Embry ASCI310 Module 1 Assignment
Exercise 1 latest 2016 December
Exercise 1: Rectilinear Motion
Background
The average accelerations of a US
Navy fighter jet takeoff to an US Air Force fighter jet takeoff are very
different. The aircraft conditions are the
same except the Air Force fighter is on a 12,000-ft dry concrete runway and the
Navy fighter is on the catapult of an aircraft carrier. (Hint: You will have to use two different methods because
you are not given the catapult force, but you have the catapult distance. Assume aircraft is airborne after the catapult stroke.)
Givens:
Gross Weight (W) = 55,000 lb
Average Drag (D) = 9,000 lb
Average Friction (f) = 1,500 lb
Average Thrust (T) = 36,000 lb
Lift Off Speed ( VLO) 180 KTAS
Catapult Distance = 350 ft
Average Drag (D) = 9,000 lb
Average Friction (f) = 1,500 lb
Average Thrust (T) = 36,000 lb
Lift Off Speed ( VLO) 180 KTAS
Catapult Distance = 350 ft
6. Find potential, kinetic, and total energy of this aircraft
after takeoff at the following conditions:
Weight = 50,000 lb
Altitude = 10,000 ft
Airspeed = 300 KTAS
7. Given conditions of #6, find new altitude if the aircraft
raises the nose to capture 250 KTAS but keeps the thrust at the same setting
and, for simplicity, assume the drag stays the same. Think of this as a Constant Energy Problem.

ASCI 310: Aircraft Performance
Research Project
Objectives
One of the requirements for this
course is an Aircraft Performance Research Projectthat entailsplanning a
flight from Denver International Airport (KDEN) to Chicago O'Hare International
Airport (KORD) for a given aircraft, weather conditions, and assumptions. The objective is to apply what has been learned throughout
this course. Drawing on aeronautics theory and
using the performance charts and equations presented in the course, each
student is to answer a sequence of questions that step through the planning
process. Remember, as with all of the exercises, all work
(calculations) must be shown as much as possible. After all of the questions have been answered, the next
task is to create a two-dimensional representation of the flight path showing
the airspeeds, distance, fuel burned, and fuel remaining for the Takeoff,
Climb, Cruise, Descent, and Approach phases of the flight.
Project Files - Save all of the
files to your computer or a memory device for ready access outside of this
course. In Week 5, familiarize yourself the project files to get an
idea of the expectations. Much of the knowledge and skills for
solving this project are covered in Modules 6 through 8.
Here are some important notes for
this project:
2. To find out how many passengers you can transport, you need
to know how much fuel you need for the flight.
6. Answers can vary due to chart interpretations and because
one wrong answer will carry throughout the project. Consequently, this will be considered in the grading.
Deadline
The Aircraft Performance Research
Project is due by the last day of the course. The deliverable (answers and flight profile) must be
submitted using the activity link in Module 9. You may submit the deliverable as a Microsoft Word or
PowerPoint file or an Adobe PDF file.
Project Evaluation
Thecompleted Project will be
evaluated using this Project Evaluation Rubric on a 0 to 100-pt scale. The score on theproject is worth 15% of the course grade.

Module 1 - Discussion: What does research mean to you?
100 100 unread replies. 100 100 replies.
Discussion Topic: What is your definition of research? You may have “researched” a topic of personal interest in the recent past. Perhaps it was related to which degree to pursue, which branch of the military to join, which career to pursue, which car to purchase, which neighborhood to purchase a home in, or other decisions you needed to make. When you personally research a topic, it is something inherently interesting to you and you research it to learn about it so that you can make an informed decision. In this discussion board, introduce yourself by briefly telling your classmates your definition of research and about something you recently researched. Describe the techniques and tools you used to research your topic.
Posting Instructions: You should make your initial discussion board posting no later than the fourth day of the week. Later in the week, return to the discussion, read the postings of your classmates, and comment on at least two of those.

Module 3 - Discussion: Data Collection - Questionnaire
83 83 unread replies. 83 83 replies.
An undergraduate student named Nicki created a Questionnaire Preview the documentView in a new windowto gain insight into people’s attitudes toward online shopping. To determine the attributes relevant to his study, Nicki first conducted face-to-face interviews. Then based on a rigorous analysis of those interviews, he developed the questionnaire. Read through Nicki’s proposed questionnaire and answer the following questions.
Discussion Topic:
Nicki’s questionnaire starts with questions seeking personal information from the respondents. Some researchers ask for personal data at the end rather than the beginning of the questionnaire. Which do you prefer and why?
Nicki uses a lot of closed questions that ask respondents to make choices among a set of alternatives given by the researcher. In closed questions, care must be taken to ensure that the alternatives are mutually exclusive and collectively exhaustive. Are there any of Nicki’s questions that are not mutually exclusive and collectively exhaustive? If so, which ones? Tell how you might revise those questions to make them mutually exclusive and collectively exhaustive.
Poor phrasing of questions can cause respondents to refuse to answer them or to answer incorrectly (either on purpose or because of misunderstanding). Do you think any of Nicki’s questions are poorly worded and should be reworded? If so, which ones and how would you reword the items?

Embry RSCH202 Module 3 Turn in Literature Review Draft Latest 2016 November
The Literature Review Assignment was introduced in Activity 2.6. Take advantage of this opportunity! The purpose of the draft is to give you an opportunity to get feedback from your instructor prior to writing your final proposal – the draft isn’t expected to be perfect. It will be graded, but will count only 2% of your final course grade. A good grade on the draft means that you submitted it on time; your instructor feels that you put good effort into it, and that it addresses the required topics. The literature review that is due in Module 5 will be subject to much more stringent grading criteria. That means it is possible that you could receive a higher grade on a draft than on the corresponding portion of the final complete proposal.
