Major new KTP for the School of Engineering

Paul Stewart

Dr Jill Stewart, Senior Lecturer in Thermofluids in the School of Engineering has secured a 3-year KTP grant in collaboration with Napier Turbochargers Lincoln.

The project will develop a design methodology of turbocharger compressor impellers that are resilient to typical manufacturing tolerances thus maintaining efficiency and reducing manufacturing non-conformance cost.

The project is anticipated to commence in August 2011

Napier Turbochargers is a wholly self-owned company, having previously been owned by Siemens Power Generation, specifically Siemens Industrial Turbomachinery Ltd being based on the same site in Lincoln when it bought the neighbouring Alstom Power Turbines in March 2003; Alstom (former GEC-Alsthom) had owned the company since GEC bought English Electric in the late 1960s.

Best paper prize for School of Engineering academics

Prof Paul Stewart and Dr Jill Stewart from the School of Engineering in collaboration with Dr Dan Gladwin from the University of Sheffield have been awarded the Charles Sharpe Beecher Prize by the Institution of Mechanical Engineers for their 2010 paper

Multi-objective evolutionary–fuzzy augmented flight control for an F16 aircraft. Proceedings of the IMechE, Part G: Journal of Aerospace Engineering, 224 (3). pp. 293-309. ISSN 0954-4100

The prize is awarded for the best paper on an aerospace subject published by the Institution in the previous year.

The paper examines the application of Artificial Intelligence techniques to the flight control system of the Lockheed Martin F16 Fighting Falcon. In particular, the modified controller aims to enhance the performance of the flight controller to reduce pilot fatigue during extended combat flight manoeuvres.

The F-16 is a single-engined, supersonic, multi-role tactical aircraft. The F-16 was designed to be a cost-effective combat “workhorse” that can perform various kinds of missions and maintain around-the-clock readiness. It is much smaller and lighter than its predecessors, but uses advanced aerodynamics and avionics, including the first use of a relaxed static stability/fly-by-wire (RSS/FBW) flight control system, to achieve enhanced maneuver performance. Highly nimble, the F-16 can pull 9-g maneuvers and can reach a maximum speed of over Mach 2.

The Prize will be awarded at the Annual General Meeting and Awards Ceremony at the IMechE London headquarters on 17th May 2011

Engineering School facilitates major equipment grant from Lincoln Council to aid local businesses

EOS P380 Rapid Prototyping Machine

Lincoln City Council has secured approval to purchase a Rapid Manufacturing Machine in order to establish a facility which is accessible to local businesses as part of a commitment to promote and encourage the growth of engineering and innovation activity in the local economy.

The School of Engineering is fully committed to this initiative, which is part of its engagement process with local industry and a long term close collaborative relationship with the City Council.

Dr Jonathan Lawrence, who is Reader and Head of the  Laser Materials Processing Group in the School, has sourced a machine in China, and will be travelling out to Shanghai in the near future to perform a technical verification before the unit is shipped to Lincoln.

The School will be working closely with the Council to promote the usage of the facility, and will be subsequently working with local businesses to fully utilise it.

The EOS P380 machine uses a high-powered laser, which fuses metal powder into a solid part by melting it locally using the focused laser beam. Parts are built up additively layer by layer. This process allows for highly complex geometries to be created directly from the 3D CAD data, fully automatically, in hours and without any tooling, producing parts with high accuracy and detail resolution, good surface quality and excellent mechanical properties.

Lincoln School of Engineering is part of a global consortium which will be kicking off an EU Framework 7 Programme Collaborative Project in September 2011.

The project is MAAT Multibody Advanced Airship for Transport, and is led by Professor Antonio Dumas at the University of Modena, Italy.

Principal Investigator at the University of Lincoln is Prof. Paul Stewart, and Co-Investigator is Prof. Chris Bingham, both of the School of Engineering.

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.
