This paper characterises the power consumption of electric rotorcraft and derives an endurance estimation model for such aircraft powered by LiPo batteries. Theoretical analysis is backed by experimental flight tests using a popular commercial quadrotor. Experiments on Commercial Off-The-Shelf Lithium-Polymer batteries, which are the technology dominating(More)
Slipped capital femoral epiphysis may be associated with hypothyroidism and other endocrinopathies. Routine screening for such abnormalities is unlikely to be cost-effective since the overall incidence of these disorders, in association with slipped capital femoral epiphysis, is low.
