increasing by at least 47 shp, and improved propellers, the J model has better performance. The takeoff distance at , lb is 3, feet for the J model versus 3, feet for the H model.
The H model can take off in 1, feet at 80, lb probably closer to the weight in demonstrations , so the J model can probably do even better.
This is a significant reason for the C's performance that you witnessed. Also there are some weight limitations. Further, the crew must be specifically trained.
Any idea of a smooth landing is thrown out the window. The intent is to "plant" the wheels at about feet down the runway. That is, transition immediately from approach attitude to actually landing rather than assuming a touch-down attitude and letting the aircraft float down to the runway.
The nose gear is pushed to the ground and the instant the wheels are on the ground the props are thrown into full reverse, now pushing air forward. At the same time the pilot puts all his might into mashing the brakes. He would "stand on the brakes" as we say. The yoke is also pushed full forward which puts as much weight as possible on the landing gear. The anti-lock brake system is critical here, preventing skidding out of control and blown tires. In Vietnam, in combat conditions, pilots would put the props in reverse before touching down.
If you've seen the video on YouTube of a C landing on an aircraft carrier, they did it there too. The performance boost of the J models thanks to the new prop and engine is amazing vis-a-vis the older models. But fundamental airframe limitations are still there. Nonetheless more blades 6 vice. An empty airplane with a light fuel load of course maximizes the short takeoff and landing performance. Not blown flaps. Just because the props push air over the wing does not make it blown flaps.
Otherwise, yes, the C was given lots of flapage precisely for this purpose. This combines into a takeoff distance of m at 70 ton, and at the air show they would have kept the plane nearer the empty weight which is half that which shortens the needed takeoff length.
To compare the Lockheed C Hercules has a slightly longer takeoff distance at the same weight but only needs half that when the weight is reduced to 36 ton.
These propeller blades can change their pitch which can reverse the thrust direction, plus the wheel brakes even large jets use mostly wheel brakes see this answer.

My questions are: How does such a massive plane manage to take off in short distances?
Is it because it has four engines? During landing, I couldn't see any thrust reverser as in commercial jets in play. What tech does it use to stop so quickly? Improve this question.

Would possibly be shorter given extremely low weight and high headwind conditions. Show 2 more comments. Active Oldest Votes.
