space program does not have an impact on our country‚ as the world has become more modernized and less dependent on new technologies for daily survival. Additionally‚ critics believe technology used in Apollo missions‚ such as space rocketry and jet propulsion used by NASA forty years ago‚ becomes outdated‚ too fast. Technology being used today is not always newest available‚ or neither will it provide instant results of new findings the moment the probe or satellite is slung into orbit. In

13. Aircraft Performance In this chapter we will make the connections between aircraft performance and propulsion system performance. For a vehicle in steady‚ level flight‚ as in Figure 13.1‚ the thrust force is equal to the drag force‚ and lift is equal to weight. Any thrust available in excess of that required to overcome the drag can be applied to accelerate the vehicle (increasing kinetic energy) or to cause the vehicle to climb (increasing potential energy).

Only a year later he married Janet Shearon. He soon became a skilled test pilot and flew some of the early models of such jet aircraft as the F-100‚ F101 and F-104. Neil Armstrong was selected as one of the first there pilots of NACA for the x-15 rocket plane‚ and he made seven flights in the prototype spacecraft. He received an

Chandrayaan-1 (Sanskrit: चंद्रयान-१‚ lit: moon vehicle[3][4] [pic]pronunciation (help·info)) was India’s first unmanned lunar probe. It was launched by the Indian Space Research Organisation in October 2008‚ and operated until August 2009. The mission included a lunar orbiter and an impactor. India launched the spacecraft with a modified version of the PSLV‚ PSLV C11[2][5] on 22 October 2008 from Satish Dhawan Space Centre‚ Sriharikota‚ Nellore District‚ Andhra Pradesh‚ about 80 km north of Chennai

MACHINES FOR AUTOMOTIVE APPLICATIONS USING EFFICIENCY MAPS S. M. Lukic and A. Emado Illinois Institute of Technology Abstract: In most industrial applications of motor drives‚ motors operate at one or a few predefued operating points. However in propulsion applications‚ the motor is used over the entire torqudspeed range. Therefore‚ the motor has to be studied at all possible torqudspeed combinations within the motor operating envelope. Efficiency maps are a convenient way to represent motor drive
