Technology needs for high speed rotorcraft (3)

The spectrum of vertical takeoff and landing (VTOL) type aircraft is examined to determine which aircraft are most likely to achieve high subsonic cruise speeds and have hover qualities similar to a helicopter. Two civil mission profiles are considered: a 600-n.mi. mission for a 15- and a 30-passenger payload. Applying current technology, only the 15- and 30-passenger tiltfold aircraft are capable of attaining the 450-knot design goal. The two tiltfold aircraft at 450 knots and a 30-passenger tiltrotor at 375 knots were further developed for the Task II technology analysis. A program called High-Speed Total Envelope Proprotor (HI-STEP) is recommended to meet several of these issues based on the tiltrotor concept. A program called Tiltfold System (TFS) is recommended based on the tiltrotor concept. A task is identified to resolve the best design speed from productivity and demand considerations based on the technology that emerges from the recommended programs. HI-STEP's goals are to investigate propulsive efficiency, maneuver loads, and aeroelastic stability. Programs currently in progress that may meet the other technology needs include the Integrated High Performance Turbine Engine Technology (IHPTET) (NASA Lewis) and the Advanced Structural Concepts Program funded through NASA Langley

ECONOMIC IMPACTS OF REGULATIONS TO PRESERVE NATIVE WOODLAND ON PRIVATE PROPERTY: A CASE STUDY IN THE HUNTER VALLEY OF NEW SOUTH WALES

Australian policies to preserve native vegetation on farms rest on mandatory regulations without compensation, whereas policies in most OECD countries rest on voluntary conservation with compensation. In New South Wales, the Native Vegetation Conservation Act 1998 restricts farmers from clearing native vegetation on their own freehold land, and offers no compensation. The Act may therefore impose opportunity costs, or losses in income, on landholders. These opportunity costs are estimated for a case study property in the Hunter Valley of New South Wales, and these results are then generalised to assess the broad trade-offs between development and preservation. The losses in income appear to vary between 5 and 10 per cent of annual income, depending on livestock prices. The flow of these losses over time appears to total some $26m for all properties of this kind in the immediate region. In addition to imposition of these direct opportunity costs, the regulations hinder land sales and so hinder adjustment by landholders to changing conditions.Native vegetation, environmental preservation, opportunity cost., Land Economics/Use,
