Question: Aero Engine Controls produces any of several types of control systems for what kind of engines?
Context: As of June 30, 2014 OSyS has merged with Aero Engine Controls (AEC), another subsidiary of Rolls-Royce, and changed its name to Controls and Data Services. The Mikulin AM-34 (M-34) was a Soviet mass-produced, liquid-cooled, aircraft engine.  Before the war, the Russian aero engine industry was mainly engaged in producing engines of foreign design, notably Wright, Bristol, Hispano-Suiza, and Gnome-Rhône.  Several engines of so-called original design have been developed, although these were probably largely based on foreign models.  The M-34 was thought to have been originally designed in Italy by Fiat for the Russians; its design closely follows Italian in-line aero engine practice.  Its initial development was troubled, but it eventually became one of the most successful Soviet aircraft engines of the 1930s.  It was utilized on the Beriev MBR-2, Tupolev TB-3, Tupolev TB-4, Tupolev ANT-20, Petlyakov Pe-8, Kalinin K-7, Polikarpov I-17, and Bolkhovitinov DB-A aircraft as well as the G-5 and various prototype motor torpedo boats.  A version of the maritime model was adapted for use in several prototype heavy tanks in 1939, although none were placed into production. Fuel control unit is the generic term given to any of several types of control systems for gas turbine engines. Aero Engine Controls is the former name of Rolls-Royce Controls and Data Services.  The company produces engine control software, electronic engine controls (EEC), fuel metering units (FMU), fuel pumps and engine actuators for a large number of common commercial and military aircraft.  Together these parts comprise the control system for a jet engine, responsible for delivering the correct amount of fuel and maintaining engine safety. The company provides safety critical controls and asset intelligence solutions for industrial power, marine, civil and military aerospace.

The Lawrance L-3 and L-4 were early aircraft piston engines with three radial cylinders, designed and built by the Lawrance Aero Engine Company in the early 1920s.  The L-3 / L-4 series was marketed by the Wright Aeronautical Corporation as the Wright Gale after the acquisition of the Lawrance Aero Engine Company. In our modern society, computerized or digital control systems have been used to reliably automate many of the industrial operations that we take for granted, from the power plant to the automobiles we drive.  However, the complexity of these systems and how the designers integrate them, the roles and responsibilities of the humans that interact with the systems, and the cyber security of these highly networked systems has led to a new paradigm in research philosophy for next generation control systems.  Resilient Control Systems consider all of these elements and those disciplines that contribute to a more effective design, such as cognitive psychology, computer science, and control engineering to develop interdisciplinary solutions.  These solutions consider such things such as how to tailor the control system operating displays to best enable the user to make an accurate and reproducible response, how to design in cyber security protections such that the system defends itself from attack by changing its behaviors, and how to better integrate widely distributed computer control systems to prevent cascading failures that result in disruptions to critical industrial operations.  In the context of cyber-physical systems, resilient control systems are an aspect that focuses on the unique interdependencies of a control system, as compared to information technology computer systems and networks, due to its importance in operating our critical industrial operations. Honda Aero, Inc. (HAI), a wholly owned subsidiary of Honda Motor Co., Ltd., is headquartered in Burlington, North Carolina near the Burlington - Alamance Regional Airport.  The Burlington facility will serve as the primary production location for engines developed and marketed by GE Honda Aero Engines, LLC (a joint venture between Honda Aero and GE), beginning with the GE Honda HF120 turbofan engine.  Development of the facility represents a $27 million capital expenditure by Honda, bringing the company's total North American capital investment to more than $9 billion.  Production began with the GE Honda Aero Engine HF120 on March 17, 2015. Aircraft engine controls provide a means for the pilot to control and monitor the operation of the aircraft's powerplant.  This article describes controls used with a basic internal-combustion engine driving a propeller.  Some optional or more advanced configurations are described at the end of the article.  Jet turbine engines use different operating principles and have their own sets of controls and sensors. Woodward, Inc. is the world's oldest and largest independent designer, manufacturer, and service provider of control systems and control system components (e.g. fuel pumps, engine controls, actuators, air valves, fuel nozzles, and electronics) for aircraft engines, industrial engines and turbines, power generation and mobile industrial equipment.
