That pointy thing on the front of some helicopters is usually either a Wire Strike Protection System (WSPS) (wire cutters) to protect against power lines or a long Refueling Probe for mid-air refueling, depending on the helicopter's mission and type. The WSPS looks like angled blades designed to cut wires that might snag the rotor or landing gear, while the refueling probe is a retractable arm used to connect with tanker aircraft.
They sometimes feature advanced systems that most people may not be able to explain. One such system is the unusual pole that typically protrudes from the front of these aircraft. The pole in question is a refueling probe that enables the helicopter to top off its fuel from a tanker without landing.
The wire strike protection system (WSPS) is a mechanical wire cutter designed to mitigate the risk of wire strikes while flying helicopters at low level. A Bell 206 shows cutters above and below cockpit section of WSPS.
The term Jesus nut is a colloquial, and somewhat tongue-in-cheek term that is used to refer to the main bolt that anchors the rotor blades to helicopter rotor heads. It is an important bolt since it has only one point of failure which if it fails could loose rotor blades and hence have a crash helicopter.
Also abbreviated to 'the cyclic' or the 'stick', this is the most fundamental aspect of the flight system. It is also one of the most instantly recognisable elements in a helicopter flight control system and is quite literally a 'stick' either in front of the pilot or positioned between the pilot and co-pilot.
Main or Tail Rotor Damage: A strike to the main or tail rotor can result in holes or broken blades. Loss of Engine Power: Bird strikes can shut down engines mid-flight. Obstruction of Vision: A bird strike can obstruct a pilot's vision, impair their control of the aircraft, and endanger the lives of everyone on board.
Jesus nut is a slang term for the main rotor retaining nut or mast nut, which holds the main rotor to the mast of some helicopters. The related slang term Jesus pin refers to the lock pin used to secure the retaining nut.
WHAT IS THE HARDEST MANEUVER TO LEARN IN HELICOPTERS?
What is that long rod that comes out the front of some Chinook helicopters? It is indeed the aerial refueling probe.
More advanced helicopters use heading-hold gyros, which actively hold the tail in a certain direction even in wind or other forces. This gives much more stability and control. Modern flybarless systems integrate multiple gyros (for all axes) and replace the mechanical flybar.
Description. A bird strike is strictly defined as a collision between a bird and an aircraft which is in flight or on a take off or landing roll. The term is often expanded to cover other wildlife strikes - with bats or ground animals. Bird Strike is common and can be a significant threat to aircraft safety.
The pitot tube is an aerodynamic device that's essential for measuring the aircraft's airspeed. It extends about 21.5 inches in front of the cockpit, and its design allows it to capture the air pressure generated by the helicopter's forward motion.
The H-47 Chinook is the heavy-lift helicopter of choice for the U.S. Army and 20 international operators. This tandem rotor workhorse excels in cargo and troop transport, search and rescue, casualty evacuation, special operations and disaster relief.
The helicopter will exhibit a tendency to make a sudden, uncommanded yaw that will develop into a high turn rate if not corrected. Recovery from this condition may be difficult if no airspeed is available, and will require entry into an autorotation (thus removing the torque of the engine and transmission).
The Jesus nut is the main rotor holding nut, or pin, that holds the main rotor to the mast of some helicopters, according to science and tech website Technology.org.
The initial letters of the inscription in Latin, “Iesus Nazarenus Rex Iudaeorum,” which means “Jesus of Nazareth, the King of the Jews.” When Jesus was crucified, Pilate had this inscription placed on the cross. It was written in Hebrew, Latin, and Greek (Jn 19:19-20).
Did you ever wonder what the long "thing" on the front of our helicopters is? ... It's a refueling probe used to take fuel from an airplane! Here's a look at our HH-60 Pave Hawk Helicopter refueling from our HC-130J Combat King II Search and Rescue Aircraft!
Yes, you can fly helicopters safely in rainy conditions with the right training, equipment, and precautions. Flying in light to medium rain is usually fine, but you should avoid flying in heavy rain. Visibility, performance, and cloud ceilings are the primary limiting factors.
Understanding a Helicopter Accident
According to the National Transportation Safety Board (NTSB), helicopters crash at a higher rate than airplanes. The crash rate for general aircraft is 7.28 crashes per 100,000 hours of flight time. For helicopters, that number is 9.84 per 100,000 hours.
Pilot error is the number one cause of aviation accidents. Piloting an aircraft requires lengthy training, a knowledge of the mechanical components of an aircraft, and hand-eye coordination skills to effectively and safely maneuver an aircraft. Pilots also have to think ahead.
Helicopter Crew and Pilot Helmet Uses:
An protective helmet shell can reduce the likelihood of concussions, loss of consciousness, and other head trauma.
Flying a helicopter takes skill, practice, and dedication. Pilots must master complex controls and understand unique aerodynamics. With proper training and commitment, many aspiring aviators can learn to fly these versatile aircraft.
Examining the Power Lines: Examining the extensive system of overhead power lines is the primary responsibility of these helicopters. By flying low, the helicopter's skilled observers can see the cables, poles, and towers up close.
