Influences of propeller advance ratio on delta-winged uav model vortex properties by Ramalingam, Santhoshinii, Mat, Shabudin, Kasim, Khushairi Amri, Said, Mazuriah, Mohd. Nasir, Mohd. Nazri, Nik Mohd., Nik Ahmad Ridhwan, Mansor, Shuhaimi, Mohamed Radzi, Nor Haizan, Perumal, Kannan

“…The results from the surface pressure measurement have showed that the propeller advance ratio influences the development of the primary vortex above the delta-winged model. …”

Propeller locations study of a generic delta wing UAV model by Kasim, Khushairi Amri, Mat, Shabudin, Ishak, Iskandar Shah, Mansor, Shuhaimi

“…Originality/value: To the best of the author’s knowledge, the surface pressure data available for a non-slender delta-shaped UAV model is limited. …”

Reynolds number effects on flow topology above blunt-edge delta wing VFE-2 configurations by Said, Mazuriah, Mat, Shabudin, Mansor, Shuhaimi, Abdul Latif, Ainullotfi, Mat Lazim, Tholudin

“…Two measurement techniques were employed on the models i.e. steady force balance and surface pressure data. The current experiments showed that an increase in leading edge bluntness and Reynolds number can delay the formation of the primary vortex towards the aft portions of the wing.…”

Wind tunnel experiments on a generic sharp-edge delta wing UAV model by Mohd. Zain, Nadhirah, Mat, Shabudin, Kasim, Khushairi Amri, Mansor, Shuhaimi, Dahalan, Md. Nizam, Othman, Norazila

“…During the experiments, two measurement techniques were employed; steady forces and surface pressure measurements. The experimental data highlights an impact of propeller size on the coefficients of lift, drag, and moment and vortex system of the delta-shaped UAV. …”

Experimental investigation on blunt-edged UTM delta wing VFE-2 configurations at low reynolds number by Daman Huri, Muhammad Zal Aminullah, Mat, Shabudin, Said, Mazuriah, Mansor, Shuhaimi, Dahalan, Md. Nizam, Abdul-Latif, Ainullotfi

“…Two measurement techniques were employed on the upper surface of the wing, i.e. experimental surface pressure and tuft techniques. Experiments were also conducted on two different leading edge profiles namely medium and large radius profiles with different leading edge radius-to-wing chord ratio. …”

Wind tunnel experiment of UTM-LST generic light aircraft model with external store by Abdul Manaf, Muhammad Zaki, Mat, Shabudin, Mansor, Shuhaimi, Nasir, Mohd. Nazri, Mat Lazim, Tholudin, Wan Ali, Wan Khairuddin, Wan Omar, Wan Zaidi, Mohd. Ali, Zurriati, Abdul-Latif, Ainullotfi, Abd. Wahid, Mastura, Dahalan, Md. Nizam, Othman, Norazila

“…An interesting feature observed from surface pressure studies where, the results showed that the pressure coefficient increased when the external is mounted on the wing at a low angle of attack. …”
