The grounding rod is used to dissipate the build up of static electricity on the helicopter so the soldiers who attach the loading slings won't be shocked. The soldiers are from A Company Headquarters and Headquarters Detachment Task Force 47 and the Chinook is attached to the 501st Aviation Battalion.
it's a refueling probe, so they can be refueled mid-air without having to worry about the helicopter's blades.
That's the pitot tube. It is an air pressure sensor used to measure airspeed.
If the pole pokes out the front, it is a refuelling probe. During long search and rescue missions (CH-47 Chinook, CH-53 Stallion/Jolly Green Giant, H-60 Black Bird), they like to top off fuel tankers from KC-30 Hercules tankers. They prefer prop driven tankers that can fly slow enough for helicopters.
What is the rod on the front of a Chinook helicopter? This rod is the inflight refueling receptacle, or the probe, for a probe and drogue inflight refueling system.
It is the horizontal component which accelerates the helicopter in the direction of the tilt. So there is a force (lift) lifting the rear of the disc and lowering the front. This force is transmitted through the rigid rotor drive shaft and pushes the nose down and pulls the tail up.
The two rotors are linked by a transmission that ensures the rotors are synchronized and do not hit each other, even during an engine failure. Tandem rotor designs achieve yaw by applying opposite left and right cyclic to each rotor, effectively pulling both ends of the helicopter in opposite directions.
According to Van Heuvelen, naming helicopters after Native Americans was once an official Army regulation, which was meant to suggest an aggressive spirit and confidence. Today that regulation and stated intent no longer stands, but the tradition continues.
HMH: Marine Heavy Helicopter Squadron, the first H means helicopter; the M means Marine; the second H means heavy.
4.4. 1 The helipad touchdown point is marked by the identification lettering H so that it is easily visible from the air and can be used by the pilot as a reference mark to make his approach to the helipad.
Helo is a slang term for helicopter. Although the hel part of helicopter is pronounced with a short e (like hell), helo is sometimes pronounced with a long e and a long o: HEE-low. Helo is most often used as military slang. In general, the slang term chopper is more commonly used to refer to a helicopter.
It is good practice to crouch while exiting the helicopter if the rotors are turning. Many helicopter rotor systems can dip well below 6 feet from the ground level, which can potentially contact a person or object on the ground.
Having two coaxial sets of rotors provides symmetry of forces around the central axis for lifting the vehicle and laterally when flying in any direction. Because of the mechanical complexity, many helicopter designs use alternate configurations to avoid problems that arise when only one main rotor is used.
No. The wing and propeller are combined in the main rotor. Upside down means going down.
The primary purpose of these headsets is to reduce the noise in the cockpit (they can be very loud) in order to avoid hearing loss (yes, it is that loud) and to facilitate clearer communication with ATC. For quieter airplanes there are in-ear headsets that have more in common with earbuds than the bigger headsets.
Fog, and even too many clouds, can prevent a helicopter pilot from seeing what is around them. Though they may use instruments on board to help them navigate, the reduced visibility can still disorient a pilot enough to lead to accidents.
However, at a certain altitude, the maximum lift coefficient of the blades is reached and no further increase in lift is possible. Hence, the helicopter cannot fly beyond this altitude. This is the absolute ceiling of the helicopter.
You'll often see these aircraft flying in twos or threes. This is to provide decoys for the helicopter that the President is on. On overseas trips with heightened threat concerns, you'll even see them in groups of four or five for this purpose.
They ARE fans, and they're just for pilot comfort.
Marine One always flies in a group with identical helicopters, sometimes as many as five. One helicopter carries the President, while the others serve as decoys for would-be assassins on the ground. Upon take-off, these helicopters begin to shift in formation regularly to obscure the location of the President.
The cockpit is protected by layers of reinforced armor and bulletproof glass. According to Boeing, every part of the helicopter can survive 12.7-mm rounds, and vital engine and rotor components can withstand 23-mm fire.
Never walk from the rear of the helicopter as the tail propellers are extremely dangerous. Approach from the front of the aircraft and crouch to avoid the rotors.
Basically it is a result of static electricity created by friction as materials of dissimilar material strike against each other. In this case titanium/nickel blades moving through the air and dust. It occurs on the ground as well, but you don't usually see it as much unless the aircraft is landing or taking off.
1.) Roger That. “OK,” “Understood,” and “Yes, sir/ma'am” are all acceptable replacements for this military phrase.
13. What does Tango Mike mean? Answer: It means “thank you,” or specifically, “thanks much.” In 1955, many military organizations, including NATO and the U.S. military, adopted a phonetic alphabet to aid in correctly transmitting messages.
