Nowadays, almost all General Aviation piston-powered aircrafts are powered by Avgas fuel. For decades, piston engines like Lycoming and Continental were allowed to burn only this type of fuel, which is characterized by high-octane values, very low vapor pressure indexes and high costs because of its poor production quantity, tracked and certified production and high performances. The “compression ignition” engine can provide a fuel consumption reduction from 30% to 50% compared to Avgas engine. An additional benefit of the replacement of Avgas piston engine with a diesel engine is obtained due to the reduced fuel price. This “compression ignition” piston engines are able and certified to operate with kerosene and/or Jet fuels, so their use is justified in areas, such as Europe, Africa, Russia, China and many others, where aviation gasoline (Avgas, also known as 100LL) cost is significantly higher than jet fuels. Therefore the objective of this project is to demonstrate the feasibility of an efficient “diesel” engine installation on a FAR/EASA Part23, 9 to 11 seats twin engine aircraft configuration and reduce as much as possible the related increase in drag, respect to a conventional engine, by using Computational Fluid Dynamics (CFD) in the design phase. In order to achieve this goal the SR460, a six-cylinders, air/oil-cooled turbo-diesel engine produced by SMA, will be used as reference and installed on the TECNAM P2012 TRAVELLER aircraft. The main advantages are reported as following: • The average fuel consumption will be of around 45kg/hr/engine against an average of 130kg/hr of a turboprop engine; • P2012 will be the first twin engine aircraft available in both "Avgas" and "kerosene" capable variants; • P2012 with SR460 will have a very competitive acquisition cost, comparable to the same-passengers’ capability of the single engine turboprop.

The proposal addresses the topic: “ATS Level Business Jet 2035 forecast” (JTI-CS2-2016-CFP05-TE2-01-03) and it is devoted to perform forecasts for business jet traffic, in terms of fleet and movements starting from 2015, passing by 2020/2025/2030 until 2035, with a detail at country/region/world levels. Where gaps exist, an estimate will be made based on the methodology. More in detail the Technology Evaluator has requested: “The global fleet development and the share of European (Clean Sky) Aircraft” and “the development of movements per country and between Origin and Destination airports”. The overall objective of the project is: to analyse existing forecasts about volume and movements of Business jets in the relevant years, to establish a new forecast about bizjet fleet up to 2035 and the number of bizjet movements at country/region/world levels, to estimate the market share of European products in the market. Generally the forecast of business jet volumes depends on technology progress and the associated cost reductions, demand related to “Gross Domestic Product” development and accessibility. This means that the future of the bizjet transport also depends on developing new concepts of operation, aircraft concepts and business models and plans. After the assessment of the existing forecasts by different sources and CleanSky related actions and outcomes, the methodology of harmonization and improvement of the business jet forecast will be defined and finalized. The methodology based on a new dedicated demand equation will include: definition of the economic, technology and societal drivers, harmonized business models and business plan as well scenarios to create an improved forecast model. The outcomes will be completed in case of gaps and shared with the involved stakeholders and Clean Sky Topic Management. In this way, the forecasts will allow to make better characterisation of the measurable effects of technologies developed in CleanSky 2.

This proposal addresses the topic: “ATS Level SAT 2035 forecast“ (JTI-CS2-2016-CFP05-TE2-01-05) and it is devoted to perform forecasts for small air transport traffic, in terms of fleet and movements starting from 2015, passing by 2020/2025/2030 until 2035. This forecast will be detailed at country/region/world levels. Where gaps exist, an estimate will be made based on the methodology. More in detail the Technology Evaluator has requested: “The global fleet development and the share of European (Clean Sky) Aircraft” and “the development of movements per country between origin and destination airfields”. The overall objective of the project is: to analyze existing forecasts about the volume and movements, to establish a new forecast about the air traffic and fleet of small air transport up to 2035 at country/region/world levels and to estimate the market share of European products in the market. Generally the forecast of small air transport volumes depends on: technology progress and the associated cost reductions, demand related to “Gross Domestic Product” development and accessibility. This means that the future of the small air transport also depends on developing new concepts of operations, aircraft concepts business models and, business plans. After the assessment of the existing forecasts by different sources and CleanSky related actions and outcomes, the methodology of harmonization and improvement of the small air transport forecast will be defined and finalized. The methodology based on a new dedicated demand equation will include: definition of the economic, technology and societal drivers, harmonized business models and business plan as well scenarios to create and improved forecast model. The outcomes derived by such methodology will be completed (in case of gaps) and shared with the involved stakeholders and CleanSky Topic Management in order to make an easier evaluation of the measurable effects of technologies developed in CleanSky 2.

This proposal is devoted to perform forecasts for rotorcraft traffic, in terms of fleet and movements starting from 2015, passing through 2020/2025/2030 until 2035. Three objectives are performed: (1) to analyze existing forecast about the volume and movements of Rotorcrafts in the relevant years, (2) to establish a new forecast about the fleet of rotorcraft up to 2035 and the number of rotorcraft movements, (3) to estimate the market share of European products in the related market. The study will focus on civil applications including conventional rotorcraft, high-speed rotorcraft and autogyro’s. It also includes both piloted and unmanned vehicles. For the near future, the use of rotorcraft for passenger transport, is expected to develop rapidly by providing shuttle operations from city heliports to airports, or between cities without airports or connecting islands to mainland with limited ground infrastructure. Generally, the forecast of rotorcrafts traffic volumes depends on: (i) technology progress, (ii) demand related to Gross Domestic Product development and (iii) accessibility. The innovation theory teaches us, that the forecast also depends on: (iv) developing new concept of operations, (v) new rotorcraft types based on innovative technologies and (vi) new mission types. This means that the future market opportunities will not only depend on replacements and natural growth in demand, but also on new opportunities that can create an additional attractiveness for rotorcraft travel. The proposed project will take into account all the previous elements and the improvement of the rotorcraft forecast will be based upon a new dedicated demand equation, including definition of the economic, technology and societal drivers, harmonized business models and business plans. The objectives will be possibly quantitatively measured and the forecast validated.
