Many of the engines used in Remotely Piloted Aircraft (RPA), come directly from the remote-control (R/C) aircraft market, which turn a propeller but are not necessarily built for the greatest efficiency or reduced fuel consumption. The DoD “single fuel concept” is pushing these platforms to be able to operate with JP-8 using an Otto Cycle engine. Additionally, with increased environmental concern with fossil fuels, possible future DoD requirements could require the use of bio-derived liquid fuels. The research presented in this paper takes steps to satisfying both the efficiency and single fuel requirements. The Fuji BF-34EI engine was successfully shown to operate effectively with JP-8, Diesel, Algae-based Diesel and Camelina based Hydroprocessed Renewable Jet fuel. When generally compared over the entire engine operating map, between AVGAS and JP-8, the latter is shown to present a 10-20% lower brake specific fuel consumption (BSFC).

The modern automobile engine has enjoyed more than a century of continuous development dating back to 1878, when the German engineer, Dr. Nicholas August Otto exhibited his first four-cycle engine. The quests for positive displacement rotary piston machines have attracted the attention of several centuries and actually pre-date the invention of the reciprocat ing piston principles. A bewildering variety of possible rotary engine configurations seem to have been tried and at the same time, confused inventive minds, thereby preventing the early success of purely rotating engines. Over the period of time, engine technology, which was in paper those days staged a come back, and started entering the market. One such, new technology is the Wankel engine development. This engine has already made their impact in the aeronautical field, and its use in automobile field is being explored. These engines are available in both carburetor and Electronic Fuel Injection (EFI) version.

AIR5273A
This AIR provides descriptions of aircraft actuation system failure-detection methods. The methods are those used for ground and in-flight detection of failures in electrohydraulic actuation systems for primary flight control. The AIR concentrates on full Fly-By-Wire (FBW) flight control actuation though it includes one augmented-control system. The background to the subject is discussed in terms of the impact that factors such as the system architecture have on the detection methods chosen for the flight control system. The types of failure covered by each monitoring technique are listed and discussed in general. The way in which these techniques have evolved is illustrated with a historical review of the methods adopted for a series of aircraft, arranged approximately in design chronological order.
