4 Informative Facts about Helicopters

Insightful facts about helicopters include their description, performance, drawbacks, and history.

Although helicopters took a while to develop, they now go side by side with most fixed-wing aircrafts. And despite the fact that they have their weaknesses, their versatility still makes them a popular choice amongst civilians.


A helicopter is a type of rotorcraft where lift and propulsion are provided by one or more horizontal blades. While researches propose that more than 2 horizontal blades should be used, it has never really been tested. Through these rotors, helicopters have the ability to land and take off in isolated locations that other fixed-wing aircrafts would never be able get to. Fixed-wing aircrafts require a runway, unlike helicopters. Moreover, helicopters also have the ability to hover for a lengthy time and execute procedures during rescue operations or helicopter lessons that distinguish them from other kinds of aircraft. The horizontal rotors make a helicopter a special aircraft because they are responsible for enabling it to elevate and takeoff without the need to propel in a forward direction. Helicopters have an unique flexibility function that can not be found in other common fixed-wing aircraft. Not even the military’s own tilt-rotor aircrafts and VTOL planes can perform with the versatility that helicopters provide.


The one-of-a-kind abilities of a helicopter are made possible by the rotors that are lined up horizontally. Some rotors, especially in numerous modern designs, are capable of being articulated, enabling them to switch from vertical to horizontal propulsion. Because of this ability to articulate, these aircrafts can make fast alterations of directions whether from front to back, or side to side. Several helicopters that use one rotor normally still have an additional rotor on the rear. The rotor on the tail neutralizes the normal tendancy of the aircraft to move in the opposite direction as the rotor. This is where two rotors become advantageous in contrast to just 1 – to prevent the aircraft from spinning around in circles because each of the blades counteracts the other’s effect.


Helicopters are remarkable aircrafts, but they are not perfect. Because of their ability to land and take-off the way they do, they have characteristics that are less advantageous as opposed to a fixed-wing aircraft. They can not acquire the same velocity as fixed-wing aircrafts largely because of the configuration of their rotors that allow them to stall and perform other aerodynamic feats. Additionally, these aircrafts also don’t have very high max elevations or service ceilings, they are loud, and they have a tendency to tremble heavily.


There were helicopters developed in the past yet none of them actually had any efficient use, until 1923 when Juan de la Cierva of Spain first flew his helicopter. A few years later, the first helicopter that was dependable enough to be mass produced, the R-4 by Igor Sikorsky, was produced. And the first helicopter that had clearance to be used by civilians, the Bell 47, was unveiled in 1946.

Just like any other kind of vehicle, helicopters can be damaged, experience loss of control, or cause fatalities when they are not operated properly.
