SBC: MAINSTREAM ENGINEERING CORP Topic: N10AT037
In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposes to use a passive, permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat gen ...STTR Phase I 2010 Department of DefenseNavy
SBC: JM HARWOOD, LLC Topic: N10AT033
JM Harwood, LLC, and UAH Propulsion Research Center propose the development of an electronic miniature Direct Fuel Injection (DFI) system for 5-20 hp heavy fuel engines. This highly integrated Very Small Injection Technology (V-SInTech) DFI system will be capable of (a) multiple injections per cycle, (b) variable injection timing, (c) variable spray penetration depth, (d) real-time closed loop mod ...STTR Phase I 2010 Department of DefenseNavy
SBC: SOAR TECHNOLOGY INC Topic: N10AT040
We will demonstrate the feasibility of detecting tactically meaningful complex events in sensor input streams using an efficient pattern matching technology embodied in the Soar cognitive architecture. Our focus in Phase I will be on video streams, such as those that might be produced by unattended ground sensors or unmanned aerial systems. To reduce risk, we propose devoting a portion of our effo ...STTR Phase I 2010 Department of DefenseNavy
SBC: UES INC Topic: N10AT028
Thermo-mechanical processes of turbine disks have been progressively improved to meet microstructural requirements tailored for advanced, sustainable high temperature performances. However, the chemistry of typical Ni-base turbine disk alloys is very complex, and yields a variety of phases and microstructural anomalies under different thermo-mechanical heat treatments. These microstructural hetero ...STTR Phase I 2010 Department of DefenseNavy
A Fast-Response, Electronically Controlled Fuel Injection System for Small Heavy Fuel Engines with Multi-Fuel CapabilitiesSBC: MAINSTREAM ENGINEERING CORP Topic: N10AT033
Advances in electronically controlled injection technologies for diesel engines have provided a method to improve medium- to heavy-duty engine performance through increased injection pressures, multiple injections, and injection rate shaping. Although these injection systems have been primarily limited to larger engines, the ability to rapidly and precisely meter fuel for smaller engines is partic ...STTR Phase I 2010 Department of DefenseNavy
SBC: N&R ENGNERING MGT SUPPORT SVCS Topic: N10AT010
The Phase I deliverable will be a physic-based model which represents a CMC gas turbine component concomitantly at the material level and the structural level. This model will be probabilistically analyzed to account for the uncertainties in material properties and the uncertainties in the size and impact velocities of possible foreign objects (FOD). A ceramic material must display sufficient capa ...STTR Phase I 2010 Department of DefenseNavy
SBC: BUSA Engineering Consulting Topic: N10AT002
This proposal is being submitted in response to the solicitation topic N10A-T002 (Development of a Computational Method for Prediction of After Burning Effect) by BUSA Engineering Consulting (Dr. Jianghui Chao) in collaboration with University of Florida (PI: Prof. S. Balachandar). The overall objective of the proposed effort is to contribute to national defense and security by advancing the state ...STTR Phase I 2010 Department of DefenseNavy
Advanced Materials for the Design of Lightweight JP5/JP8/DS2 Fueled Engines for Unmanned Aerial Vehicles (UAVs)SBC: Northwest Uld, Inc. Topic: N10AT001
Northwest UAV Propulsion Systems proposes using our purpose built heavy fuel engine designed and built in the USA for small unmanned aerial systems in the tier 2 & 3 class. We will be adding a lightweight ceramic material set combined with FEA (Finite Element Analysis) and heavy fuel atomizer (IRAD Project) to create a lightweight engine for a SUAS or STUAS class UAVs. The Ceramic material set is ...STTR Phase I 2010 Department of DefenseNavy
Development of Surface Reaction Mechanism for C-SiC-SiO2-Rubber Composite Oxidation in Extreme Oxidizing ConditionSBC: CFD RESEARCH CORPORATION Topic: N10AT005
The purpose of this STTR is to develop comprehensive detailed kinetics for oxidation of C-SiC-SiO2-rubber in extreme oxidizing environment. This material is used as a coating on the outer surface of Navy weapon systems. In order to predict the fate of this material under extreme conditions and mitigate the degradation of the coating, a comprehensive oxidation mechanism is required. In Phase I, CFD ...STTR Phase I 2010 Department of DefenseNavy
SBC: Nastec, Inc. Topic: N10AT037
A unique type of air lubricated thrust bearing called a Wave Bearing is proposed to assist a rolling element bearing to carry the thrust load and to improve the bearing’s life when used in a micro gas turbine engine. The Wave Bearing technology will provide improved reliability, safety and life compared to rolling element bearings used alone, as well as to allow simplification of engine design a ...STTR Phase I 2010 Department of DefenseNavy
