Project Description

The project aims to provide an answer to the question of what the optimal Diesel engine for a light helicopter is, taking into consideration its expected performance and design capacity. In order to fulfill this goal, a multi-criteria analysis will be undertaken to cover the issues of mechanical and thermal load and possible interactions with a helicopter frame.
The project results can be recognized as designing clean energy solutions for light helicopters. The use of turbocharged engine with self-ignition and an electronic control system can substantially reduce the negative impact on the environment by decreasing:

  • toxic substance emission;
  • fuel consumption and therefore carbon dioxide emission;
  • noise levels.

The work comprises three major phases:

  1. Optimal Diesel Engine Specification
  2. Engine/Rotorcraft Integration Study
  3. Environmental Impact Analysis

I) Optimal Diesel Engine Specification
The optimal diesel engine design for the light helicopter is assumed to reach ideal helicopter characteristics and fulfill the environmental impact reduction expectations according to the Acare goals for 2020 as defined in the call. This phase will be preceded by an analysis of the flight scenario. The helicopter performance is inseparably related to the load at the input to the propulsion system.

II) Engine/Rotorcraft Integration Study
This study is conducted to evaluate the integration of the proposed optimal diesel engines into 2t class light helicopter. The engine and its subsystems can be built on the ideal platform which requires the following connections:

  • thermodynamic – to study the engine heat transfer to the engine bay, cooling and ventilation methods,
  • mechanic - to study the vibrations levels and to develop methods for its reduction, and thus to fix the engine,
  • electronic – to define the engine control system and to integrate with the helicopter electrical and avionics system,
  • hydraulic and pneumatic - to integrate the fuel system, cooling, air supply, engine exhaust systems inside the helicopter.

III) Environmental Impact Analysis
To establish the environmental benefits of the diesel engine technologies, mathematical models will be created to predict the performance and environmental impact of a classic turboshaft and an advanced diesel engine light helicopter, incorporating project technology developments.
