| In space applications, the main concern of particle deposition arises from the undesirable effects of surface obscuration on contamination-sensitive surfaces. The development of effective mitigation strategies to minimize particulate contamination requires the understanding of particle transport and deposition as well as the associated physical factors affecting the processes. The knowledge gleaned from the state-of-the-art literature review presented here can be applied to an enclosure scale as small as a spacecraft ... |

| Access to space has always been a challenge, especially for organizations with limited budgets. In the last decade a group of universities has overcome many of the obstacles associated with placing experiments on orbit by using a nano-satellite standard called the CubeSat. In addition to universities many private, commercial, and government organizations are now coming to appreciate the advantages of the CubeSat standard resulting in rapid growth in the CubeSat ... |

|
| Operationally Responsive Space (ORS) is focused on putting satellites in orbit in significantly less time than it currently takes. ORS is based on responding to an operational need quickly, but it should not be thought of as a new way to place national systems in orbit. Operational needs likely result from a need to augment an existing system or to replace a portion of an existing system. Whether a satellite ... |

|
| The importance of Unmanned Aircraft Systems (UAS) to warfighters has been growing. Each loss (regardless of whether the entire UAS or parts of it) has become more expensive and unaffordable in both an operational and monetary sense. An unmanned aircraft (UA) loss may mean that critical missions cannot be performed and millions of dollars of investments on the UA lost. As most existing UAS were designed to be inexpensive and ... |

| This paper presents recent developments on two innovative types of crashworthy cargo restraints for high mass rotorcraft payloads: textile-based devices and flexible matrix composite devices. Each type of device employs energy dissipation mechanisms to arrest the motion of payloads and limit the maximum load transmitted to tie-down points, thereby maintaining control over payload motion and improving crew survivability in the event of a crash or hard landing. The benefit of ... |

| The Navy procured 18 Ohio (SSBN-726) class nuclear-powered ballistic missile submarines (SSBNs) between FY1974 and FY1991 to serve as part of the U.S. strategic nuclear deterrent force. They are commonly called Trident submarines because they carry Trident submarine-launched ballistic missiles (SLBMs). The first Trident entered service in 1981, the 18th in 1997. The first 8 (SSBNs 726 through 733) were originally armed with Trident I (C4) SLBMs; the final 10 ... |

| Fixed-wing micro air vehicles (MAV) are very attractive for outdoor surveillance missions since they generally offer better payload and endurance capabilities than rotorcraft or flapping-wing vehicles of equal size. They are generally less challenging to control than helicopter in outdoor environment. However, high wing loading associated with stringent dimension constraints requires high cruise speeds for fixed-wing MAVs and it has been difficult so far to achieve good performances at low-speed ... |

| This report describes the 2015 Navy Sea base, operating within the interim heavy airlift (iHL) concept first proposed in NSWCDD/TR 06/52. The iHL concept proposes that existing aircraft "snatch pickup" a logistics glider from a Sea base helipad, flight deck, or nearby littoral water surface for aerial sustainment of the tactically maneuvering expeditionary warfighter. This report proposes the methods and also models Sea base performance in processing logistics gliders. |
