Reverse Thrust

A number of new considerations are beginning to influence the design of development aeroengine test facilities due to technological, environmental and regulatory developments. Whilst the technological developments are of an evolutionary nature, the other developments, for example, the imposition of mandatory environmental noise constraints and the requirement to perform in-cell reverse thrust testing for early Extended Twin Operations certification, may impose step changes in test facility design. This paper examines the influence of these new developments on test cell design and describes how the new requirements were integrated with the traditional considerations in the design of a new “sea level” Test Bed in Derby, UK.

Wetted Surface Area

This paper describes hydrodynamic model tests of Wing in Surface Effect (WiSE) Craft. These craft  was fitted with  stephull  form in different location on longitudinal flat bottom (stepedhull planning craft) to determine the influences of sticking and porpoising motion performances. These motions are usually occured when the craft start to take-off from water surfaces. The test models with scale of 1 : 7 were comprised of 4 (four) stephull models and 1 (one) non-stephull model  as a comparative study. The hydrodynamic  tests were performed with craft speed of 16 – 32 knots (prototype values) in Towing Tank at UPT. Balai Pengkajian dan Penelitian Hidrodinamika (BPPH), BPPT, Surabaya. The resistance (drag) was measured by dynamo meter and the trim of model (draft changing at fore and aft  of model due to model speed) was measured by trim meter. By knowing the value of model trim, the wetted surface area can be determined. Then, the lift forces were calculated based on these measured values. The model test results were presented on tables and curves.  Test results show that models  with step located far away from center of gravity of the WiSE craft tend to porpoising and sticking condition, except if the step location on the below of these center of gravity. While model without step tends to sticking conditions.
