New Capabilities for All-Weather Microwave Atmospheric Sensing Using Cubesats and Constellations
SSC18-II-07 New Capabilities for All-Weather Microwave Atmospheric Sensing Using CubeSats and Constellations W. Blackwell, K. Clark, D. Cousins, D. Crompton, A. Cunningham, M. Diliberto, L. Fuhrman, R. Leslie, I. Osaretin, and S. Michael MIT Lincoln Laboratory [email protected] ABSTRACT Three MIT Lincoln Laboratory nanosatellite missions flying microwave radiometers for high-resolution atmospheric sensing are in varying stages of development. Microwave instrumentation is particularly well suited for implementation on a very small satellite, as the sensor requirements for power, pointing, and spatial resolution (aperture size) can be accommodated by a nanosatellite platform. The Microsized Microwave Atmospheric Satellite Version 2a (MicroMAS-2a), launched on January 11, 2018 and has demonstrated temperature sounding using channels near 118 GHz and humidity sounding using channels near 183 GHz. A second MicroMAS-2 flight unit (MicroMAS-2b) will be launched in Fall 2018 as part of ELANA-XX. The Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission was selected by NASA in 2016 as part of the Earth Venture–Instrument (EVI-3) program. The overarching goal for TROPICS is to provide nearly all-weather observations of 3-D temperature and humidity, as well as cloud ice and precipitation horizontal structure, at high temporal resolution to conduct high-value science investigations of tropical cyclones. TROPICS will provide rapid-refresh microwave measurements (median refresh rate of approximately 40 minutes for the baseline mission) over the tropics that can be used to observe the thermodynamics of the troposphere and precipitation structure for storm systems at the mesoscale and synoptic scale over the entire storm lifecycle. -

Diffusion Flames and Supersonic Combustion
DIFFUSION FLAMES AND SUPERSONIC COMBUSTION BY I.DA-RIVA A.LINAN E. FRAGA J. L. URRUTI A INSTITUTO NACIONAL DE TECNICA AEROESPACIAL «ESTEBAN TERRA DAS» MADRID (SPAIN) October i, 1566 ABSTRACT The paper describes some analytical work connected with the purely diffusive mode of supersonic combustion. The basic problems considered have been: the study of the hydrogen-air diffusion flames, under hoth close to and far from equilibrium conditions, and the study of the aerodynamic field near the injector exit when the ratio of injected to outer total pressures is small. The internal structure of hydrogen-oxygen diffusion flames close to equilibrium has been studied using the first order approximation of an asymptotic expansion method, in which the large parameter represents the ratio between a characteris tic mechanical time and a chemical time. Far from equilibrium conditions, the above mentioned solution fails. However, when a free jet of hydrogen.parallel to the air stream is used for injection purposes, a very simple near frozen approach may be used. The main simplifying features of such an approach being; the use of an overall chemical reaction, the assumption that fuel and oxidizer jnix without appreciable depletion and chemical heat release, and the linearization of the mixing problem. Finally a discussion of some means of improving the mixing process, near the injector exit, is made, using some experimental evidence from work on related problems by other groups.

Make America Boom Again: How to Bring Back Supersonic Transport,” Eli Dourado and Samuel Hammond Show That It Is Time to Revisit the Ban
MAKE AMERICA BOOM AGAIN How to Bring Back Supersonic Transport _____________________ In 1973, the Federal Aviation Administration (FAA) banned civil supersonic flight over the United States, stymieing the development of a supersonic aviation industry. In “Make America Boom Again: How to Bring Back Supersonic Transport,” Eli Dourado and Samuel Hammond show that it is time to revisit the ban. Better technology—including better materials, engines, and simulation capabilities—mean it is now possible to produce a supersonic jet that is more economical and less noisy than those of the 1970s. It is time to rescind the ban in favor of a more modest and sensible noise standard. BACKGROUND Past studies addressing the ban on supersonic flight have had little effect. However, this paper takes a comprehensive view of the topic, covering the history of supersonic flight, the case for supersonic travel, the problems raised by supersonic flight, and regulatory alternatives to the ban. Dourado and Hammond synthesize the best arguments for rescinding the ban on supersonic flights over land and establish that the ban has had a real impact on the development of supersonic transport. KEY FINDINGS The FAA Should Replace the Ban on Overland Supersonic Flight with a Noise Standard The sonic boom generated by the Concorde and other early supersonic aircraft was very loud, and as a result the FAA banned flights in the United States from going faster than the speed of sound (Mach 1). This ban should be rescinded and replaced with a noise standard. A noise limit of 85–90 A-weighted decibels would be similar to noise standards for lawnmowers, blenders, and motorcy- cles, and would therefore be a reasonable standard during daytime hours. -

Strategic Network Design for Parcel Delivery with Drones Under Competition
Strategic Network Design for Parcel Delivery with Drones under Competition Gohram Baloch, Fatma Gzara Department of Management Sciences, University of Waterloo, ON Canada N2L 3G1 [email protected] [email protected] This paper studies the economic desirability of UAV parcel delivery and its effect on e-retailer distribution network while taking into account technological limitations, government regulations, and customer behavior. We consider an e-retailer offering multiple same day delivery services including a fast UAV service and develop a distribution network design formulation under service based competition where the services offered by the e-retailer not only compete with the stores (convenience, grocery, etc.), but also with each other. Competition is incorporated using the Multinomial Logit market share model. To solve the resulting nonlinear mathematical formulation, we develop a novel logic-based Benders decomposition approach. We build a case based on NYC, carry out extensive numerical testing, and perform sensitivity analyses over delivery charge, delivery time, government regulations, technological limitations, customer behavior, and market size. The results show that government regulations, technological limitations, and service charge decisions play a vital role in the future of UAV delivery. Key words : UAV; drone; market share models; facility location; logic-based benders decomposition 1. Introduction Unmanned aerial vehicles (UAVs) or drones have been used in military applications as early as 1916 (Cook 2007). As the technology improved, their applications extended to surveillance and moni- toring (Maza et al. 2010, Krishnamoorthy et al. 2012), weather research (Darack 2012), delivery of medical supplies (Wang 2016, Thiels et al. 2015), and emergency response (Adams and Friedland 2011). -
