Energy recovery from landing aircraft

Paul Stewart

This is an EPSRC funded project:

  • EP/H004351/1: Feasibility Study, Energy Recovery from Landing Aircraft. Collaborating company: EADS Innovation Works

which is run by Prof Paul Stewart and Dr David Waugh in the School of Engineering at the University of Lincoln. It is one of a portfolio of projects awarded from the EPSRC Sandpit Low Carbon Airports. All the project researchers and PIs associated with this Sandpit are members of the Airport Energy Technologies Network (AETN), which is hosted here at Lincoln University.

Rationale

On account of the enormous pressures on numerous industries to cut down upon their carbon emissions it is not surprising to identify that one such industry is that of the airline industry. With aircraft transport becoming more widely used, along with aircraft becoming larger (for example the Airbus A380), it is possible for one to realize the large potential gains that recovering energy from aircraft would offer in terms of feeding that energy back into the national grid or storing the energy locally on the aircraft for use in recovered energy assisted take-off.

How much energy is associated with a landing aircraft?

We can make assumptions to illustrate the magnitude of kinetic energy available via a small commercial airliner:

Taking an Airbus A320 with landing mass m = 6.5×104 kg, with landing speed ν = 61.69 ms-1

we can calculate the kinetic energy E = 1.248 J.

Assuming a runway length of 1.2km gives us a linear acceleration of -1.59 ms-2

and a stopping time of 38.80s, which gives us a peak transferrable power of 3.2MW

Therefore, it is possible to realise that for a typical Airbus A320 the potential energy which could be recovered is very large with peak transferable powers of up to 3.2 MW being available. Furthermore, this becomes an even more attractive means when taking into account multiple landings as busy airports which leads to average transferable powers of up to 1 MW. In addition to this, one can see that over time aircraft will become bigger having even larger landing weight, such as the Airbus A380,  which will increase the potential power output by up to 10 times the figures stated here for the Airbus A320


successful seminar – ‘Using lasers to modulate biological cell response’

Dr David Waugh giving an open seminar

Summary
Wed 6th April 2011 @ 2:00p.m. – 3:00p.m. Lincoln School of Engineering Open Seminar Series. Dr. David Waugh gave an open seminar about ‘Using lasers to modulate biological cell response’ in one of Lincoln:Engineering’s seminar rooms.

Abstract

With an aging population there is an ever growing demand on medical facilities, especially with regard to biological implant technology. Laser surface treatment offers a unique way of tailoring surfaces to manipulate cell response in order to reduce and predict clinical failure. This open seminar will give you an insight into the multidisciplinary research carried out by Dr. Waugh, a Research Fellow in the Lincoln School of Engineering. The seminar will discuss work in the field of laser-modified wettability characteristics and how they can be employed to determine the biofunctionality of a given material. Furthermore, the future for this research will be discussed including potential use of this technology in stem cell growth and manipulation.

Dr. David Waugh Ph.D., MSc. MPhys, MIET, AMInstP is currently a Research Fellow at the Lincoln School of Engineering. He is currently undertaking a feasibility study modelling and simulating a number of techniques to harness the kinetic energy from landing aircraft, under the supervision of Prof. Paul Stewart.

In addition, Dr. Waugh is furthering his Ph.D. research into the application of lasers in life sciences. This involves the laser surface treatment of biomaterials, specifically polymers, to modify the surface topography and surface chemistry to enhance biological cell growth. This is carried out in the endeavour to counter the failure rates of biological implants so that the need for unnecessary corrective surgery is considerably reduced.

Dr. Waugh has also carried out significant studies into the modification of wettability characteristics of laser surface-modified polymeric materials. With this in mind, he endeavours to quantitatively link the wettability characteristics of a material to its bioactive nature in the hope to give clinicians a platform from which tailored biomaterials can be produced. This would allow clinicians to have the ability to confidently predict cell response to a specific material.

His Ph.D. entitled “Laser surface treatment of nylon 6,6 for the modification of wettability characteristics and subsequent enhancement of osteoblast cell response” was carried out in the Wolfson School of Engineering at Loughborough University, under the supervision of Dr. Jonathan Lawrence. His MPhys. and MSc. in Physics with lasers and optics was carried out at the University of Hull.

Dr. Waugh actively publishes his work through books and international journals. In addition, he has attended and presented at a number of national and international conferences such as the International Congress on the Applications of Lasers and Electro-Optics (ICALEO). Furthermore, he has been a reviewer for a number of academic journals such as Lasers in Engineering, Surface and Coatings Technology and the Institution of Mechanical Engineers, Part C; Journal of Mechanical Engineering Science.
