Crankshaft Aircraft

Crankshaft Aircraft - As viewed from the front, the curved section to the left holds the crankshaft which turns the propellers to produce thrust. The curved section is open so that you can see inside. In operation, a sheet steel

plate was attached to the top to completely enclose the cylinder bays. There are four bays, separated by ribs, which hold the individual pistons and cylinders. The pistons are connected to the crankshaft by piston rods which

move in the bays. The crankshaft turns on bearings which are located on the ribs of the crankcase. This animation, viewed from the top of the engine, shows the installation of the crankshaft: The FAA is requesting information from operators of aircraft with some modified Continental O-470 engines after receiving a report of a power loss and forced landing incident traced to a fractured crankshaft in a converted engine.

and Accessibility Certification Your crankshaft is machined according to our certified process specifications to restore critical characteristics. Nitriding follows under our round-the-clock supervision, using the system we developed specifically for aircraft crankshafts. The journals are polished to the correct microfinish, the flange is plated and new hardware is installed.

Finally, our inspectors scrutinize the part before we return it to you. Our attention to detail in every repair is the foundation of our unsurpassed reputation. AOPA believes the ACS process is an effective way for the FAA to interact with the general aviation community on matters of flight safety before taking potentially unnecessary regulatory action, and we encourage operators to provide the information sought.

The resolution of airworthiness concerns addressed by evaluating data collected through this process could range from no further action being taken to the issuance of an airworthiness directive. The Airmelt crankshaft, which was ground down and inspected for reuse, was of a type "not designed to be used on the bigger bore engines," raising concern that Airmelt crankshafts "are being improperly used in these converted O-470 engine models,"

and prompting the FAA to act "to better understand the overall impact on the flying public," the ACS says. For the forty years following the first flight of the Wright brothers, airplanes used internal combustion engines

their turn propeller generate it thrust. Today, most general aviation or private airplanes are still powered by propellers and internal combustion engines, much like yours automobile engine. We will discuss the fundamentals of the internal combustion engine using the

Wright brothers' 1903 engine, shown in the figure, as an example. The brothers' design is very simple by today's standards, so it is a good one engine for students to study and learn the fundamentals of engines

and their operation. On this page we present a computer drawing of the crankcase of the Wright brothers' 1903 aircraft engine. 2) If the answer to question one was 'Yes,' have you also installed STC SE10233SC to install a Belt-Driven Vortech V-1S supercharger assembly on the same Continental engine (either before or after STC SE4985NM was installed)?

Or any other engine-related STC's in addition to STC SE4985NM? The crankcase is the "body" that holds all of the others engine parts together. It's the largest part of the engine, but it must be designed for it

be both strong and light. To keep the weight low, the brothers used aluminum to make the crankcase. The crankcase was cast at a foundry in Dayton. In this process, a mold of the crankcase is made (using sand or other

materials), and hot, liquid aluminum is poured into the mold and allowed to cool into a solid, shaped piece. You can see that the piece was fairly intricate, with a number of holes and webs. Four legs were cast into the crankcase on the corners to attach the engine to

the lower wing of the aircraft. Looking at the figure in a little more detail, there are two main parts to it crankcase, a box-like structure to the right and a curved structure to the left

as viewed from the front of the engine. 3) If you have an engine with either STC SE4985NM, SE10233SC or both installed, please confirm whether your crankshaft was manufactured using the Airmelt process or the Vacuum Arc Remelt (VAR) forging process (please refer to CSB96-8 for guidance on how to

identify your type of crankshaft). If you do not know which process was used for your crankshaft and are unable to determine it, please respond to this question with 'Unknown.'" Aircraft Engine and Accessory Company, Inc.
