Abstract

Hava hızı; karasal, deniz, uzay ve havacılıktaki pek çok uygulamalarda kritik öneme sahip bir parametredir. Özellikle uçaklarda bu parametrenin hesaplanması ile türbülans, rüzgâr kesmesi gibi olaylar önceden tahmin edilebilir ve buna yönelik önlem alınabilir. Hava hızının ölçümünde kullanılan geleneksel ve lazer tabanlı teknikleri, çalışma detayları ile örnek sistem tasarımları araştırılmıştır. Ayrıca Light Detection and Ranging (LIDAR) teknolojisinin bu teknikler içerisinde edindiği yer çalışmamızda incelenmiştir. Ek olarak, hava hızı ölçümünde önemli üstünlükleri olan UV Doppler LIDAR’ın, avantajları ve tasarım karakteristikleri araştırılmıştır.

Investigation of Laser Based Air Speed Measurement Methods

Abstract

Airspeed is a critical parameter in many applications in terrestrial, marine, space, and aviation. Especially in airplanes, by calculating this parameter, events such as turbulence and wind shear can be predicted, and precautions can be taken. In this study, traditional and laser-based techniques used in the measurement of air velocity, working details and sample system designs were investigated. In addition, the importance of Light Detection and Ranging (LIDAR) technology in these techniques has been examined. In addition, the advantages and design characteristics of UV Doppler LIDAR, which has significant advantages in air velocity measurement, are investigated.
