Types and Construction of Marine Propellers

Marine propellers operate, essentially, the same way that aircraft propellers do: the propellers generate forward thrust by pushing the fluid back, and the resulting force moves the object forward. This is due to Newton’s third law of motion— for every action, there is an equal and opposite reaction. The propellers are connected to a rotary shaft that is powered by an engine. But marine propellers come in many different specs, all classified and sorted by the number of attached blades and the blade pitch.

Understanding Capacitors: Ceramic, Electrolytic, and Supercapacitors

“It’s all part of the genie gig—phenomenal cosmic power... itty bitty living space.” In terms of this itty-bitty electrical component, the Genie in Disney’s Aladdin had it right. Capacitors provide a large amount of power in a compact vessel and are used in a wide range of electronics. They are a passive electrical mechanism charged by a current, with the ability to store energy within an electric field. This capability can be utilized to power a camera flash, remote signal, or even switch AC current to DC smoothly.

6 Interesting Facts You Never Knew About Aerospace Engineering

Aerospace engineering is defined as a field associated with the design, development, and manufacturing of aircraft and spacecraft. There are two overlapping branches in this field: aeronautical and astronautical engineering. Aeronautical engineering refers to aircraft that operate within Earth’s atmosphere, while astronautical engineering refers to spacecraft that operate beyond Earth’s atmosphere.  In order to familiarize yourself with aerospace engineering, here are 6 fun facts you probably didn’t know about aerospace engineering.          

5 De-icing Equipment to Consider for Your Aircraft

One of the most dangerous things that can happen to your aircraft is icing. The frozen water and sleet that form on the exterior of your aircraft can be disastrous, so it’s crucial to use de-icing equipment and know which equipment you should use. Pneumatic de-ice boots, weeping wings, bleed air heated surfaces, electrically heated surfaces, and electro-mechanical expulsion is all helpful tools in de-icing your aircraft.

How We De-Ice Aircraft Before Takeoff

We don’t really think about it, but it’s amazing that we fly year-round. We fly in the heat of summer and in the cold of winter. And we do so safely and without worry. Most of the time at least. But if stop to think about it a bit, we’d realize that flying in the winter, when it’s so cold that water freezes to form snow and ice in seconds, is dangerous because just a bit of ice freezing on the wrong part of an engine could be disastrous.

Use of Engine Baffles and Cowls in Aircraft

Engine baffles have a powerful responsibility in securing that the engine is accurately cooled. Engine baffles and cowls are created to produce an air seal linking the top and bottom of the engine. The air seal’s responsibility is to ensure that the cooling air is precisely conducted through the engine, oil cooler, and engine section to undertake the correct cooling of the engine.

Global 7000 Business Jet Receives a Delightful Touch

The European Business Aviation Convention & Exhibition will be hosted in Geneva, Switzerland from May 29 to 31. Bombardier, the world’s leading manufacturer of both planes and trains, collaborated with Lufthansa Technik and developed Touch CMS solely for the forthcoming Global 7000 aircraft.

3 Steps to Help Keep your Propeller Blades in Top Condition

• Wooden propeller blades:

All you need to be able to clean wooden blades is some mild detergent and warm water. Wooden blades also use brushes or cloth to clean the dirt and grime off the propellers.  

Rolls Royce Begins Icing Tests on its Engine Parts

Rolls-Royce has introduced a new low-emission combustion system for their future engines. The first test was successfully completed in Canada at -20*c, just a month after its first test run. The new demonstrator engine features the Advance3 and the Rolls-Royce UltraFan which also play very important roles in Rolls-Royce goal of the intelligent engine. The intelligent engine created by Rolls-Royce is envisioned to have revolutionary technological abilities and digital capabilities. This engine is monitored by ALECsys (Advanced Low Emissions Combustion System), which monitors weather and thrust requirements for the pilots. It does this by changing the mixture of fuel and air being sent to various parts of the aircraft depending on different factors.

HeliRussia 2018: Spotlight On Engine Building For Helicopters

One of the most experimental and inventive areas of the helicopter industry is aircraft engine building. It is not only complex to the helicopter industry but the aerospace industry in general. R&D, a new aircraft engines tech, is able to act as a stimulus for the progress of technologies progress. Inattention to this, the 2018 HeliRussia expo will focus and put the spotlight on helicopter engines.

Leading German Engine Firm Adds to Sikorsky Heavy-Lift Bid Team

Sikorsky Aircraft’s newest partner, MTU Aero Engines, is looking to pursue the German Air Force’s heavy-lift competition. Germany’s Air Force confirmed it holds an eighteen percent work share in the CH-53K engine program.

Last BUT Very Not Least, As Bombardier Completes Its Global 7000 Flight Test Program

A new chapter for the Bombardier team has finished as they are able to complete their Global 7000 program deeming their Global 7000 FTV aircrafts as airworthy. The entire program was wrapped up as their anchor aircraft, known as the “The Masterpiece” completes its prerequisites for certification. Alongside the continuous tests it managed to also abide by “full airframe fatigue test milestone” regulations that is required for it enter in to service.
