As small rotorcraft grow in capability, the possibilities for their application increase dramatically. Many of these new applications require stable outdoor flight, necessitating a closer look at the aerodynamic response of the aircraft in windy environments. This paper develops the equations of motion for a single-propeller test stand by analyzing the blade-flapping response of a small-stiff p...

AIM: To describe the subcutaneous pedicled propeller flap technique for microscopic reconstruction of eyelid defects and evaluate its outcomes. METHODS: The clinical data 23 patients (23 eyes) who underwent with were retrospectively analyzed. All tumor resection one-stage anterior- or posterior-layer defects. survival rate flap, function appearance, recurrence rate, patient satisfaction evaluat...

Abstract Background To cover soft tissue defects, the perforator-based propeller flap offers option to rotate healthy into complex wounds. By rotating flap, perforator is torqued. As a result, perfusion changes are possible. Methods A retrospective data analysis of patients was done, who received defects lower extremity as well peri- and postoperative monitoring with laser-Doppler-spectrophotom...

Partial breast reconstruction using perforator flaps harvested from the lateral chest wall has become a well-established surgical technique recently. In the case of a partial mastectomy with an axillary lymph node dissection, there are 2 main defects; one is a partial breast defect and the other is an axillary dead space. To reconstruct the 2 separate defects with local flaps, basically 2 diffe...

this paper presents numerical calculations for podded propulsion system using vortex theory and potential panel method. the method discretizes the surface boundary of the body (propeller +pod+strut) and obtained the vortex and propeller surface and potential on strut and pod. a model propeller and strut are considered for these calculations and the results of pressure distribution, flow field a...
