Jet Performance And Propulsion Research

In this module, some of the background considerations for jet and propeller aircraft performance were introduced by taking a closer look at the different propulsion systems. During the next module, you will apply these fundamentals to your aircraft example and its unaccelerated performance. Nevertheless, since all of your example aircraft are propeller-driven, it makes sense to divert your attention for a moment to introduce some of the application of performance principles in jet aircraft. Physics homework help

Choose a jet aircraft to use as your example for this activity.  It should not be an exotic jet aircraft, as you will need to find data online for the aircraft.  If you choose a military aircraft, make sure you are not using classified data to support your work.  Only use data that is available to all on the internet.  You will then use the data you gathered for this particular aircraft to show examples of your performance problems and how you derived them.

To provide an outlook to some of the aspects of next module’s unaccelerated performance, select a jet aircraft of your choice, choose three (3) of the following items of performance, and prepare an instructional presentation (utilizing a presentation tool of your choice – see resources in the Online Tools section) that explains in-depth how to find these different items of performance for a jet aircraft. This will be a standalone presentation and will not be attached to your comprehensive presentation project. Available choices: Physics homework help

  • maximum forward speed in level flight
  • absolute ceiling
  • best angle of climb airspeed
  • angle of climb
  • best rate of climb airspeed
  • rate of climb
  • maximum endurance airspeed
  • maximum range airspeed
  • influence of weight on performance
  • influence of altitude on performance

Ethical, Social, and Legal Implications of Disclosure
Prior to beginning work on this discussion, be sure to read the required articles for this week. .
You are a consulting psychologist for a local clinic and have been asked to review an ethically complex case. Please review the PSY699 Week four discussion case file (Links to an external site.) for detailed information on the case under review.

ORDER A PLAGIARISM-FREE PAPER NOW

In your initial post, explain how the APA Ethical Principles and Code of Conduct can be used to guide decisions in this ethically complex situation. Provide a suggested course of action for the clinic staff. Given the daughter’s age and the situation presented, integrate concepts developed from different psychological content domains to support your suggested course of action. Be certain to use evidence-based psychological concepts and theories to support your arguments. You may wish to consider the following questions as you construct your post. Psychology Homework Help.

  • Does the daughter have a right to know her diagnosis?
  • Does the mother have a right to not disclose the diagnosis to her daughter?
  • Does the mother have a right to privacy regarding her own diagnosis, which could be threatened if her daughter learns of her own status?
  • Should the staff tell the daughter if the mother does not want her to know?
  • If the daughter wants to know more about her condition, what should the staff say?
  • Are there other approaches the staff can take? If so, what are they?
  • Is further information required in order for you to create an ethically sound suggested course of action?

Guided Response: Review several of your colleagues’ posts and respond to at least two of your peers by 11:59 p.m. on Day 7 of the week. You are encouraged to post your required replies earlier in the week to promote more meaningful interactive discourse in this discussion.
Was the suggested course of action presented ethically sound based on the APA Ethical Principles and Code of Conduct? If so, how? If not, why not?  Did your colleague consider the legal ramifications of the course of action he or she suggested? Were the arguments for the suggested course of action supported by appropriate evidence-based psychological concepts and theories? What other resources might you suggest to your colleague that would inform the response to this case? Was the recommendation made culturally sensitive? What developmental issues did your colleague consider? What other issues might you suggest for further review in this case? Psychology Homework Help.

Independent Project: Drag

For the speeds in the first column, start with your aircraft’s stall speed, then continue in intervals of 20 or less knots (consider increasing the detail in the important portions near (L/D)max – see also this module’s tutorial videos within the 3.2 Lectures and Tutorials), and continue to at least a speed of 300kts or higher if required to allow for answering the questions and explaining all drag phenomena.

To create this table you can use the Excel Spreadsheet ASCI 309 Table Drag Table (XLSX) located under “Field and Presentation Resources”. Physics homework help

To fill out your table and subsequently create a diagram with the total drag curve, you will need to research a variety of variables, formulas, and components. Again, the emphasis in this project task is on explaining your methodology as if you attempted to instruct someone unfamiliar with the aerodynamic details and relationships. Therefore, make sure to detail all assumptions, all formulas used, and all steps that were taken. The following will give you some starting points for your search and consideration. Physics homework help

  1. Assumptions and conditions:
    • Assumed atmospheric conditions
    • Calculated dynamic pressure (second column; based on the assumed atmospheric conditions and KTAS)
  2. Necessary aircraft information:
    • Wing size and configuration (e.g., AR &efficiency factor – if you can’t find an efficiency factor for your aircraft, you can make an assumption [i.e., pick a value] somewhere between 0.75 and 0.85)
    • Weight(should, of course, fall between MTOW and empty weight of your aircraft)
    • Airfoil information (e.g., CLmaxfrom last module & CDP – if you can’t find the CDP for your entire aircraft, you can utilize the minimum drag for your airfoil and add a value of 0.02, which will account for the parasite drag of your aircraft’s fuselage) or if you are still having trouble, just use a Cdp of .021 which is a common Cdp.
  3. Required formula (for inputs see the formula summary )
  4. Resources and Inputs page)
    • Dynamic pressure
    • Lift equation (two forms: one solved for stall speed and the other solved for required CL)
    • Drag coefficients (CDi & CD)
    • Application of coefficients to find actual forces (Dp, Di, Dt)
    • Possibly wing geometry conversions (e.g., wingspan and area into AR or wingspan and average chord into AR)
  5. Do not forget to create the diagram.

Once created, utilize your derived table and diagram data to answer the following associated questions:

  1. What are the minimum drag parameters for your aircraft?
    • Minimum drag value D(min)
    • Speed VD(min)at which minimum drag occurs
    • Relationship between Dpand Di at D(min)
  2. What are the maximum lift to drag ratio CL/CDparameters for your aircraft?
    • (CL/CD)maxvalue
    • Speed at which (CL/CD)maxoccurs
  3. Compare answers in A. and B. and comment on the findings.
  4. Explain which of your derived values will allow glide performance predictions for your aircraft and quantify best glide conditions with specific values. Physics homework help

understanding of Newton’s laws

Before the time of Galileo and Newton, many learned scholars thought that a stone dropped from the top of a tall mast on a moving ship would fall vertically and hit the deck behind the mast by a distance equal to how far the ship had moved forward during the time the stone was falling. In light of your understanding of Newton’s laws, what do you and your classmates think about this idea?
Discussion board questions should be answered in the textbox and not submitted as attachments. Students are required to acknowledge and respond to a minimum of two of their peers’ responses in each discussion thread by Sunday of each week.understanding of Newton’s laws
