  1. Gateway To Space ASEN / ASTR 2500 Class #19 Colorado Space Grant Consortium

  2. Announcements…

  3. Announcements… - 25 days to launch - Website updated - Launch Vehicle In-class exercise - Launch vehicle lecture - Orbits and Mission Design Plan 10/23/08 Part A (15 minutes) 10/30/08 Part B (15 minutes) 11/18/08 Part C (45 minutes)

  4. Announcements… - This Thursday… - Each team will have 5 minutes to demonstrate something related to there science mission in front of the class - You may use projector or other A/V resources but slides are discouraged - We will spend roughly one hour doing this

  5. Announcements… - Next Tuesday we will have a guest lecture on Spacecraft Attitude Determination and Control (ADCS) - Bruce Schulz from Lockheed Martin - I will not be here but Kristina, Bruce Davis, and Brian Sanders will be present

  6. Announcements… - Who is still waiting for hardware? - Who is completely lost? - Who needs something?

  7. One minute: - How will the presentations at the Design Expo work? - Do we need to catch all this information as if it will be potentially on the final? - What do you do about jerk team members? - I don’t have nice clothes here - What are the LRR cards? - Is there community service available by Space Grant? - Tim May and scheduled meetings and how are we to learn programming? - What string are we supposed to use for our whip test?

  8. One minute: - Why do we have to be worried? - Can you go over the camera code in more detail? - Does this only work for Canon cameras? Only this model? - What if it stops working? - What can you change? - Whip test with mass sim? - Drop out of a plane? - Is it normal for team dynamics to fall apart now? - Craziest picture recorded by balloonsat? - Due date for the team video?

  9. One minute: - Do the videos get watched by everyone at the end of class? - How much drag does the balloonsat undergo? - What colorful language was used during zipline? - How many pictures will we get from the flight? - Why don’t you ever answer my questions in class? - What has been your most embarrassing moment?

  16. Before we get started… In Class Exercise

  17. Building a Rocket on Paper: - Please wait, everyone will be opening your envelopes in a minute - Not every rocket design will work... - YOU ARE A ROCKET ENGINEER: You make $70,000.00 a year and you have a masters degree and drive a company Viper

  18. Building a Rocket on Paper: • 1.) Build a rocket with the right people. • You will need… • Payload Specialist • Thruster Specialist • Fuel Expert • Structural Engineer

  19. Building a Rocket on Paper: 2.) Calculate total mass of your rocket, must include everything. Total mass = mass of fuel+payload+ structure+thrusters

  20. Building a Rocket on Paper: • 3.) Calculate the thrust needed to lift your rocket off the launch pad • Needed thrust = total mass * gravity • F = m * a [Newtons, N]) • 1 N =1 kg*m/s2 • 1 pound-force = 4.45 N • a=gravity=10 m/s2

  21. Building a Rocket on Paper: 4.) Calculate the total lift (thrust) capability of your rockets thrusters 5.) Does your structure support the total weight of the rocket? 6.) Do you lift off the ground or did you crash and burn? 7.) Could you lift off the surface of the moon? g(moon) = 1/6 g(earth)

  22. Ion Engine: Max Thrust = 200 N Engine/Fuel Mass = 9,000 kg (90,000 N) Max Thrust (minus Engine/Mass) = - 82,000 N Remaining Mass = - 8,200 kg

  23. Cold Gas Engine: Max Thrust = 22,000 N Engine/Fuel Mass = 1,700 kg (17,000 N) Max Thrust (minus Engine/Mass) = 5,000 N Remaining Mass = 500 kg

  24. Propane Engine: Max Thrust = 100,000 N Engine/Fuel Mass = 8,000 kg (80,000 N) Max Thrust (minus Engine/Mass) = 20,000 N Remaining Mass = 2,000 kg

  25. Liquid Engine: Max Thrust = 1,500,000 N Engine/Fuel Mass = 103,000 kg (1,030,000 N) Max Thrust (minus Engine/Mass) = 470,000 N Remaining Mass = 47,000 kg

  26. Solid Engine: Max Thrust = 3,000,000 N Engine/Fuel Mass = 52,000 kg (520,000 N) Max Thrust (minus Engine/Mass) = 2,480,000 N Remaining Mass = 248,000 kg

  27. Launch Vehicles Past, Present, Future & Sci-Fi Future

  28. Outline: • Fine Print • Background & Rocket Types • Past • Present • Future • Sci-Fi Future

  29. Rocket Types: • I don’t know everything about Launch Vehicles • I may not be able to answer your questions • This lecture is to expose you to all the different types of launch vehicles • I can quit at any time

  30. Background: • Thrust = the force that moves • Impulse = force over period of time • Specific Impulse = Isp = ratio of impulse to fuel used • Higher Isp usually indicates low thrust but very little fuel used • Will learn more in Propulsion Lecture • Rocket Types include: Solid, liquid, hybrid

  31. Past

  32. Past/Present: Scout: (Solid Controlled Orbital Utility Test) Thrust: 464,700 N (104,500 lb) Fueled Weight: 21,750 kg Payload to Orbit: 270 kg LEO # of Flights: 188, 105 successful

  33. Past: Jupiter C Thrust: 334,000 N (75,090 lb) Fueled Weight: 29,030 kg Payload to Orbit: 9 kg LEO (14 kg) # of Flights: 6, 4 successful Explorer I

  34. Past: Mercury Redstone Thrust: 347,000 N (78,000 lb) Fueled Weight: Not Found kg Payload to Orbit: 9 kg LEO # of Flights: 5, 5 successful Chimp “Ham”, Shepard, and Grissom

  43. Saturn V: Can it be built today? Not really… According to Prof. Jesco von Puttkamer, Program Manager of Future Planning at NASA in 1999… - The blue prints still exist, however only on microfilm. - All the subcontractors and suppliers are no longer around. - The technology is old. We can build much smaller and lighter rockets today.
