In recent years there has been increasing interest in quantifying the emissions from aircraft in order to generate inventories of emissions for climate models, technology and scenario studies, and inventories of emissions for airline fleets typically presented in environmental reports. The preferred method for calculating aircraft engine emissions of NOx, HC, and CO is the proprietary “P3T3” method. This method relies on proprietary airplane and engine performance models along with proprietary engine emissions characterizations. In response and in order to provide a transparent method for calculating aircraft engine emissions non proprietary fuel flow based methods 1,2,3 have been developed. This paper presents derivation, updates, and clarifications of the fuel flow method methodology known as “Fuel Flow Method 2”.

In the research of lightweighting solutions, the use of CFRP has dramatically increased during the last two decades to represent today about 50 percent of the materials used in the recent commercial aircrafts. However designers are still facing the challenge to accelerate the insertion of new materials for applications. One of the main challenge concerns the reduction of the material certification time which relies only on experimental procedure. Globally speaking, there is a need for a material definition and certification in a numerical form to meet platform requirement and that allows to reduce cost and development time of new material by replacing manual tests with advanced simulation. A comprehensive simulation process is then proposed and described. This process allows to define a complete test matrix in order to generate B-basis allowable for a given material system. Several aspects have to be considered.

As model-based systems engineering is proliferating throughout the aerospace industry as a method to manage the development of complex cyber-physical systems, opportunities to leverage formal methods for verification and validation purposes are significant. As a system model described in SysML can contain the level of semantics required to define strict system requirements, it is possible to create a translation tool to generate SRL (SADL (Semantic Application Design Language) Requirements Language) to leverage ASSERT™ (Analysis of Semantic Specifications and Efficient generation of requirements-based Tests) for verification and validation of the system requirements. SADL [13] is a controlled English grammar that translates directly into OWL (Web Ontology Language) [14]. As part of the validation of the SRL requirements, ASSERT™ leverages a theorem prover to look for conflict and completeness errors.

The ARP shall cover the objectives and activities of Verification & Vallidation Processes required to assure high quality and/or criticality level of an IVHM Systems and Software.

A Lycoming IO320 aircraft engine was run on different base fuels containing various percentages of methyl tertiary-butyl ether (MTBE). Vapor lock, vapor to liquid ratio (VLR), and Reid vapor pressure (RVP) tests were performed on the fuel mixtures to obtain a method that will provide a measure of the volatility of aircraft fuels for the purpose of aircraft certification. For the vapor lock runs the test fuel was heated to temperatures of 32, 38, 44, and 49 degrees Celsius (90, 100, 110 and 120 degrees Fahrenheit). A vapor lock run was performed for each combination of fuel mixture and tank temperature at fuel flow rates of 10, 20, 30, 40, 50 and 60 liters per hour. The quickest time to vapor lock was found to be at a fuel temperature of 44 degrees Celsius (110 degrees Fahrenheit) at takeoff power.

Hundreds of flight simulation experts from aerospace organizations worldwide – including airframe manufacturers, training device manufacturers (TDM), airlines, operators, and suppliers – will convene at RSi Visual Systems in Coppell, Texas, in September for the 2018 Flight Simulator Engineering and Maintenance Conference (FSEMC). Virtual reality (VR), motion cueing, ADS-B, pilot training for NextGen and SESAR, flight simulation training device (FSTD) technology insertion, and the pros and cons of commercial off-the-shelf (COTS) components top the list of discussion points for the annual conference.
