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

When flying aircraft that feature propeller blades, it is important to be aware of the forces that are enacted on such components. Often placed at the nose-end of an aircraft or on the wings, the aircraft propeller assembly experiences a high amount of centrifugal force during flight, often reaching upwards of 25 tons. As such, propeller blades may bend, flex, vibrate, and more during a normal operation. Coupled alongside environmental factors such as weathering and debris, aircraft propeller assemblies can lose their integrity over time and eventually become inoperable. To ensure that propellers provide as long of service lives as possible, operators should always conduct regular maintenance and inspections on set intervals.

Jet engines and rocket engines are both used throughout the aerospace and aviation industries for a variety of applications. Despite this, they operate in different ways and are suited to use in different situations. In this blog, we will discuss how jet and rocket engines work, as well as their advantages and disadvantages.

With an aircraft piston engine, the pressurized forces of combusted fuel are harnessed for the creation of rotational movement. This process is achieved by one or more reciprocating pistons which operate similarly to those of automobiles, and various aircraft piston engine types each provide their own unique benefits for flight. While the piston engine is a longstanding, reliable form of thrust generation for smaller and lighter aircraft, they still require regularly scheduled maintenance and inspection to ensure their longevity and optimal performance. From lubrication to inspecting each piston engine valve, there are a number of steps that one can take to keep their aircraft piston engine airworthy for flight.

In an industry as strictly regimented as aerospace, there are countless rules and regulations to go along with the many aircraft parts available. Furthermore, there are also a broad range of part conditions. The part conditions we will discuss in this blog are As Removed (AR), Serviceable (SV), Repaired (RP), and Overhaul (OH).

Most passengers embarking on a flight may not want their minds to wander to hypothetical emergency situations, but in order to ensure passenger and flight safety, pilots and everyone involved in the cabin crew must go through hours of training to prepare and plan for any such event. It is this preparedness that has saved lives and continues to ensure a safe and completed fight for passengers.
