Setting up the engine laboratories in the New School of Engineering

Engine lab control room for the Free-Piston Engine

It’s only 12 weeks until we move into our new building. On the ground floor are some of our experimental laboratories, in particular our engine test cells. The cells each have an associated control centre separated by safety materials, from where experiments can be conducted remotely.

Pictured is the control centre for the Lotus Free-Piston Engine when it was under development in the Test Cells at the University of Loughborough, with the actual engine cell visible in the background through double safety glass.

The task I’ve got now is to move our experimental engines into the new build, and get them all running, commissioned and most challenging of all, correctly wired up into the data acquisition and control systems.

The picture of the Lotus engine gives an indication of the amount of sensor and actuator cabling associated with each engine.

Engines are generally under computer control via either LabView, or running Matlab and Simulink developed control algorithms under DSpace. It’s quite rare for me to hand write code these days, DSpace compiles control structures from simulink into C, and downloads it onto ta converters.he host control microprocessor and associated A-D and D-A converters.

A lot of our engine laboratory equipment has been stored at the ThinkTank until the move, so we’re just starting the process of going through it all and allocating space.

The Lotus Free Piston Engine project story – people

After delivery to the engine test cells at Loughborough University AAE dept., it took a significant amount of time to put together the control system instrumentation, and the control architectures necessary to run the engine under Labview, and DSpace.

This part of the story is the people behind developing this part of the project.

First up is Dr Ben Taylor, who at the time was one of my Post-Doctoral researchers at the University of Sheffield Department of Electronic and Electrical Engineering, and is currently a Research Fellow there in the Department of Automatic Control and Systems Engineering. Ben designed and built the 100kW four-quadrant power converter which in the early stages of the project drove the permanent magnet servo-motor attached to the end of the tethering crankshaft. This arrangement allowed us to make the initial development happen relatively safely, without the danger of losing control and blowing up the engine. Later developments are untethered from the crankshaft and truly ‘Free-Piston’

Ben also designed the control system for the servo-motor, based around a TI Digital Signal Processor (DSP) which allowed accurate, real-time control of the motor currents, and position/velocity control of the motor, interfaced to a DSpace real-time controller.

Ben subsequently moved on to work for myself and Prof Chris Bingham on a RDA funded project on intelligent heating controls and methods for domestic houses.

The power converter which Ben designed and built is now in use driving the linear electrical machine embedded in the engine, whilst the drive of the crankshaft servo-motor has been take over by a custom designed four-quadrant inverter designed and installed by Control Techniques

Proton Energy and Sanswire High Altitude Commercial Rigid Airships

The MAAT project overcomes structural and physical limits of airplanes in cruiser/feeder operation. It aims to investigate an airship cruiser-feeder global transport system for medium and long range transports.

The MAAT system is composed by three modules.

  1. PTAH (Photovoltaic Transport Airship for High-altitudes) is a heavy payload cruiser which remains airborne on stable routes;
  2. ATEN (Air Transport Efficient Network feeder) is aVTOL feeder airship by gas buoyancy linking the cruiser to the ground;
  3. AHA (Airship Hub Airport) is a new concept of low cost vertical airport hub joinable by ATEN, easy to build both in towns and in logistic centres.

The strengths of the MAAT concept are:

  • standardized and modular global air transport system;
  • operative altitudes higher than traditional civil routes;
  • heavy payload, low cost of transportation and non-stop flight;
  • possibility to act as a flying integrated logistics centre;
  • self sufficient by photovoltaic propelling system;
  • increased safety to prevent crashes and long evacuation times;
  • hovering ability to simplify cruiser/feeder engagement;
  • cruiser/feeder transfers in motion;
  • VTOL ground operations;
  • silent landing and take-off operations;
  • cost effective, light and easy to deploy structures on the ground;
  • reduced fuel consumption and carbon emissions

The MAAT Project aims to study the system and its components in a full structured systemic approach and to define:

  1. the general design of cruiser and feeder, to optimize aerodynamics and photovoltaic energy;
  2. the preliminary structural draft of cruiser, feeder and hub;
  3. control systems, procedures and codes for stability and flying attitude control;
  4. electrical propulsion systems able to overcome the problems related to the low air density;
  5. operative procedures for rendezvous and joining operations;
  6. internal design of cabins and cargo;
  7. study and design of cruiser/feeder connections;
  8. passive and active safety systems.
