Bombardier Aerospace: Internship Summary

The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases from subsonic to transonic.

When nitrous oxide is used in cars and rockets, it vaporizes, causing a significant cooling effect on the intake air. You increase the density of the air when the intake air pressure is reduced. This provides even more oxygen in the cylinder which is a good thing.

A period of 5 years from 2008 to 2013 is considered for combustion instabilities performance evaluation before modifications measures are fully implemented. In the past major changes in the gas turbine exhaust gas temperature distribution as well as reduced margin to the combustion stability were observed in all 5 S1 gas turbines, leading to hot/cold spots events and trips, Acceleration Max 1,Max 2 unload events and Max 3 trips.

AIAA has earned an international reputation as the preeminent publisher of cutting-edge aerospace books and journals, and the leading source of aerospace industry archives, dating back to the early 1900s. Over the past eight decades, AIAA and its predecessor organizations have published over 300 books and almost 200,000 technical articles. AIAA’s current publications include seven technical journals, a magazine, three book series, national and international standards documents, a growing number of e-books and other electronic products, and a full-service, interactive Web site. For the most authoritative technical publications, look to

The company researched in this report is Bombardier Canada. Bombardier has three headquarters; the Aerospace Administrative center is in Dorval, the Transportation Engineering site and divisional headquarters, and the Bombardier Inc. headquarters are both in Montreal (Bombardier Canada - Sites and contacts, 2014).

Canadair 50 seat regional jets are continuing to be turned out at a rate of 60

Bombardier (BBD) business has evolved from the early years of snowmobile manufacturing to a diversified business in the transportation industry. Now, more revenue comes from its aerospace division in comparison to recreational products and even transportation. BBD wanted to expand its transportation division (BT) and had recently concluded the negotiation of Adtranz, a company twice the size of BT. Using the Strategic Analysis Framework, below is the rationale to justify the acquisition of Adtranz for BBD.

1. Current Performance As of September 30, 2012, the total number of 138 units of CSeries100 and CSeries300 commercial jets are ordered, while it now expects the first delayed delivery before the end of next June, a delay that had been anticipated due to high performance milestones set by company .According to Pierre Beaudoin CEO ,company requires more time to meet certain CSeries program targets but others had been met and the company and its suppliers have "now fully harmonized all commitments to the program's schedule."

This summer I work at Pratt Industries’ recycling division in Conyers, GA as an accounting intern. I report to the division controller and help him with various accounting projects. My initial involvements include locating transaction information and performing late archiving with SAP on invoices, requesting and reviewing sales tax exemption certificates, and updating contract records. I also work on many small projects, including extracting budget information and conducting basic cost analysis for baler contracts. As the weeks progress, I am increasingly exposed to valuable information about the recycling industry, general business practices, workplace environment and my future career choices.

This report aims to investigate the effect the angle of attack of an aerofoil has on the air flow around it. This was done by recording the lift and drag forces the aerofoil experienced when positioned at different angles of attack. The experimental lift force the aerofoil experienced when positioned at different angles of attack was then compared with theoretical values. An attempt was made to explain any discrepancies between experimental and theoretical values.

The location and proper sizing of intake and exhaust louver shall be determined precisely which the air flow from entry to exit would not be obstructed.

William et al [3], in their investigation of the cap-shock pattern in a rocket nozzle, pointed out that significant reduction in thrust performance of launch vehicle results due to imperfect exhaust profile. They also mentioned in their investigation, that the contour of the nozzle directly influences the shock structure and subsequent plume

The performances achieved for IFCE and IMEP using this method are therefore unrealistically high and serve only as a general indication [3]. This Paper extends the previous investigations from [3] to real Atkinson cycles by using the simulation tool BOOST (AVL Co). This tool allows to take into consideration the true geometrical dimensions of the engine components (cylinder, valves, channels, pipes, manifolds, turbocharger, intercooler, silencer etc.) and the losses caused by friction and heat transfer along the intake and exhaust gas pipes. In addition, the power balance of turbochargers determines the actual boost pressure level of the engine. The turbochargers (TC) are modeled for these investigation in a simple manner. It describes the expansion process in the turbines (Tx) by means of their discharge coefficients while the air compaction in the compressors occurs up to a maximum pressure ratio, which depends on the available turbine output. To be able to simulate cycles with very high boost pressures as well, three intercooled TC are placed in line (three-stage turbocharging, see Fig. 1). When the boost pressure required for preserving the pressure limit on the cycle is low, the superfluous TC are kept in use (i.e. are not bypassed). The expansion and compression ratios of the turbines and compressors tend gradually toward 1, i.e. these TC switch off themselves thermodynamically. The asymmetrical crank mechanism used here
