Spin and Spin Recovery
90 Spin and Spin Recovery Dragan Cvetkovi´c1, Duško Radakovi´c2, Caslavˇ Mitrovi´c3 and Aleksandar Bengin3 1University Singidunum, Belgrade 2College of Professional Studies "Belgrade Politehnica", Belgrade 3Faculty of Mechanical Engineering, Belgrade University Serbia 1. Introduction Spin is a very complex movement of an aircraft. It is, in fact, a curvilinear unsteady flight regime, where the rotation of the aircraft is followed by simultaneous rotation of linear movements in the direction of all three axes, i.e. it is a movement with six degrees of freedom. As a result, there are no fully developed and accurate analytical methods for this type of problem. 2. Types of spin Unwanted complex movements of aircraft are shown in Fig.1. In the study of these regimes, one should pay attention to the conditions that lead to their occurrence. Attention should be made to the behavior of aircraft and to determination of the most optimal way of recovering the aircraft from these regimes. Depending on the position of the pilot during a spin, the Fig. 1. Unwanted rotations of aircraft spin can be divided into upright spin and inverted spin. During a upright spin, the pilot is in position head up, whilst in an inverted spin his position is head down. The upright spin is carried out at positive supercritical attack angles, and the inverted spin at negative supercritical attack angles. According to the slope angle of the aircraft longitudinal axis against the horizon, spin can be steep, oblique and flat spin (Fig.2). During a steep spin, www.intechopen.com 2210 MechanicalWill-be-set-by-IN-TECH Engineering the absolute value of the aircraft slope angle is greater than 50 degrees, i.e. -
CAA Doc 743 Civil Air Displays a Guide for Pilots

On average there are over 250 civil flying displays Guidance for display each year attracting in excess of two million pilots spectators. It is of the utmost importance in the interests of public and personal safety, that those Managing the risk who participate in such displays operate to the highest standards. These notes are intended to Planning your provide advice to display pilots to help them display avoid the pitfalls which have been experienced in the past. Practising for your display The air show Display day Post display © Andrew Critchell 1 the law The rules governing the conduct of civil air displays in the United Kingdom are given in the current Air Navigation Order, The Rules of the Air Regulations and comprehensively explained in CAP 403 – “Flying Displays and Special Events: A Guide to Safety and Administrative Arrangements”. guidance for display pilots Display flying, especially aerobatics, is a specialised form of flying that frequently involves flying the aircraft close to the edges of the permitted flight envelope. Regrettably, most years, a small number of pilots are killed whilst displaying. Many of these pilots were highly experienced and extremely competent in their particular aircraft and display. What can be done to minimise the risk? managing the risk personnel fitness There are a large number of factors which affect the outcome of a particular flight. Many of them are encountered well before the pilot gets anywhere near the aircraft. -

Unusual Attitudes and the Aerodynamics of Maneuvering Flight Author’S Note to Flightlab Students
Unusual Attitudes and the Aerodynamics of Maneuvering Flight Author’s Note to Flightlab Students The collection of documents assembled here, under the general title “Unusual Attitudes and the Aerodynamics of Maneuvering Flight,” covers a lot of ground. That’s because unusual-attitude training is the perfect occasion for aerodynamics training, and in turn depends on aerodynamics training for success. I don’t expect a pilot new to the subject to absorb everything here in one gulp. That’s not necessary; in fact, it would be beyond the call of duty for most—aspiring test pilots aside. But do give the contents a quick initial pass, if only to get the measure of what’s available and how it’s organized. Your flights will be more productive if you know where to go in the texts for additional background. Before we fly together, I suggest that you read the section called “Axes and Derivatives.” This will introduce you to the concept of the velocity vector and to the basic aircraft response modes. If you pick up a head of steam, go on to read “Two-Dimensional Aerodynamics.” This is mostly about how pressure patterns form over the surface of a wing during the generation of lift, and begins to suggest how changes in those patterns, visible to us through our wing tufts, affect control. If you catch any typos, or statements that you think are either unclear or simply preposterous, please let me know. Thanks.

Tiger Moth Aerobatics
TIGER MOTH AEROBATICS By David Phillips Preamble I was recently asked to provide some notes on Tiger Moth Aerobatics to be used as an appendix to a Warbirds aerobatic training syllabus. As I wrote these notes, I was constantly aware of a feeling of: “ Well, this is how I do it, but what is the correct or ideal way … ?” I have never seen any formal notes on Tiger aerobatics. The following represents most of what I know about aerobatics in the Tiger. The vast majority of it has been taught or shown to me by others, or has been pinched from Neil Williams’s book on the subject. I think it (my brief, not Neil’s!) is probably flawed in places, and it certainly is not supposed to be authoritative. My reasons for presenting it here are mostly selfish — I would like to increase my knowledge of the subject. So I am inviting criticism of, and additions to, what I have written below. “ Additions” includes alternative ways of skinning the cat. In particular I would be keen to hear from people who grew up with Tigers, as they probably have clearer and purer recollections of the original way of doing things. Also knowledge of or anecdotes about flick manoeuvres, bunts, inverted spins and inverted flying are most welcome. For example, some flight manuals prohibit bunts and outside loops — but one of Alan Cobham’s Tigers did 1500 or so of them in the 1930s. So, if you have anything to offer on the subject please contact John King and myself via the Contact page on the website. -
