Hydraulics are extremely useful for a number of applications, providing large amounts of power that can be used for actuating and driving systems. Hydraulics are also commonly exposed to numerous environmental conditions, often coming into contact with dust, dirt, debris, and other various substances. If these contaminants enter hydraulic cylinders and other assembly components, performance can be lost and such equipment may even begin to face damage. With the use of devices known as wiper seals, cylinders and other components can be protected from contaminants with ease.
The Dutch roll is an undesired phenomenon faced by propeller and jet engine aircraft alike, often causing an out-of-phase combination of yaw and roll movements that cause the tail structure to wag while rocking side to side. The Dutch roll motion typically results from a weaker positive directional stability as compared to the positive lateral stability, meaning that the restoring yaw motion will lag behind the restoring roll motion. This causes a slidelip to be generated in the opposite direction, reversing the process. As a phenomenon that all pilots want to avoid for efficient and smooth flight, aircraft of all types have introduced what is known as a yaw damper to their assembly.
Access doors are a standard element of countless building and assembly designs, regularly implemented for the means of permitting access to spaces behind walls, floors, or ceilings. While some may be as large as an individual, a majority of access doors are much smaller as they are typically intended for reaching smaller spaces directly behind the door. Despite access doors varying in construction depending upon their application and design, most are fitted to align with the installation surface for practical and visual reasons. Depending on one's applications and needs, there are numerous common access door types, each with unique designs and features. To help you find the best fit for your particular needs, we will provide a brief overview of the most common access door types.
Simply put, a glider is an unpowered aircraft, or an aircraft without an engine. Although many of the same design, aerodynamic, and piloting factors that apply to powered aircraft also apply to gliders, the lack of an engine inevitably changes a great deal about how gliders work. There are many different types of gliders. For the purposes of this blog, we will cover how sailplanes work.
When designing a pneumatic system, there are many options for the system’s tubing. Depending on its use, the tubing material could vary widely.
An accumulator is a device that is capable of storing energy, and its functionality is made possible through the compression of dry inert gases within a container that is open to hydraulic oils or other incompressible fluids. Present in numerous industries, hydraulic accumulators are often either bladder type or floating piston type, though other variations may exist. In this blog, we will provide a brief overview of hydraulic accumulators, allowing you to best understand how they function and how they may be used.
When utilizing navigation and guidance systems for autopilot, safety systems, and other such devices, a hardware component known as an accelerometer serves as one of the most important parts of the assembly. As an electromechanical device capable of measuring acceleration forces, static forces, dynamic forces, and speed changes can all be accurately captured for various applications. With the importance that accelerometers serve for aircraft, ships, automobiles, and various electronics, understanding their uses and functionalities is crucial for anyone regularly operating such systems.
An aircraft fairing is a structure that serves to produce a smooth outline and diminish drag on aircraft surfaces. Fairing's primary functions are as covers for gaps and spaces between parts of an aircraft to reduce both form drag and interference drag while improving appearance.
While rockets and their engines can seem immensely more powerful and complex as compared to aircraft engines, their method of operation is actually somewhat similar. As is with all reaction engines, rockets produce thrust through the ejection of materials in accordance to Newton's third law of motion. As such, rockets utilize the combustion of reactive chemicals in order to create the propulsive force needed to achieve acceleration.
As aircraft and their structures continue to be developed and improved upon, various control surfaces have come about to assist in stabilizing the aircraft during flight and allowing for pilots to adjust directional heading. On the tail-end of the fuselage, aircraft often utilize elevators and horizontal stabilizers in order to adjust the pitch, yaw, and other axes alongside providing stabilization. For more higher performance aircraft that require more maneuverability, such as high speed military fighter jets, a fully moveable surface known as a stabilator combines the functionality of the elevator and horizontal stabilizer.
