The pyramids of ancient Egypt, barstools, gearsets in car transmissions, and the earthquake-proof San Francisco International Airport all have one unlikely thing in common: bearings. While relatively simple to understand, the difference that using a bearing makes can be massive. And the reason is simple: according to basic physics, things that roll meet less frictional resistance than things that slide. Aptly named, bearings “bear” the load by using smooth metal for the balls or rollers, and the inner and outer surfaces they roll against to minimize the contact area and allow for less friction and smoother movement.

Piston engine, or reciprocating engines, are related to the steam engine, which was first introduced in the early 17th century. In simpler terms, a steam engine utilizes heat to create stream pressure, which is then used to generate a rotating motion. After its creation, steam engines were used to drive everything ranging from mechanical equipment to railway trains. Today in aircraft piston engines, gas propulsion is used instead of steam to create pressure inside the engine. Read more >>

Vishay Intertechnology recently introduced a new high-speed silicon PIN photodiode with an added feature of enhanced light sensitivity. A photodiode is a semiconductor diode that converts light into an electrical voltage. When energy fueled photons are absorbed by the detector, a formation on charge carriers is created; this formation is then separated in the space-charge region, resulting in a photocurrent.

Bombardier has finally reached their seven-year goal in completing their state of art reclining chair, known as the Nuage passenger seat. After constant trial and error, the Aerospace company, has found a solution to not only correct posture but make the flight more worthwhile. The chair is scheduled to be placed upon the Global 7000 once it has been certified. Read more >>

EASAs certification regulations have been recently meet by Safran Helicopter Group to be able to bring their Arriel 2H Engine to life. Currently Safran has plans of having their engine to be able to be incorporated into a AC312E, a civilian helicopter, manufactured by Avicopter. This particular specification of the Arriel was chosen in the year 2015 due to its efficiency and unique characteristics created by Avic Harbin Aircraft Industry Group. The 2H engine derived from the previous model known as the 2+. With the new models enhanced technology, the 2H has the power to takeoff at a rate of 986 shp. Read more >>
