Addendum to type record. Avro "Lancaster" Mk.1 P. A. 474 Type record No. 1/P1/Lancaster. Investigation of boundary layer conditions on wings. M.O.S. Contract No.6/Aircraft/9807/C. B. 6(a)
Introduction
The investigation involves, briefly, the mounting of a wing
of 45' sweep-back in a dorsal position on the fuselage of
'Lancaster' P.A.474 such that wing incidence will be variable
in flight over a 20 range, i.e. ± 100.
A ‘partial chord’ technique for swept wings has been
established by the College using a similar wing mounting
configuration on an Avro 'Anson' Aircraft and this technique has
been applied to the current investigation
Continuous Open Access Special Issue "Aircraft Design": Number 3/2021
Following the successful initial Special Issue on "Aircraft Design (SI-1/2017)" and the relaunch with "Aircraft Design (SI-2/2020)", this is already the third SI in sequence named "Aircraft Design (SI 3/2021)". Activities in the past showed that aircraft design may be a field too small to justify its own (subscription-based) journal. A continuous open access special issue may fill the gap. As such, the Special Issue "Aircraft Design" can be a home for all those working in the field who regret the absence of an aircraft design journal. SI-3/2021 contains six papers (original research articles) about 1.) Oil Fumes in the Cabin and Flight Safety, 2.) Closed-Loop Flying Quality Requirements, 3.) Preliminary Design of a Medium Range Box Wing Aircraft, 4.) Influence of Novel Airframe Technologies on the Feasibility of Fully-Electric Regional Aviation, 5.) Design and Optimization of a Large Turboprop Aircraft, 6.) Sources of Onboard Fumes and Smoke
Continuous Open Access Special Issue "Aircraft Design": Number 2/2020
Following the successful initial Special Issue on “Aircraft Design (SI-1/2017)”, this is already the second SI “Aircraft Design (SI-2/2020)”. Activities in the past showed that aircraft design may be a field too small to justify its own (subscription-based) journal. A continuous open access special issue may fill the gap. As such, the Special Issue “Aircraft Design” can be a home for all those working in the field who regret the absence of an aircraft design journal. SI-2/2020 contains seven papers; an Editorial: 1.) "Publishing in 'Aircraft Design' with a Continuous Open Access Special Issue" and six Original Research Articles about 2.) Amphibious Aircraft Developments, 3.) Design Space Exploration of Jet Engine Components, 4.) Study of Subsonic Wing Flutter, 5.) Design Optimization of a Blended Wing Body Aircraft, 6.) Discrete Mobile Control Surfaces, 7.) Electro-Impulse De-Icing Systems
Hypersonic aircraft design
A hypersonic aircraft is designed which uses scramjets to accelerate from Mach 6 to Mach 10 and sustain that speed for two minutes. Different propulsion systems were considered and it was decided that the aircraft would use one full scale turbofan-ramjet. Two solid rocket boosters were added to save fuel and help the aircraft pass through the transonic region. After considering aerodynamics, aircraft design, stability and control, cooling systems, mission profile, and landing systems, a conventional aircraft configuration was chosen over that of a waverider. The conventional design was chosen due to its landing characteristics and the relative expense compared to the waverider. Fuel requirements and the integration of the engine systems and their inlets are also taken into consideration in the final design.

Trends in aircraft design
The improved performance of aircraft during the past decade has resulted
in the need for new design and production techniques. Particular examples are
integral construction and the use of sandwich panels. Although these processes
are costly, especially when applied to titanium and steel construction, their use
is likely to be necessary, at least to some extent. on many supersonic aircraft.
The supersonic airliner is no exception to this and the paper discusses the design
aspects of this type of aircraft which have a bearing on production problems. It
is concluded that more research aimed at reducing the cost of sophisticated forms
of construction is required
Rotor burst protection criteria and implications
Current aircraft design practices to minimize the hazard from rotor bursts are described. The consequences of non-contained engine failures and the impact of rotor burst protection systems on aircraft design are discussed
The teaching of aircraft design
Aircraft Design has been taught at the College of Aeronautics since
1946. The course is at postgraduate level and is of two years duration.
In the first year the students are given three exercises in component
design which aim to teach a logical approach and the fundamentals of the
subject. During the second year each student works as a member of a
team engaged in the design of a complete aircraft, which is chosen to be
of a type currently being investigated by industry. The project aircraft
invariably incorporates experimental features and the design work is
therefore of the nature of research
Advanced hypersonic aircraft design
The objective of this design project is to develop the hypersonic reconnaissance aircraft to replace the SR-71 and to complement existing intelligence gathering devices. The initial design considerations were to create a manned vehicle which could complete its mission with at least two airborne refuelings. The aircraft must travel between Mach 4 and Mach 7 at an altitude of 80,000 feet for a maximum range of 12,000 nautical miles. The vehicle should have an air breathing propulsion system at cruise. With a crew of two, the aircraft should be able to take off and land on a 10,000 foot runway, and the yearly operational costs were not to exceed $300 million. Finally, the aircraft should exhibit stealth characteristics, including a minimized radar cross-section (RCS) and a reduced sonic boom. The technology used in this vehicle should allow for production between the years 1993 and 1995
Proceedings of the 11th European Workshop on Aircraft Design Education
These are the Proceedings of the 11th European Workshop on Aircraft Design Education (in short: EWADE 2013). The workshop took place from 17. to 19.09.2013 in Linköping, Sweden. EWADE 2013 was for the first time integrated into the CEAS European Air & Space Conference. Location was the congress center located right in the heart of the city of Linköping. The workshop was organized by Prof. Dieter Scholz, Aircraft Design and Systems Group (AERO), Hamburg University of Applied Sciences, in close cooperation with Prof. Petter Krus, Head of the CEAS2013 Programme Committee and Head of the Division of Fluid and Mechatronic System, Linköping University and Dr. Tomas Melin, CEAS 2013 Programme Secretary and Research Associate in the Division of Fluid and Mechatronic System, Linköping University. The workshop had 4 technical sessions: EWADE 1 - Presentations from EWADE Founders and Hosts. EWADE 2 - Teaching and Research Activities in Aircraft Design. EWADE 3 - Aircraft Design Studies. EWADE 4 - Aircraft Design - Methods and Tools. The proceedings cover all 19 presentations. 6 of these presentations are accompanied by full text papers
