In the realm of mechanics, a transmission is simply a machine placed within a power transmission system which is capable of managing the application of power. When placed within a vehicle, the transmission system is tasked with transforming the output of an internal combustion engine into a force that can be harnessed by wheels, rotors, and other such assemblies. In regard to helicopters in particular, the transmission system is implemented for the means of transferring power from the engine to the main rotor, trail rotor, clutch, and freewheeling unit. In this blog, we will discuss the primary components of a typical helicopter transmission system, allowing you to better understand how each assembly section and its related components work together to help the helicopter achieve and maintain flight.

Lighting strikes are extremely common, often occurring around 100 times every second across the globe. Despite the possible worries of aircraft passengers, lightning poses minimal risk to the individuals aboard the vessel. Oftentimes, a strike may even occur during flight without any passengers noticing, and a typical aircraft will be struck multiple times a year on average. While lightning generally poses little risk to an aircraft, it is still important that ample protection is implemented to ensure that fuel tanks, sensitive electronics, and other aircraft parts are all kept isolated from strikes. To reduce the threat of lightning strikes, engineers utilize a number of common protective solutions and techniques.

Gas turbine engines and reciprocating engines are technological marvels, allowing small and large aircraft to efficiently travel across the globe. Unlike the engine of an automobile or an early aircraft, the starting process for a modern aircraft engine is much more complex and may require multiple equipment pieces to be carried out. As engine assemblies are paramount to the capability of flight, it can be extremely beneficial to understand how the engine starting process works as well as what systems are involved in order to ensure proper functionality.

Propellers serve numerous aircraft for their propulsion generation, and keeping them well maintained is crucial for long service lives and optimal performance. When propellers require various forms of maintenance or replacement, it is important that one knows the correct procedures for both removal and installation. While one should always refer to specific manufacturer specifications and instructions for how to properly remove and install propellers, there are some general procedures that most assemblies will follow.

For an internal combustion engine to provide an aircraft with sufficient propulsion generation, both fuel and air need to be efficiently mixed and combusted throughout the duration of the flight. While there are multiple methods of producing and igniting fuel and air mixtures, many aircraft will utilize equipment known as carburetors. With a carburetor assembly, intake air can be measured and properly mixed with fuel to produce an optimal ratio for combustion. Typically, many carburetors will be a float-type, meaning that they utilize a carburetor float to measure and regulate fuel flow.

Heating, ventilation, and air conditioning (HVAC) is a technology concerned with the thermal comfort and air quality of an indoor environment. By heating or cooling air with various systems and components, the temperature of a building can be controlled with ease. To route such treated air and ensure its proper distribution throughout a building, a number of air ducts may be implemented. Depending on the need of the system and recommendations by HVAC professionals, a number of air duct types may be chosen from.
