by the military and NASA. FMEA standards have been established since the1960’s such as Mil-Std 1629A and SAE J1739 3, 4. There are also other standards for FMEA suchas IEC 60812 and SAE ARP5580. There are two SAE standards: J1739 is for automotive, andARP5580 is the aerospace recommended practice.The SAE J1739 standard identifies the intended use of FMEA as a “before-the-event” way toreduce the probability of needing corrective action for failure modes after the process or productis implemented 4. The FMEA is a continuous improvement tool that is useful three majorapplications: new designs or processes, changing existing designs or processes, and usingexisting designs or processes in new environments or applications 4. In the J1739 standard

), which was built at the Langley Laboratory in 1921-1923. This was the first wind tunnel Page 15.594.3that could operate at pressures higher than atmospheric, which allowed higher Reynolds numbersto be achieved at lower velocities. By the 1940’s supersonic wind tunnels were in use, eventhough Chuck Yeager had not yet broken the sound barrier. In 1972 a cryogenic wind tunnel wasbuilt at NASA Langley by injecting liquid nitrogen into the wind tunnel to cool the gas. Thislowered the viscosity and increased the Reynolds number, and this tunnel had the capability tomatch Reynolds and Mach numbers simultaneously up to Mach 1.2. Today the largest

styles.We studied the Learner Types set out by education psychologists, and developed a classificationapplicable to our students. These are related to the traditional definitions of types of intelligence.User-level definitions of these types are given below:The Barnstormer is eager to experiment, learning by trial and error. Too impatient with lengthy“derivations” to obtain elegant solutions, s(he) learns as needed and works intensely on adeadline. S(he) launches bold experiments, and ventures into the unknown with little hesitation.The Eagle: A separate category must be devoted to those who must have an eagle’s eye view ofwhat they are being taught, before they can focus. Long derivations lose them. These are thepeople who can rise above the

-Off Gross Weight (TOW).• Use a Wing Loading (W/S) from benchmarking, and find planform area S. Use airport gate or other commonsense constraints, or again benchmarking, to fix span, hence find aspect ratio.• For a selected cruise altitude and speed, find the lift and induced drag coefficients.• Guess a value for low speed zero-lift drag coefficient. Hence find total cruise drag, and speed for minimum drag. Find cruise L/D.• Starting with a thumb-rule (typically, that installed sea level static thrust is 30% of TOW, and that the plane must take off with 1 engine out), select a suitable engine and number of engines.• For the selected engine, find thrust-specific fuel consumption from published data, and estimate thrust at

you include all design parameters that you will need for your calculations in Task 2 below. 2. Aerodynamics at Cruise: a. Describe a typical high-speed cruise segment for a reconnaissance mission. Create a table summarizing the cruise Mach number, altitude, initial and final weights (most airplanes burn fuel when they fly), range of the cruise segment, and other mission values that are important. You will need to read some of the flight manual information to estimate these weights, ranges, etc. This information will be used to define the reference condition(s) for your aerodynamic analysis. b. Lift at initial cruise weight i.Estimate the lift at the

Through the use of case histories such as Apollo 13 andthe Space Shuttle Challenger “Normalization of Deviance” concept2 to lesser-known examplesfrom archives throughout the Agency, NASA engineers learn first hand from these highlyexperienced thought leaders who were there since the 1960’s, and worked through difficult featsand challenges to acquire invaluable experience.The goal of the SSD course is to examine the root causes of aerospace-specific mishaps, and theapplicable lessons that can be derived from these historical incidents. The majority of spacemishaps can be traced to easily recognizable and
