The workplace of Naval examine (ONR) shrunk with the Naval reviews Board (NSB) of the nationwide study Council (NRC) to set up a committee to study ONR's plane expertise application (ATP). The committee convened on could 15 and sixteen, 2001, and reviewed a few 28 technology and expertise (S&T) efforts that have been awarded as constituting the ATP. The committee met individually on could 17, 2001, to formulate its findings and suggestions. This record represents the consensus opinion of the committee and relies at the info awarded on the evaluation. The ONR ATP is living in the Strike know-how department (Code 351) of the Naval Expeditionary struggle technological know-how and know-how division (Code 35). In 2001 the ATP is funded at $55.0 million, that's nearly 60 percentage of the Strike know-how department finances. The ATP S&T 2001 finances is additional divided into the subsequent different types: (1) 6.1 easy learn at $4.3 million, (2) 6.2 exploratory improvement at $18.1 million, and (3) 6.3 complicated improvement, together with know-how demonstrations, at $32.5 million. although, the ATP may be in significant transition starting in FY02.

Starting in FY02, all the 6.3 investment and one-half of the 6.2 investment on the ONR could be devoted to 12 significant software parts known as destiny Naval features (FNCs). the aim of the FNCs is to concentration complicated expertise improvement at ONR on naval strength features which were pointed out as excessive precedence for the longer term by way of a cross-functional crew of naval operators, naval improvement and aid organisations, and ONR application managers. Plans were made to combine numerous of the Code 351 courses reviewed into FNCs. The ATP used to be provided to the committee in six thrust parts: built-in avionics, propulsion and gear, air car know-how, unmanned aerial vehicles/unmanned wrestle air autos (UAVs/UCAVs), survivability, and certain aviation tasks. a number of initiatives have been offered inside of every one thrust zone. The committee prepared this file based on those thrust components, and in numerous of those parts it additionally indicates new S&T subject matters for attention for the long run ATP. The findings and proposals of the committee are summarized during this report.

David Baker's NASA Space Shuttle Manual : An Insight into the Design, PDF

Designed among 1969 and 1972 and primary flown into area in 1981, the NASA travel could have flown virtually a hundred and forty missions by the point it's retired in 2010. David Baker describes the starting place of the reusable release automobile inspiration throughout the Sixties, its evolution right into a attainable flying computing device within the early Seventies, and its next layout, engineering, development and operation.

Example text

In the FACIA project, the heavily loaded composite control surface hinge and fittings appear to be a unique technology application that warrants continued pursuit. It was unclear what types of failure modes are being evaluated in the MUST project, whether micromechanical considerations are included, or how the life of the engineered failure mode will be quantified and used to derive field-level inspection strategies and metrics. The corrosion-assisted fatigue project directly addresses reduction of operational costs of legacy systems by managing corrosion.

This is definitely a success-oriented plan and as such will probably not be completed this year. ONR has requested another $300,000 to perform post-ATD flight demonstrations in FY02. Assuming success of the flight tests, the challenge remaining is to transition the CRW concept into future Navy UAV/UCAV designs or perhaps to position it as a candidate future upgrade for the Navy’s helicopter-like vertical takeoff and landing tactical uninhabited aerial vehicle (VTUAV) (planned as the Pioneer replacement), currently under contract for engineering and manufacturing development.

This project will also determine procedures for quantifying corrosion rates. The SLAE program has successfully transitioned the technology of bonded composite patches for repair of primary airframe structures. Demonstrated on the F-5 vertical stabilizer, use of bonded composite patches showed a 75:1 savings compared with full removal and replacement and a 20:1 savings compared with complete reskinning. Findings Bonded composite patches were originally intended for temporary repair but have now been certified for permanent use.
