How Apache Helicopters Work
An Apache helicopter is a piece of heavy duty machinery. It takes military training and precision to operate this beast. However, most people do not understand the technology that goes into one of these amazing aircraft. This article is meant to explain how an Apache helicopter works in laymen’s terms.
There are two main systems that are important for understanding how Apache helicopters work: the propulsion system and the control system. Let’s start with the propulsion system.
The propulsion system is made up of two turbine engines, which are connected to a transmission box by drive shafts. The transmission box then powers the main rotor blades, or rotors for short. The rotors are responsible for providing all of the lift for the aircraft and also provide thrust when flying forward or backward. To move forward, all of the engine power needs to be transferred from the rotor blades to the transmission box, while still providing enough lift to keep the aircraft airborne. This is done by changing the pitch of the rotor blades so they are at an angle instead of being perfectly vertical. The angle causes air to “slip” past the rotor blades and creates thrust in an opposite direction. This thrust allows it to fly forward or backward with ease.
Why do we care about how Apache Helicopters work? Apache Helicopters are a perfect example of how we can apply many fundamental principles of physics to solve real-world problems. There are so many aspects of flying that require knowledge of physics, which is why engineers must have a thorough understanding of physics before designing a vehicle that will fly.
The Apache helicopter is probably the most complex machine ever built. It is truly amazing how so much power and aerodynamic technology can be put into one small vehicle. The Apache flies at speeds over 200 miles per hour with enough power to carry missiles and rockets that weigh hundreds of pounds.
The pilot controls the helicopter in the air with 2 sets of controls. The cyclic (left handle) controls the pitch and roll while the collective (right handle) changes the altitude by adding or decreasing lift.
An Apache attack helicopter is a four-bladed, twin-engine aircraft that carries one or two crew members. The Apache can fly in all weather conditions and perform missions during the day or night. It can carry eight Hellfire missiles, as well as four Stinger air-to-air missiles and 1,200 30mm rounds for its 30mm cannon.
The Apache’s main armament is its 30mm M230 chain gun. The gun is mounted on the nose of the helicopter and fires up to 625 rounds per minute of armor piercing, high explosive projectiles. The gun’s computerized fire control system actually allows the pilot to lead targets by firing in front of them to allow for lag time. The M230 also has an incredibly high first round hit probability of 80 percent even while firing on the move.
The Apache has two T700-GE-701C turboshaft engines that can produce 1,099 shaft horsepower each. The engines are made by General Electric and are also used on Army Black Hawk utility helicopters and Marine Corps Sea Stallion helicopters.
The AH-64A Apache is a tandem cockpit, twin-engine helicopter that can carry up to 16 Hellfire missiles. It is equipped with an M230 30mm automatic gun, 2.75 inch rockets and a stabilizing system for precision firing.
The AH-64D Apache Longbow is the most advanced multi-role combat helicopter for the U.S. Army and a growing number of international defense forces. Boeing delivered the first production AH-64D Apache Longbow aircraft in March 1997 and has delivered more than 600 in total to U.S. and international customers to date, including Australia, Egypt, Greece, Israel, Japan, Korea, Kuwait, Netherlands, Qatar, Saudi Arabia and Singapore.
The primary functions of the AH-64A are anti-armor warfare and air cavalry duties. The Apache’s primary mission is the destruction of high value targets with the HELLFIRE missile; a secondary mission is close combat attack of enemy armored forces using the 30mm Automatic Chain Gun (M230).
The Apache carries Hellfire missiles on four hard points located on stub wings on either side of the fuselage; it also carries a 30 mm (1.2 in) M230 Chain Gun mounted beneath the aircraft’s nose between the landing gear with 1200
Apache Helicopters: How They Fly
The Apache helicopter is one of the most successful and arguably recognizable attack helicopters in the world. It has been used in every major US conflict since 1990, and its use only continues to grow. It is a part of the Boeing family and it was initially developed as the AH-64 by McDonnell Douglas and Hughes Helicopters for the United States Army. In 1984, the Army selected McDonnell Douglas’ design and awarded them a contract for production of the initial batch of AH-64s. The Apache’s name comes from an Indian tribe of North America.
Apache helicopters are primarily armed with two 30mm M230 chain guns along with 16 Hellfire missiles in addition to a variety of other different weapons that can be loaded into its weapon bays depending on mission requirements. The M230 chain gun is capable of firing 625 rounds per minute, but it typically fires around 495 rounds per minute or at a rate of 8 to 9 rounds per second. The cannon can fire armor piercing depleted uranium shells or high explosive incendiary shells which when combined with their built-in laser rangefinder they can engage targets while moving at speeds up to 38 knots or 44mph while flying low level at altitudes as low as 90 feet above ground level.
The AH-64 Apache is a four-bladed, twin-engine attack helicopter with a tailwheel-type landing gear arrangement, and a tandem cockpit for a two-man crew. The helicopter is powered by two General Electric T700 turboshaft engines. It has a large amount of systems redundancy to improve combat survivability. Variants of the AH-64 have been developed by Boeing Defense, Space & Security; AgustaWestland, Lockheed Martin, and by the Israeli company Israel Aerospace Industries.
The U.S. Army is the primary operator of the AH-64; it has also become the primary attack helicopter of multiple nations, including Greece, Japan, Israel, the Netherlands, Singapore, and the United Arab Emirates. In 2015, Boeing Defense was awarded a contract worth $3.4 billion to remanufacture 124 AH-64D Apache helicopters into the AH-64E configuration for the U.S. Army.
The Apache is a battle-tested, twin-engine aircraft that has proven itself in combat from Panama to Afghanistan. It is one of the most feared and respected weapons on the modern battlefield. The Apache helicopter is a fierce combination of cutting-edge aviation technology and devastating weaponry.
The Apache was originally developed by Hughes Helicopters for the U.S. Army’s Advanced Attack Helicopter program in the 1970s. In 1976, when McDonnell Douglas acquired Hughes Helicopters, it continued work on the Apache project. The Army finally approved low-rate production of the Apache in 1982 and full production in 1983. In 1997, McDonnell Douglas merged with Boeing, which has since produced all of the Apaches that have been fielded by the U.S. Army and foreign militaries.
The Apache began as a project to replace the Army’s Bell AH-1 Cobra gunship helicopters in the 1970s, but has evolved into much more than a pure gunship helicopter. The original plan was to create an aircraft capable of delivering massive firepower in support of infantry forces while also having significant survivability by virtue of its speed and maneuverability. The key components giving the Apache its unique abilities are its advanced avionics systems, integrated weapon systems, heavy fuel capacity and maneuverability
