MODUK DEF STAN 00-970: PT 9: VOL 2 PDF

INTRODUCTION

This Part states those tests which shall be made to demonstrate that the rotorcraft can be controlled satisfactorily and is adequately stable in the air, and on the ground, in accordance with the requirements of Part 6.

Each chapter of this Part contains tests of the rotorcraft under a specific flight condition and is arranged in accordance with a standard layout, the paragraphs being grouped under headings in the following sequence :

Object;

Relevant design requirements;

Applicability ;

Equipment;

Loading;

General test conditions;

Notes.

APPLICABILITY 

The tests contained in this Part apply to all new types of rotorcraft.

The tests are to be made in full on a representative sample of the rotorcraft. The tests shall be repeated on other samples of the rotorcraft as agreed between the Rotorcraft Project Director and the Contractor to ensure that variations between individual rotorcraft in the fleet do not adversely affect the demonstrated handling characteristics. However, when more than one loading condition is stipulated, the repeat tests need only be made at the loading at which the behaviour was least satisfactory. When modifications liable to affect the aerodynamic characteristics of the rotorcraft are incorporated, the first rotorcraft so modified shall be tested at the most adverse loadings. In addition, tests at other loadings shall be made, at the discretion of the Rotorcraft Project Director, to ascertain whether the modification is likely to produce more adverse effects at other loadings.
