Relative wind, an important factor to consider during flight, refers to the relationship between the wing of an aircraft and the direction of airflow over said wing. In normal flight, the airflow of relative wind is in the opposite direction of the aircraft flight path. This means that if the aircraft flight path is forward, the relative wind is backwards and vise versa. Additionally, if the aircraft is ascending, the relative wind is downward.
Learn MoreThere are many layers of regulation in the aviation industry. Almost every major player, including commercial airlines, supply chain companies and aircraft manufacturers, need to abide by the FAA and other aviation authorities. This is to ensure that every aircraft as well as all the parts that make up the aircraft are 100% certified of airworthiness. The many layers and regulations are put in place so that if a faulty part or another type of error manages to fall through the inspection gates, then they can be identified by the many other gates that follow afterward.
Learn MoreProper radio communication is a basic need of anyone piloting an aircraft. To ensure the reliability of its communication systems, aircraft are fitted with sophisticated radio equipment and antenna. Radio signals typically travel in one of two frequency bands, very high frequency (VHF) or ultra high frequency (UHF). Aircraft use VHF for short range communication, transmitting radio signals from 54 MHz and 216 MHz. The range of communication of a given frequency depends on the height of the antenna relative to the ground. This means that aircraft at high altitudes have a larger VHF ranges than those at lower altitude.
Learn MoreSevere turbulence isn’t just a nuisance when you’re flying, it can also be a genuine health hazard. The Federal Aviation Administration reported 44 injuries related to turbulence in 2016, most of them suffered by flight attendants that were up and moving around the aircraft when the turbulence hit. Given that over 932 million passengers flew on domestic flights that same year, however, this number is mercifully low. One major reason why there are so few turbulence-related injuries is that pilots have gotten better at predicting when turbulence is coming, and warning passengers.
Learn MoreThe hot section of any turbofan or turboprop airplane is key in producing thrust, the seminal force used in flight. It is a collection of important engine parts such as the turbine blades, combustion chamber, stators, vane rings, compressor turbine disk, and shroud segments. As these are crucial components to the performance of the engine, hot section inspections are imperative in ensuring the reliable performance of your aircraft.
Learn MoreThe U.S. military is a highly coveted customer within the aerospace and defense supply chains as their need for components is understandably plentiful. Each and every part that the DoD uses however, must have a National Stock Number (NSN) assigned by the Defense Logistics Agency. A manufacturer can not request an NSN, instead the component must be recognized by the military, a participating NSN country, or a government contractor.
Learn MoreThe complexity of aircraft hydraulic systems depends heavily on the functions it needs to perform. In smaller planes, hydraulics is used to operate constant-speed propellers, landing gear, and aircraft wheel brakes. On larger planes, the systems tend to be more complex as they are used to operate flight control surfaces, spoilers, wing flaps, brakes, and other flight critical functionality. The principles of hydraulics are based on Pascal’s law—pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid, such that the pressure ratio remains constant.
Learn MoreBearings are some of the most common mechanical elements in any machine or system. Typically, bearings are components used between two other components that allow for rotational and/or linear movement, while reducing friction and increasing efficiency. This is based on the simple idea that things roll better than they slide.
Learn MoreAircraft flaps are a high-lift device designed to increase aircraft lift once a certain speed is reached. Flaps help the wings adapt to whatever phase of flight they may be in. The usage of flaps on wings provide these three major advantages:
Learn MoreWhether you are a pilot or just the owner of a plane the FAA allows you to change your aircraft oil, by yourself. If you’ve ever wondered how to get the process rolling and what tools you made to need to have a successful job, keep on reading.
Learn MoreIn order to discover how broadband communications, for example, can result in high data rates for mobile final users, the Heinrich Hertz’s mission was created aiming to examine and test communications technologies in space at a technical and scientific level. The satellite was scheduled to launch in 2016 with an investment of 310.5 million euro and an 11 million contract to OHB in 2011.
Learn MoreBoeing rolled out the first 787-10 Dreamliner at its South Carolina aviation plant. Thousands celebrated as President Donald Trump and Governor Henry McMaster announced the airplane’s debut. The 787-10 will be the longest model in the Dreamliner family at 224 feet, an eighteen-foot increase from the 787-9. Passenger capacity was increased an additional thirty seats and the cargo area was expanded, yet the plane is calculated to have a 95% commonality score to the 787-9. The Boeing Company achieved its goal of lengthening the plane without any major changes as a resource saving strategy, narrowing its scope for Dreamliner spare parts and training requirements.
