Advancements in aircraft reciprocating engines

Introduction There is a misconception that because modern aircraft engines built by Lycoming, Continental and other companies have similar look to engines used in general aviation aircrafts of the 1970s, there have been no technological advancements in this field. Even though new engines haven’t changed much by outward appearances, aircraft reciprocating engine technologies have advanced dramatically in past two decades. The overall build quality of engine has greatly improved. Advancements in machining technologies and automatic manufacturing processes made it possible for aircraft engine makers to enhance machine’s durability. Many components of piston engines have been significantly improved, ...

Government agencies use contracting to execute complex projects that require technical expertise. Contractors have to go through an appraisal process that determines their suitability for the job. After appraisal, the most suitable applicant wins the contract. However, the contracting process can be subject to formal complaints.
