    • A wing (1) including a lift augmentation device, comprising a main wing body (3) and a displaceable auxiliary body (5) defining a lift augmenting configuration and a non-augmenting configuration and moveable to intermediate configurations therebetween. A vortex is generated extending spanwise of the wing at the junction between the main wing body and the auxiliary lift-augmenting body, the arrangement being such that the generated vortex rotates in a direction which causes the airflow in the vortex to be co-current with the airflow passing over the wing body at a relatively lower pressure side of the wing body and the flow of the vortex air to be counter current with the over the wing body in the relatively higher pressure region around the wing body.

    • There is disclosed a method of distributing particles in a flow of gas and a needleless syringe for use in the needleless injection of particles into the skin or mucosa of a vertebrate subject. The syringe has the advantage that no bursting membranes are required, reducing noise, and that the particles are substantially uniformly distributed in the gas stream. This is achieved by providing a convergence which reduces pressure of the gas flowing in the gas flow path due to the Venturi effect such that particles initially located outside of the gas flow path are drawn into the gas flow path under the action of the reduced pressure and become entrained in the gas. An exit nozzle is provided to accelerate the particles so entrained. In another aspect of the invention, there is provided a method of creating a gas flow in a needleless syringe which comprises flowing gas through a first convergence into a chamber to form a transsonic gas jet in the chamber and passing the gas jet from the chamber into a second convergence and along the nozzle. This provides an advantageous flow regime suitable for the needleless injection of powders.
    • 公开了一种在气流中分配颗粒的方法和一种无针注射器,用于将颗粒无针注射到脊椎动物受试者的皮肤或粘膜中。 该注射器具有不需要破裂膜的优点,减少了噪音,并且颗粒基本均匀地分布在气流中。 这是通过提供会聚来实现的,该会聚降低了由于文丘里效应而在气体流动路径中流动的气体的压力,使得初始位于气体流动路径外部的颗粒在减压的作用下被吸入气体流动路径中,并且 成为气体中的夹带物。 提供出口喷嘴以加速夹带的颗粒。 在本发明的另一方面中,提供了一种在无针注射器中产生气流的方法,该方法包括使气体通过第一会聚物流入腔室中以在腔室中形成转换气流并使气体射流从腔室流入 第二次会聚并沿着喷嘴。 这提供了适合于无针注射粉末的有利流动状态。
