Advanced Landing Gear Aero-loads and Aero-noise Prediction (ALGAAP)

该项目有两个主要活动，其共同目标是为起落架和舱门提供高精度的气动载荷和噪声预测。第一项活动将开发和测试1/10比例的飞机模型，包括主起落架和前起落架的详细模型。起落架模型包括活动门、起落架、转向架和转向架。载荷数据是使用安装在模型组件上的微型测压元件以及压力胶带采集的。第二项活动将集中于开发高精度计算流体动力学起落架气动载荷和噪声预测方法，这些方法使用以前用于噪声预测的非定常CDF代码。这些模型将通过包括PIV测试在内的各种风洞测试进行验证。验证这些CFD模型对风洞试验数据是该项目的目标。

There are two principal activities in this project, related by the common objective of providing high-precision, aero-loads and noise predicition for landing gear and doors. The first activity will develop and test a 1/10th scale aircraft model including detailed models of main and nose landing gears. The landing gear models include movable doors, landing gear, steering and bogies. Loads data is captured using miniature load cells mounted on the model components in addition to pressure tapings. The second activity will focus on the development of high precision CFD landing-gear aero-loads and noise-prediction methods using non-steady CDF codes used previously for noise prediction. These models will be validated against a variety of wind tunnel tests including PIV testing. Validation of these CFD models against wind-tunnel test data is the objective of the project.
