Helicopters are a very unique and useful form of aircraft, capable of carrying out many operations that conventional fixed-wing aircraft are unable to do as a result of their VTOL and hovering capabilities. While lift and movement is made possible through rotor assemblies situated on the body of the helicopter, these rotor blades would not spin if not for the energy supplied to them by the engine. While helicopters may take advantage of various engine types depending on their design and intended application, the primary choice will often come down to whether a piston or gas turbine engine is better. In this blog, we will discuss both engine types, allowing you to better understand how they benefit helicopters.

The blades on drones that spin rapidly to create the airflow necessary to help drones fly are called drone propellers. They are a basic part of the assembly that is replaceable and is essentially a propulsion system that is responsible for lifting drones up in the air. Drone propellers do not just help drones fly up and come back down but also, depending upon the type of propeller, aid in moving the drone in other directions as well. Different drone propellers play varying roles based on their capabilities like making the drone hover or move forward and back.

While many people have seen airplanes flying in the dark, some may wonder what type of headlights these airplanes use to see well from a great distance. To the surprise of many, aircraft do not actually use headlights as would be seen on a standard automobile. Instead, they use landing lights to establish visuals while taking off and landing in place of headlights. These landing lights are powerful enough to help you see the airplane from almost 100 miles away and are ten times brighter than any regular headlights on a vehicle. 

All aircraft necessitate routine maintenance and regular checks to ensure that they are working optimally. During these checks, parts are examined for flaws, aircraft surfaces are assessed for wear, and components may even be replaced or repaired. However, not all parts can be reused and instead must be replaced. For instance, the brake lining and disc brakes must be replaced as they can deteriorate over time. 

When aircraft land, they must dump fuel before reaching the ground. While someone unfamiliar with this process may think this is wasteful, it is actually very efficient. Dumping fuel is a means of lowering the weight of the plane so that it endures less stress as it lands. 

Aircraft have radically changed the way that we travel and interact with one another on a global scale, allowing individuals to traverse the world in a matter of hours. While we often take aircraft technology for granted due to how it has heavily permeated modern society, it is a field that has only been around for a short amount of time with the first powered flight being conducted in 1903. To help you better understand how modern flight is made possible, we will be discussing the physics behind aircraft in operation.

A shaft collar is a simplistic component that may be found in various types of power transmission assemblies and other applications. While coming in a number of variations, most shaft collars consist of a metal or plastic ring that has one or more screws. The screws on the shaft collar are capable of moving in and out of the side of the shaft when tightened and loosened, and they are used to secure the machine component around a shaft. When a shaft collar is tightened onto an assembly, they can operate as a mechanical stop that either holds parts in place or acts as a load bearing face. Due to their ease of installation and capabilities, shaft collars can be found in numerous assemblies and settings.

Inertia in Physics
The Laws of Physics play a significant role in Aerodynamics. Due to improper calculations or a lack of calculations as a whole, subtle or even catastrophic problems can occur during flight. One such problem is what we call inertia coupling. Inertia coupling can also be referred to as inertial roll coupling. To understand this phenomenon, we must first define inertia itself. Inertia is a property of physics in which any object will tend to stay in its current state of stability or stable motion. The object itself can be completely still or moving in a straight line, but the idea is that it will resist any type of motion beyond its current state unless an external force is involved and causes change. Inertia coupling is a phenomenon that can occur during high speed flight. Before methods were understood to counter the dangerous effects of inertial roll coupling, some aircraft and their pilots were lost. When the inertia of the fuselage, which is the main part of an aircraft where passengers and cargo are situated, exceeds the abilities of aerodynamic forces produced by various parts of the plane to keep the aircraft under control, the aircraft becomes unstable.

Spacer plates, or spacers, are used to provide distance between two or more components being fastened. Spacers are often a varying length of tubing which not only increase the distance between two parts, but also serve as a tube where a fastener is inserted. Most spacers are designed with a clearance hole through which a bolt is inserted, meaning that the spacer does not directly engage with the threads of the bolt.

While technological advancements to vehicles can always result in higher performance capabilities, easier handling, and other such improvements, one of the most important results of innovation is increased safety. For aviation in particular, the advent of the aircraft Automatic Brake System (ABS) has allowed for more efficient and safe braking procedures by providing proper engagement times and automatic deployment. While simple in operation, the ABS ensures that pilots can safely touchdown on runways during a variety of weather conditions and that braking always deploys with optimal timing for efficient stopping power without having to use the brake pedals.
