Acoustic Analysis of Counter-Rotating Open Rotors with a Locked Blade Row
in AIAA Journal
Description | We have addressed gaps in knowledge regarding novel rotorcraft systems. We demonstrated advances in a number of key areas, including the aero-mechanics of tilt-rotor vehicles, multi-rotor configuration, engine design optimisation and aero-acoustics. We developed numerical methods for simulating novel flight platforms. We are using numerical models to simulate complete rotorcraft, and to understand which are the flight limitations and safe areas to fly. The research continues beyond this award with projects that are have hybrid funding, including contributions from industry. |
Exploitation Route | We develop models that can be used by industry to deal with their new design challenges. We meet regularly with industry and other sponsors to understand where the needs and gaps are, and we can fill these gaps by doing the fundamental research. |

Title | EngineTool: calculation of turboshaft engine performance and emissions |
Description | This is a computer model developed to determine rotorcraft engine performance and exhaust emissions. It is integrated with other software from the research community and in the MENTOR project. |
Type Of Material | Computer model/algorithm |
Year Produced | 2021 |
Provided To Others? | Yes |
Impact | Ability to estimate exhaust emissions, possible integration with ASD-B flight trajectories to estimate helicopters fuel consumptions and emissions over realistic flight trajectories |
Title | FLIGHT: a flight simulation code for environmental emissions (noise and engine exhausts) |
Description | This computer model has been further verified to compare measured noise data at high altitude with simulations. Verifications have been carried out for long range noise propagation across atmospheric layers of stratified temperatures, pressures and winds. |
Type Of Material | Computer model/algorithm |
Year Produced | 2020 |
Provided To Others? | Yes |
Impact | Research generated interest in recent years from members of the professional community, including noise monitoring organisations (ICCAN), local airport authorities (for example, Edinburgh) and academic researchers. |
Title | EngineTool: software for the simulation of turboshaft (helicopter) engines |
Description | This computer codes simulates turboshaft engines at all flight conditions, and produces outputs such as fuel flow, mass flow rates, shaft power, temperatures and pressures in critical sections of the engine, and emission data, when possible. |
Type Of Technology | Software |
Year Produced | 2020 |
Impact | This software is being integrated with the University of Liverpool Software Federation for Helicopter Flight Simulation |
Title | FARP: Computer code for the simulation of conventional helicopter aero-mechanics |
Description | The software uses novel numerical methods to simulate the aero-mechanics of a conventional helicopter, including engine aero-thermodynamics, trim conditions, blade flapping, aerodynamics, flight performance. |
Type Of Technology | New/Improved Technique/Technology |
Year Produced | 2019 |
Impact | No impact yet achieved. |
Title | Multi-Component Free Wake Code for Rotors |
Description | The premise of the code is a free wake model that can numerically integrate the wake dynamics of an arbitrary number of user-specified components in time and space. The types of components that can currently be modelled are: • Symmetric fixed-wings • Propellers • Articulated rotors For rotor-type components, the blade/rotor dynamics are also integrated in time in parallel with the wake dynamics. Simulations are currently limited to components flying along fixed trajectories. Furthermore, the configuration of the component is fixed throughout the simulation, i.e., there are no time-dependent control inputs. There is currently no facility to trim any of the components to any specified load targets (e.g. a thrust/power/lift target) or to modify the rotational speed of any rotary-wing components (e.g. variable RPM propellers). However, several rotary-wing components, all with different rotational speeds, can be specified. |
Type Of Technology | New/Improved Technique/Technology |
Year Produced | 2022 |
Impact | The code is part of the novel tools developed under the MENtOR programme. It allows expert engineers and researchers to model multi-rotor configuration, both rotorcraft and fixed-wing aircraft. |
Title | ROMA: Rotor aerOMechanics Analysis |
Description | ROMA is used for performance predictions of isolated rotors and propellers. TARA is used for performance predictions of tiltrotor aircraft, though different aircraft can be simulated due to the object-orientated undertaken within the code. |
Type Of Technology | Software |
Year Produced | 2020 |

Title | Software: TandRot, aeromechanics code for simulation of tandem helicopters |
Description | This code simulates the aerodynamics, flight dynamics, engine performance, mission analysis, direct operating costs, and other performance metrics of tandem helicopters such as the CH-47. |
Type Of Technology | Software |
Year Produced | 2020 |
Impact | Code now used routinely for teaching at the post-graduate level and for CPD courses to professional engineers |
Title | TARA: Tiltrotor AeRomechanics Analysis |
Description | TARA, like ROMA, is run from a series of input files that characterise the configuration, geometry, aerodynamics and interactions between several airframe components: 1. Fuselage (point loads) 2. Rotors (blade element theory) 3. Wing (strip theory) 4. Empennage (strip theory) These components are integrated together to form a single flight vehicle. Spreadsheet templates are available to create the input files for the different components. TARA implements an inverse simulation to trim the aircraft to a desired operating condition. Currently, the code only facilitates longitudinal flight but upgrades will extend this to lateral and directional flight. Improvements to the aerodynamic solvers and interaction models/data are also planned upgrades. |
