Analysis of the wind tunnel test of a tilt rotor power force model [PDF]
Two series of wind tunnel tests were made to determine performance, stability and control, and rotor wake interaction on the airframe, using a one-tenth scale powered force model of a tilt rotor aircraft.

A flight dynamics investigation of compound helicopter configurations [PDF]
, 2013 Compounding has often been proposed as a method to increase the maximum speed of the helicopter. There are two common types of compounding known as wing and thrust compounding.

Allergy, EarlyView.This study established a microarray containing a representative panel of purified Blo t and Der p allergens for the identification of patients sensitised to Blo t and/or Der p. Results indicate that the microarray based on Blo t and Der p allergens is a useful tool for the identification of Blo t‐ and/or Der p‐sensitised patients. The microarray may be

Damage and Failure of Aeroengine Blades Under Small UAV Impacts
International Journal of Aerospace EngineeringUnmanned aerial vehicles (UAVs) may collide with vulnerable parts of other aircrafts, such as engine blades, causing accidents. The research on small UAV impact is limited. Besides, UAV impact with propeller and rotor blades is poorly understood. In this

An investigation of rotor harmonic noise by the use of small scale wind tunnel models [PDF]
Noise measurements of small scale helicopter rotor models were compared with noise measurements of full scale helicopters to determine what information about the full scale helicopters could be derived from noise measurements of small scale helicopter ...

Investigation of a Compound Helicopter Flying the Depart and Abort Mission Task Element [PDF]
, 2017 The next generation of rotorcraft will have to satisfy the appropriate handling qualities requirements before entering service. Many of these vehicles will operate at significantly greater speeds than the conventional helicopter and will therefore have

British Journal of Pharmacology, EarlyView.Abstract Background and Purpose Guanylate cyclase‐C (GC‐C) is the receptor for endogenous (uro)guanylin peptides, bacterial toxins and pharmacological analogues. Receptor activation leads to intestinal fluid loss, but also activates an antiproliferative pathway and is a promising target in colorectal cancer therapy.
