This paper states evaluative methods of technology readiness which are used in the national background projects development. The methods conduct helicopter transmission system technology maturity research and assessment of native significant project according to methods of technology readiness assessment. The conclusions indicate that methods of technology readiness assessment have very important promoting action to native project development and scientific decision-making. The project which adopts mature critical technology implies that guarantee the schedule of project development and reduce risk of project development. Actualizing assess methods of technology readiness can be an important part of project development risk management.

Purpose This paper aims to establish a prediction model of stable transmission time of spiral bevel gear during a loss-of-lubrication event in helicopter transmission system. Design/methodology/approach To observe the temperature change of spiral bevel gear during working condition, a test rig of spiral bevel gear was developed according to the requirements of experiments and carried out verification experiments. Findings The prediction is verified by the test of detecting the temperature of oil pool. The main damage form of helicopter spiral bevel gears under starved lubrication is tooth surface burn. The stable running time under oil-free lubrication is mainly determined by the degree of tooth surface burn control. Originality/value The experimental data of the spiral bevel gear oil-free lubrication process are basically consistent with the simulation prediction results. The results lay a foundation for the working life design of spiral bevel gear in helicopter transmission system under starved lubrication.

Technology Readiness Levels (TRL) are a framework, originally created by NASA and later adopted and tailored by the US Department of Defense (Graettinger, Garcia, Siviy, Schenk, Van Syckle, 2002) to track the progress and maturity of a given technology. There are a number of derivative readiness level frameworks that have spun off the original TRL framework such as System Readiness Levels, Software Readiness Levels, Integration Readiness Levels, and Manufacturing Readiness Levels, just to name a few. Most of the time, these frameworks have an associated readiness assessment used to identify or assess the precise readiness level status. Human Readiness Levels (HRLs) are a framework used to identify the level of readiness or maturity of a given technology as it relates to its usability and its refinement to be used by a human(s) (Phillips, 2010). There are a number of HRL frameworks or similar (e.g. Human Factors Readiness Levels), yet little attention has been paid to Human Readiness Assessments (HRAs). The purpose of this paper is to review the literature of Human Readiness Levels and introduce a new multivariate Human Readiness Assessment that emphasizes workload, situation awareness (SA), and usability.
