The Journal of the Royal Aeronautical Society, 1948
It is only within recent years that the helicopter has emerged from the experimental aircraft category to a position in which it can be considered as an effective operational and commercial means of aerial transport. The development of the helicopter to its present stage is due to extensive work in many countries, particularly in America, and it is ...

The Development and Flight Testing of Helicopters
The Journal of the Royal Aeronautical Society, 1960SummaryThe successful development of a helicopter and its introduction into service may be influenced by several factors but a well co-ordinated development programme is by far the most important. A practical and realistic balance between representative ground tests and the subsequent flight proving is essential if the project is to be completed within

Vibration Testing of Helicopters
The Aeronautical Journal, 1970The purpose of my contribution is to explain the need for dynamic testing in terms of defining the design problems where testing is required to assist or substantiate decisions made in the light of mainly theoretical evidence in the initial stages of design before hardware becomes available for testing.I have interpreted the title in the broadest sense

The Programme of Development Testing for a Helicopter
The Journal of the Helicopter Association of Great Britain, 1959The Chairman, in opening the meeting, said he was very glad indeed to see so many members present at the first meeting of the new Session, especially as, some of them had, no doubt, been up half the previous night watching the television programme (to hear the election results)It was a pleasure to welcome tonight’s lecturer, Mr Newberry, who, since ...

Test duration in choice of helicopter maintenance policy
Reliability Engineering & System Safety, 2004Abstract In the course of a review of the maintenance policy for a certain type of helicopter, it was found necessary to determine whether the frequency of one of the scheduled tests could be reduced without a shorter mean time between failures (MTBF). A sequential-testing procedure was worked out for an experiment in which hypotheses on the ratio of

An Experimental Test Bed for Small Unmanned Helicopters
Journal of Intelligent and Robotic Systems, 2008This paper introduces a custom experimental test bed for the evaluation of autonomous flight controllers for unmanned helicopters. The development of controllers for unmanned helicopters is a difficult procedure which involves testing through simulation at first, and then actual experimentation on real vehicles.

A Test Plant for Helicopter Engines
The Journal of the Royal Aeronautical Society, 1957This Note describes the design and construction of a “ Tilting Test Bed ” for helicopter engines for Alvis Ltd., for which some onerous requirements were laid down (Fig. 1). The most important of these were that:—(i)Readings of engine torque and b.h.p.

The Forest Survey Tests the Helicopter
Journal of Forestry, 1947Abstract The helicopter has demonstrated that it can be used successfully for a variety of peace-time purposes. Because of its ability to fly slowly and at low altitudes it would seem to be particularly useful on timber surveys of various kinds.
