Aircraft Maintenance Manuals (AMMs) serve as the cornerstone for the proper maintenance and repair of aircraft across the aviation industry. These comprehensive documents provide detailed instructions, procedures, and guidelines for maintaining, inspecting, and servicing various components and systems of an aircraft. From routine checks to complex repairs, AMMs are indispensable resources for aircraft technicians, engineers, and operators worldwide.
Aircraft polishing is a critical aspect of aviation maintenance that often goes underappreciated. While pilots and passengers rely on the advanced technology and expertise of aviation professionals for safe flights, the role of aircraft polishing cannot be overstated in ensuring a secure and efficient journey. In this blog, we will discuss the importance of aircraft polishing in enhancing flight safety, focusing on various components such as flight fixtures, joints and screws, landing gear, and the engine cowling.
In general, the rudder is responsible for shifting the shape of the vertical stabilizer’s airfoil, increasing drag and allowing the aircraft to move accordingly. For further context, yaw motion is defined as side to side movement of the aircraft nose and it is usually caused by the deflection of the rudder. The change in side force generated by deflecting the rudder creates a torque about the center of gravity, causing the airplane to rotate.
As powered aviation became increasingly popular in the 1920s and 1930s, engineers and manufacturers began to seek ways in which drag could be reduced for the benefit of increased performance and efficiency. Through various experimentation, things like the single-wing design and the use of lightweight materials became much more popular. Around this time was also when wind tunnel testing became widespread, making the experimentation process more optimal. This all eventually led to the implementation of nacelle structures on aircraft for drag reduction, and they were heavily used during World War II for fighter aircraft like the P-38 that featured three separate nacelles.
Hydraulic systems are a staple of modern aircraft, such technology taking advantage of the properties of compressed fluids situated in enclosed spaces to create harnessable force. With hydraulic systems, aircraft are able to effectively control flight surfaces, deploy and retract landing gear, and much more. In this blog, we will provide a brief and basic overview of the aircraft hydraulic system, allowing you to have a better understanding of its design, use, and capabilities.
Aircraft are generally serviced and maintained by Ground Service Equipment (GSE) which consists of service carts like tow trucks as well as repair or replacement components. Aerospace GSE supports a wide range of intricate systems by providing hydraulic test stands, compressors, nitrogen, cooling air and various components such as hydraulic quick couplings. Due to the services GSE provides, hydraulic aircraft GSE must be properly maintained according to the OEM operations manual, allowing the service team to carry out trouble-free service and prevent costly problems.
For applications that require moving parts that rely on the rotational motion of shafts, a roller bearing should be employed to mitigate movement. Roller bearings allow for additional support and reduced friction within such mechanisms. As they are common components in many systems across various industry verticals, roller bearings are available in a vast array of designs to fit different applications. When you are looking for certain aviation applications, such as aircraft fuel pumps, the best option is a tapered roller bearing, those of which contain an inner ring, outer ring, and a number of tapered rollers. Shaped like a cone, these mechanisms are able to withstand heavy axial and radial loads. As such, they are quite versatile, so this blog will explore the workings of tapered roller bearings for your better knowledge for various applications.
