A drone is a common term that is used to refer to an unmanned aircraft. In military terminology it is referred to as an unmanned aerial vehicle (UAV), or an unmanned aircraft system (UAS). It is a machine that  can be maneuvered with a remote control or fly autonomously through preprogrammed flight paths embedded in their systems. They are designed with onboard sensors and GPS navigation which allow it to fly seamlessly.  

Gearboxes can also be referred to as speed reducers, gear drives, or gearmotors. The main job of a gearbox is to increase torque, reduce or increase speed, reverse rotation, or change direction of the driveshaft. In this article, we will be talking about 6 different types of gear boxes. 

The most advanced electronic devices in the world are useless without proper connections and cabling. While wireless transmissions may be all the rage for the convenience and mobility they offer, wires and cables still offer a more stable, consistent, and reliable connection. In this blog, we’ll break down some of the most common types of electric cables, their designs, and their common uses.

Early aircraft utilized a single braking system with no backup or failsafe. The system was simplistic in design and eventually deemed unsafe, causing the regulating authorities to incorporate robust overhauls. Airlines had to address the issue of potential loss of the primary hydraulic pump, which led to the implementation of electrically driven pumps that provided an alternate supply of hydraulic pressure. However, these solutions didn’t address the loss of fluid issue. Some manufacturers began incorporating a compressed air system for emergency braking, yet, there was only a limited amount of air the tanks could hold. This led to the concept of multiple, independent hydraulic systems backed up by accumulators. This system proved to be effective as it allows for several layers of failure without losing total control of the braking system; a concept that is still used today.

An accessory drive in an aircraft is a gearbox that forms part of a gas turbine engine. It drives the engine’s accessories including the fuel pump, generators, hydraulic pumps, engine starter, etc. They can handle between 400-500 horsepower (hp). The shaft that links the turbine and compressor also powers the accessory drive. This setup requires an internal gearbox that has a radial drive shaft that powers the external gearbox.

The Boeing 747-400 is made up of 6 million parts— of those, half are fasteners. If you’ve never seen an aircraft up close and in person, you probably can’t imagine why of 6 million parts, 3 million are aviation fasteners. Well, that’s because fasteners are any piece of hardware used to mechanically join or affix two or more objects together. So, it makes sense that half of the 747’s part list is fasteners; what wouldn’t make sense is if all 3 million fasteners were of the same type.

In keeping with the Army’s broad strategic aim for the Bradley, they’ve decided to arm the Bradley Inc's Fighting Vehicles with Stinger heat-seeking missiles. This will aid with the infantry’s ability to monitor air threats and eradicate them. Presently, most Bradleys are equipped with tube-launched, optically-tracked, wire-guided (TOW) anti-tank missiles. These missiles are land weapons used to attack vehicles and bunkers. 

In the early days of aviation, there were no brake systems to slow and stop the aircraft while it was on the ground. Instead, slow speeds, soft airfield surfaces, and friction caused by the tail skid were used to reduce speed during ground operations. Fortunately, that’s no longer the case and all modern aircraft have brakes.

Earlier in June, THAT Corporation announced the availability of the 626x Programmable Preamplifiers. The 6261, 6263, and 6266 Programmable Preamplifiers are available in a 7mm X 7mm 48-pin quad flat no-leads (QFN) package. They are digitally controlled, 2-channel preamplifiers with integrated analog to digital converter (ADC) drivers. The gain, or amplification factor, for these preamplifiers is programmable from -8 dB to +34 dB. They are low-powered at 60 mW and can be powered from unipolar (+10V and +5V) or bipolar (±5V) power supplies. 

Aircraft Propeller Service, a leading Commercial Propeller Maintenance Repair Organizations has won a contract with Airbus Group, they will be providing services for 568F propeller blades on the EADS CASA C-295, which is a twin turbo-prop tactical military transport aircraft. The Airbus helicopter is manufactured by Airbus in Spain. Aircraft Propeller Service is the only MRO service with the capabilities to that are demanded by these massive helicopter propeller blades. Showcasing Aircraft Propeller Services amazing opportunity, APS CEO Dan Colbert said
