Plane Aviation
Apart from knowing how to fly an aircraft, the most important aspect of aviation safety is keeping an aircraft well maintained, and not just in terms of its mechanics. Although most plane crashes are the result of pilot error or mechanical failure, there are smaller aspects of aviation safety that also have a bearing on flight safety, such as whether an aircraft's surface is free of accumulations that could disrupt airflow over its wingtips. Although it might sound incredible that small accumulations on an aircraft's surface could jeopardize its flight, they can. For example, numerous plane crashes have occurred because a thin layer of ice accumulated along the length of an aircraft's wing, disrupted the airflow over the wing, and produced a stall. The same thing can happen when other types of accumulations produce a change in airflow.
Maintaining the surface of an aircraft is easy compared to maintaining its mechanics. But there are still certain qualities to look for in an aircraft surface cleaner, particularly if you need an eco friendly cleaner. Traditionally, most general aviation cleaners contain chlorinated solvents, which are more than bad for the environment; they can also jeopardize workers' health due their emission of Hazardous Air Pollutants (HAPs). If you work for an aviation company, keeping workspaces free of HAPs can also be crucial to your company's reputation and finances. HAP related illnesses typically take years to develop. But when they do, a company can be hit with multiple lawsuits that devastate it finances, as well as its reputation.
A second characteristic to look for in an aircraft surface cleaner is a high flashpoint of 200 F or above. A solution's flash point is the temperature at which it ignites, which may seem unimportant in industrial cleaners used for aircraft surfaces. However, most pilots and aviation companies use an aircraft surface cleaner on more than a plane's surface; they also use it clean engine parts; a job for which a cleaner with a low flashpoint can be dangerous due to electrical engine parts remaining "energized" after the plane's motor is disengaged. This is especially the case in operations where planes have a quick turn around between landing and takeoff, and need to be serviced immediately.
A third characteristic to look for in an aircraft surface cleaner is its ability to work safely on all metals. As aforementioned, a surface cleaner is often used to clean various surfaces, making it essential to ensure that one surface won't be corroded while another is cleaned safely. Although determining whether an industrial cleaner will corrode a surface is a matter of chemistry, you don't have to be a chemist to identify a solution that cleans all metals safely. Instead, you can determine a safe cleaner by looking for the following three characteristics: aerospace NESHAPS compliant, no hazardous ingredients as defined by the EPA, and no SARA or RCRA listed ingredients.
In my research on industrial cleaner, I've researched the characteristics of the best aircraft surface cleaner.
AVIATION ENGINE for EXPERIMENTAL PLANE? whats a good cheap option to get? any type id like to build a plane?
be it for a lancair or more basic experimental im just wondering would a sports bike engine work?
The most important factor everyone is missing is that an aircraft engine, Lycoming, Rotax, Continental, etc are designed to make their max Hp at less than 3000 rpm. They are big engines with a huge bore and stroke. The prop has to turn at max around 3000rpm.
In comparison a 4 cylinder 2007 Yamaha YZF-R1 998cc (74 cid) one of the fastest bike, makes 156 hp at 12,300rpm. A 4 cylinder Lycoming o-320 is 320 cubic inches, and makes 160hp at 2800 rpms
The O-320 is more than 4 times bigger and turns 4 times slower to make the same power than a bike. 95% of the time the bike is nowhere near it's max rpm, whereas 95% of the time the O-320 is near it's max rpm. Also turning slower puts a lot less strain on the engine.
With the O-320 the prop is driven directly off the crank. With the bike engine you would need some kind of gear reduction to get the prop turning at a much slower rpm than the engines 12300 rpm adding more weight, more complications and more unreliability.
It can be done, I've seen all type of engines used, Mazda rotaries, Subaru flat 4's, Chevy LS1's, Buick V6's, but you should stick to something more conventional for your first build.
