Předmětem veřejné zakázky je kompletní dodávka systému chlazení zkušebního proudu vzduchu aerodynamického tunelu 3mLSWT. Odůvodnění veřejné zakázky a) Popis potřeb, které mají být splněním veřejné zakázky naplněny: Mezi nejdůležitější součásti výzkumné infrastruktury VZLÚ, a. s. patří nízkorychlostní aerodynamický tunel 3mLSWT s měřicím příslušenstvím. Jedná se o tunel nízkých rychlostí s měřicí sekcí 3 m. Tunel se využívá pro aerodynamický výzkum, např. výzkum laminárního proudění, výzkum řízení odtržení, výzkum vlivu námrazy, podpora vývoje výpočetních metod aj. Při aplikovaném výzkumu a vývoji se tunel využívá pro měření modelů letadel a jejich částí, měření modelů kolejových a silničních vozidel, s dynamometrem pro měření vrtulí, zkoušky větrných elektráren, zkoušky nejrůznějších výrobků na odolnost proti zatížení větrem (antény, stany, prvky fasád, apod.), jako podpora vrcholových sportovců (cyklisté, sáňkaři, apod.), pro stanovení okrajových podmínek pro výpočty CFD atd. Cílem veřejné zakázky je instalace chladícího systému do proudovodu aerodynamického tunelu za účelem stabilizace teploty měřícího proudu vzduchu. Instalací systému chlazení dojde k výraznému potlačení růstu teploty v měřicím prostoru během dlouhého měřicího běhu, čímž se téměř eliminují problémy s teplotními kompenzacemi měřicích zařízení a přístrojů, což usnadní zpracování a vyhodnocení výsledků a usnadní montáže v měřicím prostoru tunelu a dále umožní dosažení vyššího Reynoldsova čísla pro měření. b) Popis předmětu veřejné zakázky: Předmětem veřejné zakázky je kompletní dodávka systému chlazení zkušebního proudu vzduchu aerodynamického tunelu 3mLSWT. Zakázka obsahuje návrh chladícího systému, projektovou dokumentaci, dodávku a instalaci prvků chladícího systému, dodávku a instalaci vyjímatelného chladiče do proudovodu aerodynamického tunelu včetně konstrukčních prvků upevnění a dodávku a instalaci řídící elektroniky zakončené uvedením do provozu. Rozhranní zakázky je definováno napájecím transformátorem a zástavbovými podmínkami v proudovodu aerodynamického tunelu. c) Popis vzájemného vztahu předmětu veřejné zakázky a potřeb zadavatele: Veřejná zakázka je nezbytně nutná k zajištění vědecko-výzkumných činností. d) Předpokládaný termín splnění veřejné zakázky: 4Q 2015

Výzkumný a zkušební letecký ústav, a.s. | Published November 1, 2013

The subject of the public contract is a complete supply of cooling air flow test wind tunnel 3mLSWT. Justification procurement a) Description needs to be compliance with public procurement achieved: The most important part of the research infrastructure VZLÚ, as are low-speed wind tunnel with 3mLSWT test accessories. This is a low-speed tunnel with a test section 3 m tunnel is used for aerodynamic research, such as research laminar flow separation control research, research on the effect of icing, support the development of computational methods, etc. When applied research and development, the tunnel used for the measurement models aircraft and their parts, the measurement model rail and road vehicles, with a dynamometer to measure the propeller testing wind turbines, testing various products for resistance to wind load (antenna, tents, facade elements, etc.), as support for elite athletes (cyclists, toboggan etc.) to determine the boundary conditions for CFD calculations, etc. The aim of procurement is to install the cooling system to proudovodu wind tunnel to stabilize the temperature measuring air flow. By installing the cooling system will significantly inhibit the growth temperature in the measurement area over a long measurement run, thus almost eliminating problems with temperature compensation measuring equipment and apparatus to facilitate the processing and interpretation of results and facilitate installation of the measuring area of ​​the tunnel and to achieve higher Reynolds numbers measurement. b) Description of Procurement: The procurement is a full supply of cooling air flow test wind tunnel 3mLSWT. Contract includes designing the cooling system, project documentation, delivery and installation of the cooling system, supply and installation of removable cooler to proudovodu wind tunnel design elements including fixing and supply and installation of the control electronics ending commissioning. Interface contract defined power transformer and zástavbovými proudovodu conditions in the wind tunnel. c) Description of the relationship between the subject of the contract and the client's needs: A public contract is necessary to ensure the scientific-research activities. d) Expected date of fulfillment of contracts: 4Q 2015
