As an aircraft changes speed or altitude, the pressure of the air at the inlet to the compressor will vary. Le terme « compresseur centrifuge » (aussi appelé « compresseur radial ») désigne un type de turbomachines à circulation radiale et à absorption de travail qui comprend des pompes, des ventilateurs, des soufflantes et des compresseurs1. All compressors have a sweet spot relating rotational speed and pressure, with higher compressions requiring higher speeds. Their big weight, combined with their high starting power requirements are some of their drawbacks. Early engines were designed for simplicity, and used a single large compressor spinning at a single speed. integrally intercooled axial compressor and its application to power plants: compresseur axial à refroidissement intermédiaire intégral et son utilisation dans les centrales électriques: As in this investigation, damage was observed on 1 of the axial compressor blades (Photo 5).

See if you can get into the grid Hall of Fame ! Axial compressors have relatively high peak efficiency. 'Mechanics and Thermodynamics of Propulsion,' 2nd edn, Prentice Hall, 1991. The axial compressor has a two-stage guide-blade cascade (8) at the outlet-side end (5) of the rotor (4). Get XML access to fix the meaning of your metadata. Treatment. Bleed systems were already commonly used anyway, to provide airflow into the turbine stage where it was used to cool the turbine blades, as well as provide pressurized air for the air conditioning systems inside the aircraft. A compressor in which the fluid enters and leaves in the axial direction is called axial flow compressor. translation and definition "axial compressor", English-French Dictionary online. A velocity diagram shows the relative velocities of the blade rows and the fluid. Axial compressors consist of rotating and stationary components. This was also used to help start the engine, allowing it to be spun up without compressing much air by bleeding off as much as possible. Axial-flow compressor definition: a device for compressing a gas by accelerating it tangentially by means of bladed rotors... | Meaning, pronunciation, translations and examples An animation of an axial compressor. axial compressor . Le compresseur axial génère un flux continu d'air comprimé [4] et fournit un rendement élevé pour une masse volumique donnée et une section donnée du compresseur. De très nombreux exemples de phrases traduites contenant "axial compressor" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. Axial compressors are rotating, airfoil-based compressors in which the working fluid principally flows parallel to the axis of rotation.

Se dit d'une ligne de transmission constituée de deux conducteurs circulaires concentriques, séparés par un diélectrique le plus souvent en polyéthylène. Research Assistant – Axial Compressors Aerodynamics Application Deadline: 03/11/2020 23:59 - Europe/Brussels Contact Details. The only obvious effort was a test-bed compressor built by Hayne Constant, Griffith's colleague at the Royal Aircraft Establishment. Give contextual explanation and translation from your sites ! This condition, known as surging, was a major problem on early engines and often led to the turbine or compressor breaking and shedding blades. In England, Hayne Constant reached an agreement with the steam turbine company Metropolitan-Vickers (Metrovick) in 1937, starting their turboprop effort based on the Griffith design in 1938.
