The aerodynamic design of rotor blades is challenging, and is crucial for the development of helicopter technology. Previous aerodynamic optimizations that focused only on limited design points find it difficult to balance flight performance across the en... see more

This paper describes the experiment for learning and investigation of the helicopter laboratory model static and dynamic characteristics. Helicopter model is not the free flying one, as it has the two degrees of freedom â?? up / down movement and rotation... see more

Tujuan penelitian untuk memperoleh gambaran tentang hubungan antara kondisi sosial ekonomi keluarga dengan helicopter parenting. Kondisi sosial ekonomi pada artikel ini antara lain: pendidikan, pekerjaan, dan pendapatan. Metode penelitian menggunakan meto... see more

The object of research is a set of screen-exhaust devices (SED) as part of the Mi-8MSB-V helicopter (Ukrainian version of the modernization of the Soviet multipurpose Mi-8 helicopter, developed by Motor Sich JSC, Zaporizhzhia, Ukraine). The SED set is des... see more

The helicopters used for marine operations encounter harsh environment laden with salt mist, sand and dust which could accelerate the deterioration of components. Assessment of the effect of operational environment on component degradation of such helicop... see more

The experimental data for a Cbladed soft-inplane hingeless main rotor is used to validate a comprehensive aeroelastic analysis. A finite element model has been developed for the rotorblade which predicts rotating frequencies quite well, across a range of ... see more

Aerodynamic noise includes a number of noise components, among which rotational noise and vortex noise (BVI-noise) make the largest contribution to the overall noise generated. Rotation noise depends on the magnitude of the velocity of the incoming blade ... see more

Con este trabajo se busca demostrar que El extraño de Orson Welles, una obra denostada por el propio director, al considerarla un mero producto comercial, se trata, sin embargo, de una de sus producciones ideológicamente más ambiciosas. A partir de los es... see more
