An alternative approach to induced drag reduction
Aviation, 2021 Induced drag constitutes approximately 40% of the total drag of subsonic civil transport aircraft at cruise conditions. Various types of winglets and several non-planar concepts, such as the C-wing, the joined wings, and the box plane, have been proposed

KINEMATICS OF A MECHANISM WITH STOPPINGS, BASED ON A HYPOCYCLOID WITH 6 BRANCHES [PDF]
Fiabilitate şi Durabilitate, 2010 They are studied the positions, velocities and accelerations of a mechanism based on planetary gear and a RRP dyad. The mechanism ensures the plunger stop on a certain subinterval of the cycle, although the leading element is rotating.

Epihypocurves and epihypocyclic surfaces with arbitrary base curve
Structural Mechanics of Engineering Constructions and Buildings, 2021 If a circle rolls around another motionless circle then a point bind with the rolling circle forms a curve. It is called epicycloid, if a circle is rolling outside the motionless circle; it is called hypocycloid if the circle is rolling inside the ...

Metrizamide cisternography with hypocycloidal tomography: preliminary results [PDF]
American Journal of Roentgenology, 1976 Metrizamide (Amipaque), a nonionic water soluble contrast agent, has been shown to be safe and efficacious for lumbar myelography. Clinical trials of cervical, thoracic, and even intracranial examinations have produced good results. Despite an inherent neurotoxicity, significant complications have been quite rare, and patient tolerance in general is ...

CALCULATION OF SMOOTHING-DOWN ABILITY OF DISK MACHINES
Наука и техника, 2006 The method for calculation of circle, epi- and hypocycloid length makes it possible to obtain values of smoothing-down ability of disk working elements with rotary and planetary motion. Calculation of smoothing-down ability of a planetary working element

RESEARCH ON STRESS AND STRENGTH OF WO-STAGE CYCLOID BALL PLANETARY TRANSMISSION
Jixie qiangdu, 2016 The mechanical model of meshing pair was built. Force of two meshing pairs and turning arm bearing were analysed. The contact stress of hypocycloid and epicycloid tooth surface was deduced with Hertz theory.

Geometric design and dynamic characteristics of a novel abnormal cycloidal gear reducer
Advances in Mechanical Engineering, 2023 A precision reducer with a high ratio and a small size is essential for precise control of the position of a robotic arm. The rotate vector (RV) is a reducer widely applied in robotic joints. However, its complex structure, over-positioning and difficult
