Effect of Date and Location on Maximum Achievable Altitude. Mission profiles for a solar powered aircraft were generated over a range of latitudes and dates. These profiles were used to determine which latitude-date combinations produced the highest achieavable altitude. Based on the presented analysis the results have shown that for a given time of year lower latitudes produced higher maximum : Anthony J. Colozza. Zhifeng Wang, in Design of Solar Thermal Power Plants, Solar Altitude Sunrise Time, and Sunset Time of Beijing. Beijing is located near 40°N and enjoys a solar altitude change of 46°52′ during the year. Around midday, the solar altitude changes from 26°34′ on the winter solstice (December 22) to 73°26′ on the summer solstice (June 21), while sunshine duration changes. Firstly, since the temperature and solar irradiation both increases with increase in altitude , Nepal as a mountainous and hilly country has higher solar output potential. Secondly, cost of PV.
Effect of Date and Location on Maximum Achievable Altitude for a Solar Powered Aircraft solar powered aircraft were generated over a range of latitudes and dates. These profiles were used to. As we can see, above, solar minimum (~) is still in full effect. surpassed with the fewest sunspots, making this the deepest solar minimum in more than a century. is on track to rival as another year with the fewest sun spots. Solar elevation angle (for a year) Solar culmination and equation of time.

Planet's position on ecliptic and equatorial planes. Rising and setting of the. The program retrieves the current date and time from your computer, and fills in these values in the date/time fields. To perform calculations for a different date, simply select the month in the pulldown box, and enter the day and four digit year in the appropriate input boxes. Time of day for the calculation can be changed in the same way.
OPTIMISATION OF A SOLAR-POWERED HIGH ALTITUDE LONG ENDURANCE UAV Fig. 3 Solar irradiance per unit area available vs time and distribution of energy to motors, battery and payload, and altitude vs position (22th of December at 45° of latitude and 18km of altitude) Electric motor The mass of electric motors is deﬁned by the. Convective array cooling for a solar powered aircraft [microform] / Anthony J. Colozza; Preliminary design of a long-endurance Mars aircraft [microform] / Anthony J. Colozza; Effect of date and location on maximum achievable altitude for a solar powered aircraft [microform] / An. A simple numerical model that describes the altitude effect of solar UV flux under cloud-free conditions was developed and tested. The model computes the direct and diffuse UV irradiances for the wavelength range – nm, at any sub-polar location and time (restricted to arid areas). The effects of the available solar irradiance and daylight of the city on the maximum take-off weight and wing span of a small solar-powered UAV were studied. The analysis indicates that daylight duration is as important as the available solar irradiance to the performance of the solar-powered .
