Effectiveness of the Compound Helicopter Configuration in Rotorcraft Performance Increase
transactions on aerospace research 4(261) 2020, pp.81-106 DOI: 10.2478/tar-2020-0023 eISSN 2545-2835 effectiveness of the compound helicopter configuration in rotorcraft performance increase Jarosław stanisławski Retired doctor of technical sciences [email protected] • ORCID: 0000-0003-1629-4632 abstract The article presents the results of calculations applied to compare flight envelopes of varying helicopter configurations. Performance of conventional helicopter with the main and tail rotors, in the case of compound helicopter, can be improved by applying wings and pusher propellers which generate an additional lift and horizontal thrust. The simplified model of a helicopter structure, consisting of a stiff fuselage and the main rotor treated as a stiff disk, is applied for evaluation of the rotorcraft performance and the required range of control system deflections. The more detailed model of deformable main rotor blades, applying the Galerkin method, is used to calculate rotor loads and blade deformations in defined flight states. The calculations of simulated flight states are performed considering data of a hypothetical medium class helicopter with the take-off mass of 6,000kg. In the case of both of the helicopter configurations, the articulated main rotor hub is taken under consideration. According to the Galerkin method, the elastic blade model allows to compute blade deformations as a combination of the blade bending and torsional eigen modes. Introduction of additional wing and pusher propellers allows to increase the range of operational speed over 300 km/h. Results of the simulation are presented as time- runs of rotor loads and blade deformations and in a form of disk distribution plots of rotor parameters. -

We aimed to study the availability, perception, and future aspects of POCUS in the European HEMS. Methods: A survey about the use of POCUS in HEMS was conducted by a multinational steering expert committee and was carried out from November 30, 2020 to December 30, 2020 via an online web portal. Invitations for participation were sent via email to the medical directors of the European HEMS organizations including two reminders. Results: During the study period, 69 participants from 25 countries and 41 different HEMS providers took part in the survey. -

This article is published with open access at Springerlink.com Abstract Assessment of risk considering both the probability of occurrence of a natural phenomenon and its consequences on the elements at risk is an essential step before the design of adequate risk reduction strategies in local, regional or national level. Within the EU-funded project SEERISK ‘‘Joint disaster management risk assessment and prepared- ness for the Danube macro-region’’, a common methodology for risk assessment and mapping for climate change-related hazards has been developed. Vulnerability assessment is a large part of the risk assessment procedure, and it requires a considerable amount of detailed data. The methodology for risk assessment presented here is in line with the EC Guidelines for Risk Assessment and Mapping, and it provides alternatives in order to tackle the problem of varying data quality and quantity necessary for the analysis of hazard and vulnerability. In the present study, the methodology is adapted for heat waves and is applied in the city of Arad, Romania. -

The crash initiated panic within UK Oil and Gas industry, demanding grounding of the Super Puma fleet of helicopters. Four people died when the CHC Super Puma crashed on approach to Sumburgh Airport on 23 August 2013. 1 All Super Puma helicopter passenger flights to UK oil installations were suspended after a crash off Shetland claimed the lives of four people. The Helicopter Safety Steering Group (HSSG) had advised grounding all variants of the helicopter. The HSSG, which is made up of oil industry representatives, advised that all models of the Super Puma series including: AS332 L, L1, L2 and EC225 should be grounded for "all Super Puma commercial passenger flights to and from offshore oil and gas installations within the UK." The Norwegian civil aviation authority had earlier rejected appeals from its unions to ground all its Super Pumas – which operate in the North Sea in very similar weather conditions to the UK fleet – insisting that Friday's crash was an isolated incident.
