PANDORA

Deutsches Zentrum für Luft- und Raumfahrt e.V. (DLR)

The objective of this activity is to carry out the detailed design and manufacturing of a subassembly for the EU-Horizon 2050 funded project PANDORA (OPEN FAN VALIDATION FOR CARBON-FREE AIRCRAFTS | PANDORA | Projekt | Informationsblatt | HORIZON | CORDIS | Europäische Kommission) Open Fan Wind Tunnel Mode Test Article, whose preliminary design has been carried out by the PANDORA consortium. The status of the design is deemed to be mature enough to proceed to the detailed design phase. The preliminary aerodynamic shape of the rotor is frozen but during the detailed design phase interactions with the subcontractor are expected to ease the detailed mechanical design alleviating stress concentration in selected features of the rotor to maximise rotor life. The rig is expected to operate in two different facilities. The first installation is a low-speed wind tunnel operating at atmospheric conditions. Maximum Mach number is expected to be around 0.25. The second facility is a high-speed wind tunnel opera ng at sub-ambient conditions and a maximum Mach number of around 0.8 The expected outer and inner radii of the rotor are approximately 300 mm and 100 mm, respectively, and thus the blade height is approximately 200 mm. The number of rotor blades has been fixed to 12. The es mated maximum speed is about 7,700 rpm. The rotor is expected to feature a variable pitch mechanism that will be manually actuated at rest. The subcontractor, as responsible of all the rotating parts, will also design and manufacture a device to measure the pitch setting of all the blades before the rig opera on. The contractor will not use Level 2 subcontractors for critical components (most notably the Rotating Sha Balance), but will only utilize subcontractors for small parts or accessories. In the event of any doubts, the contractor will submit proposals in the ROM. DLR will request on-site support to operate the Rotating Shaft Balance during three weeks of testing. In summary, the objective of this contract is to carry out the detailed design of an open rotor prototype, its manufacturing, and the development and integration of a system that allows for the measurement of the three components of rotor forces and moments, namely a Roating Shaft Balance (RSB). The deliverables will include the hardware, analysis models, and a CAD representation of the prototype.

Verfahren zur Überprüfung
Genaue Informationen über Fristen für Überprüfungsverfahren:

An application for review is only admissible if - the applicant has notified the contracting authority within 10 calendar days of becoming aware of any breaches of procurement regulations recognised by it in the procurement procedure, - the applicant has notified the contracting authority of violations of procurement regulations that are recognisable on the basis of the contract notice no later than the expiry of the deadline for applications specified in the contract notice, - the applicant has notified the contracting authority of any infringements recognisable in the tender documents by the expiry of the deadline for submission of tenders at the latest, - no more than 15 calendar days have elapsed since receipt of the contracting authority's notification that it does not intend to remedy a complaint. An application for review is inadmissible if more than 15 calendar days have elapsed since receipt of the notification from the contracting authority that it does not intend to remedy a complaint (Section 160 (3) sentence 1 no. 4 GWB). An application for review is also inadmissible if the contract has been awarded before the awarding chamber has informed the contracting authority of the application for review (sections 168 (2) sentence 1, 169 (1) GWB). The contract may be awarded 15 calendar days after the bidder information has been sent in accordance with Section 134 (1) GWB. If the information is sent electronically or by fax, the deadline is reduced to 10 calendar days (Section 134 (2) GWB). The period begins on the day after the information is sent by the contracting authority; the day of receipt by the bidder and candidate concerned is irrelevant. The admissibility of an application for review also requires that the alleged breaches of procurement regulations have been notified within 10 calendar days of becoming known (Section 160 (3) sentence 1 no. 1 GWB). Violations of procurement regulations that are recognisable on the basis of the contract notice must be notified to the contracting authority no later than the expiry of the deadline for application or submission of tenders specified in the contract notice (Section 160 (3) sentence 1 no. 2 GWB). Violations of procurement regulations that are only recognisable in the tender documents must be reported to the contracting authority by the expiry of the deadline for submitting applications or tenders at the latest (Section 160 (3) sentence 1 no. 3 GWB). Please note that only the German version of the application requirements is legally binding.
