Source: futureflight

The helicopter is unarguably the most versatile flying machine ever created by humans. Helicopters have advanced to the point where they are essential in modern civilization. They have changed the aviation industry and expanded the range of possible uses for aircraft.

One of the key advantages of helicopters lies in their unique capabilities. They can hover in one place, take off and land in small and restricted areas, lift heavy loads, and operate at low altitudes. These characteristics have made helicopters highly versatile, allowing them to be modified and customized to serve specific needs.

In today’s world, helicopters are a common sight in many parts of the globe. They are used for various purposes, including traffic monitoring, community policing, and cargo transportation. The versatility of helicopters has made them an integral part of our society’s infrastructure, fulfilling vital roles and providing valuable services in various sectors.

25 Types of Helicopters

Let’s have a detailed look at the 25 most common types of helicopters:

1. Compound Helicopter:

A compound helicopter is a type of helicopter that employs an alternative method of propulsion to achieve forward motion. Unlike traditional helicopters that tilt their main rotor for forward movement, compound helicopters utilize an additional propulsion system to achieve higher speeds.

This can include a tail-mounted propeller or a turbojet engine. By utilizing this secondary propulsion method during cruising flight, the compound helicopter can reduce the workload on the main rotor, enabling faster speeds and improved fuel efficiency, thereby increasing its range.

One notable attribute of compound helicopters is the inclusion of short, stubby, fixed wings on the helicopter’s fuselage. These wings serve to generate extra lift by harnessing the forward motion of the aircraft.

2. Single Main Rotor Helicopters:

Single-rotor helicopters are the most common type of helicopters in use today. They feature a primary rotor positioned directly above the cockpit, which enables vertical lift and, when tilted, facilitates forward movement. The main rotor can consist of anywhere between 2 to 7 blades. For example, the Sikorsky Sea Stallion employs 7 blades.

Additionally, these helicopters possess a smaller tail rotor responsible for directional control and stability. While traditionally using blades, advancements in technology, such as the MD Helicopters’ MD520N’s anti-torque system, allow for tail rotor options with varying characteristics.

Single-rotor helicopters are renowned for their reliability, maneuverability, and ability to hover in place. They are well-suited for diverse tasks such as aerial firefighting, search and rescue operations, and helicopter tours. Examples of single-rotor helicopters include Eurocopter EC225 Super Puma.

3. Tandem Rotor Helicopters:

Tandem rotor helicopters are a type of helicopter that utilizes a specific configuration involving two main rotors and no tail rotor for anti-torque control. In this design, one rotor is positioned at the front of the helicopter while the second rotor is placed at the rear, slightly higher than the front rotor.

These two rotors spin in opposite directions, effectively counteracting each other’s rotational torque and eliminating the necessity for a tail rotor. The height disparity between the rotors ensures that they do not collide during operation, even when subjected to significant flexing under heavy loads.

Tandem rotor helicopters are well-suited for military operations and heavy lifting due to their typically larger size and increased power compared to single-rotor helicopters. Examples of tandem-rotor helicopters include the Boeing CH-47 Chinook and the Bristol Belvedere.

4. Coaxial Helicopters:

Coaxial helicopters represent another type of dual main rotor helicopter. In these helicopters, the rotors are positioned on the same axis, with one rotor located directly above the other. The rotors spin in opposite directions, effectively counterbalancing the torque produced by each other.

As a result, a separate tail rotor is not necessary for these aircraft. Moreover, the absence of a tail rotor enables coaxial helicopters to have a more compact design, allowing them to access small spaces compared to conventional helicopters.

This characteristic makes them highly sought after for marine applications, where landing on small ship decks or other maritime structures such as oil rigs is required. Examples of coaxial helicopters include the Kamov Ka-27 from Russia and the Sikorsky S-97 Raider from the USA.

5. Tiltrotor Helicopters:

Tiltrotor helicopters represent a unique hybrid between helicopters and fixed-wing aircraft. These helicopters feature two rotors, each mounted at the end of a wing. Each wing is shaped like a wong of conventional fixed-wing aircraft.

The rotors and engines are situated within nacelles at the wing tips, allowing them to rotate between a vertical position, resembling a traditional helicopter, and a horizontal position, similar to propellers on a fixed-wing aircraft. In the horizontal position, the rotors provide vertical lift akin to a standard helicopter rotor.

However, when swiveled to the vertical position, the rotors function as propellers, generating forward or horizontal thrust, while the wing shape provides the lift component. A prime example of a tiltrotor helicopter is the Bell Boeing V-22 Osprey.

6. Intermeshing Rotor Helicopters:

Intermeshing rotor helicopters, also referred to as synchropters, are equipped with two main rotors that rotate in opposite directions and overlap with each other. These rotors are mounted at a slight angle, enabling the blades to interlock without collision.

However, this arrangement results in neither rotor providing optimal vertical lift, leading to decreased overall efficiency of the aircraft. While most intermeshing rotor helicopters employ two blades per rotor, some variations, such as the Kellett XR-10 from the USA, feature three blades per rotor.

Despite the efficiency trade-off, intermeshing rotor helicopters excel in operating within extremely confined spaces. They find frequent use in military operations, search and rescue missions, and transportation across rugged terrains.

7. Electric Helicopters:

Electric helicopters are a category of helicopters that utilize electric propulsion instead of conventional fuel-powered engines. These helicopters have electric motors and rely on batteries to generate power. Opting for electric propulsion presents several benefits, including lower operational expenses, reduced environmental footprint, and decreased noise emissions.

Notable examples of electric helicopters include the Airbus City Airbus, designed for urban air mobility, and the Volocopter, utilized for short-distance aerial transportation. Electric helicopters are finding emerging applications in areas such as air taxi services, package delivery, and aerial surveys.

8. Air Ambulance Helicopter:

Troop carrier helicopters are helicopters specifically designed for the purpose of transporting military personnel and equipment. They serve as valuable assets for facilitating rapid deployment and supporting diverse combat operations.

Troop carrier helicopters emerged as a vital means to swiftly transport troops to battle zones and execute agile attacks. This mode of troop delivery, commonly referred to as an air assault, enables the direct deployment of troops to the frontlines without the necessity of landing at an airstrip and subsequently relying on ground-based vehicles to transport them to the battleground.

10. Attack Helicopter:

Attack helicopters are specifically built to engage enemy targets during combat. They are equipped with advanced weapon systems and can provide close air support to ground forces.

While early prototypes of attack helicopters could carry a small number of troops, modern versions typically lack the space for passenger or troop transportation. Instead, they are typically operated by a two-person crew positioned in a tandem configuration, with one seated behind the other.

Attack helicopters have demonstrated their effectiveness not only against ground targets but also against other fixed-wing military aircraft. This is due to their ability to take advantage of radar clutter provided by natural ground features such as trees and topography. This enables them to conceal their presence.
