Embodiment

[0071] The present invention will be described in further detail below in conjunction with the implementation of the AC313 helicopter life-saving performance test flight at sea. The specific steps are as follows:

[0072] [1] Flight test project design

[0073] According to step 1 of the technical plan, according to the characteristics of helicopter life-saving winch rescue at sea, the flight test capability requirements and flight test subject design are carried out, as follows:

[0074] 1) The winch life-saving wind resistance ability, verify the side wind resistance ability of the winch for winch life-saving; simulate and verify the feasibility of the winch to perform the sea life-saving flight test process method;

[0075] 2) Rescue dynamic stability, evaluate the stability of the helicopter in the state of rescue flight at sea;

[0076] 3) Under different sea conditions, verify the whole process of rescue at sea, verify the manoeuvrability and implementability of helico...

Abstract

The invention belongs to the technical field of helicopter flight tests, and discloses a civil helicopter marine lifesaving performance verification test flight method. The method comprises the following steps: formulating test flight requirements and test requirements of risk subjects such as offshore lifesaving according to regulations such as CCAR29R1 in Airworthiness Specification of Transportation Rotorcrafts, evaluating the influence of offshore turbulence on a helicopter by adopting a helicopter flight mechanics theoretical model, and designing test flight subjects and a test flight method according to an analysis result of the theoretical model; pre-test flight is carried out by using a simulator, a test flight process is verified, so that a test flight risk is controlled, and a complete data processing method is given according to test data in combination with test flight unit evaluation; and a civil helicopter marine lifesaving performance verification subject test flight technology is formed.

Description

technical field [0001] The invention belongs to the technical field of helicopter flight tests, and in particular relates to a flight test method for verifying the life-saving performance at sea of ​​a civilian helicopter. Background technique [0002] The use of helicopters for sea rescue has become more and more important. After an accident at sea, the most important thing is to gain time and rescue the trapped people in the shortest time. Otherwise, the longer the time, the lower the chance of survival. few. Helicopters can be dispatched quickly and reach the destination quickly, and rescue helicopters can flexibly carry out rescue matters according to needs, without being affected by waves, and do not need to leave the port like ships. my country has more than 3 million square kilometers of sea area, more than 6,000 islands, and more than 1,800 kilometers of coastline. The current rescue helicopters and rescue work are far from enough. [0003] Flight test is the most ...
