  1. It's late, I'm tired, here's the album with descriptions for now. AASP 4
  2. I understand this. Does FAR handle the mechanics behind the reasoning for blunt stubby wings on hypersonic planes though? The X-15's wings aren't swept all that much...
  3. Perfect. While Report 4 focuses on something else, Report 5 is going to some sort of an Ode to Randazzo's engines. You'll like it
  4. I put two thrusters on the wing tips, and four on the nose cone/rcs tank. Fixed link: http://www./download/ftfp8vieu0q2bki/output_log.txt Thanks for all your help, by the way.
  5. Which RealPlume setting of which file should I modify to remove the lag from the massive column of smoke generated by SRBs?
  6. Thank you for the answers. 1-Testing showed that wing thickness has a significant effect on area ruling though... 2-Okay, thank you. 4-So I could translate an intake into the fuselage until only 10% of its original opening actually faces the airstream, and yet it manages to get maximal IntakeAir?
  7. Imgur album: http://imgur.com/gallery/U7H4x/new Clearly, the RCS thrusters are placed directly on the fuel tank, and I checked several times that the fuel/engine Gui setting is the same. Here's a Mediafire link to the output log. My untrained eyes see no major error.
  8. Hello, I have a few questions regarding FAR and supersonic airplanes in general: -How useful are thin wings? I usually make mine from 8cm to 4 cm thickness. Is there any advantage other than weight? -How important is area ruling in craft that travel at Mach 2 to 3, compared to the general streamlining (total front cross-section) of the craft? -Is it possible to control maximal flap deflection angle through an action group? -Does FAR, in combination with AJE, recognize a partially occluded air-intake? Thank you for answering.
  9. I've been using these engines extensively with their Real Fuels config in my RSS career (see link in signature). Sadly, they do not have a RealPlume config. Is there something that can be done to give them smoke effects?
  10. Tested in orbit, and confirmed that they produce up to 0.2 'units' per second in direct sunlight. Ground solar panels produce a value too small to measure. So it's more a question of the first solar panels being incredibly weak, requiring at least 3 of them in orbit facing the sun to power the smallest Avionics core...
  11. Hi. Under Real Fuels, RCS does not fire. Should I post the output.log?
  12. Anyone interested in a couple of FAR + Advanced Jet Engines + Real Fuels designs?
  13. Several months have past since Hammaguir's space center's last endeavor. It is May 1960, and tensions between world superpowers are high. A U2 plane has been shot down over Cuba. DeGaulle quelled the independence movement with talks of national self-determination back in January, but things don't look so sure now. French colonists, called 'pieds noirs', and Algerian revolutionaries, grouped under the FLN, shoot each other in the streets. Far above the turmoil, there are now both American and Soviet satellites. The scientists decide now is the time to unveil their plan to catch up with the world powers. Spurred on by French financing, driven by Cold War fears, Hammaguir builds and launches the Massad. The Satellite Launcher 4 version D, named Massad or 'Lifter', is a relatively lightweight fully liquid-fueled launcher designed using both US and homebrew technology. It will put the LOCS-4 Noor, Low Orbit Communications Satellite 'Light', in a circular 500x500km orbit. This launch will serve both as a technology demonstrator for the new Kerosene-Liquid Oxygen rockets developed by the French and Algerian scientists, and as a test bed for future launch vehicles lifting payloads in the 100-500kg range. The flight profile is aims for full horizontal acceleration by 100km altitude. We see here separation of the second stage and detachment of the aerodynamic fairings. The 250kN rated engine is used in a cluster of 5 for the first stage, and only one for the second stage. Previous iterations (SL-4A to C) failed to achieve orbit due to the use of outdated Ethanol-LOxygen boosters in the first stage. Shortly after SECO, or Second Engine Cut Off, the final stage ignites four 10kN vacuum engines running on Kerosene and Liquid Oxygen. On this screen, we see the Stage Recovery alert informing us that the first stage, with its 6 parachutes was safely recovered and is able to be refurbished for only 0.4% of its value. This is due to a combination of factors, including the difficulty of recovering it far away from the Space Center, and the relatively high speed at which it impacted the ground, rendering many parts unusable except as experimental data. The final stage has left the atmosphere. The small communications satellite is equipped with 6 STS-2 solar panels and a pair of Communtron-16 antennae. It weighs only 125 kilograms but hold enough electric charge to remain powered up while passing through Earth's shadow. The Massad's final stage extinguishes 2 of it's four engines and reduces thrust to a minimum. Without a reaction control system, it has to use thrust vectoring from its engines to align itself with the circularizing maneuver node. A final orbit of 544x539km is acheived. More was possible, but a short orbital period of 1h15 was desirable for a first attempt. All engines lit, the final stage reduces orbital velocity by over 1000m/s The final stage succumbs to Mach 20 aerodynamic heating at an altitude of 62km, over the Atlantic after passing over Mexico. More communications satellites will surely come, as the Hammaguir Space Center intends to follow in the footsteps of the US and USSR space programs. Surely, it would show the world that French-Algerian cooperation is still possible and might even appease warmongering parties on both sides. The news on the U2 being shot down despite its extremely high-altitude flight profile has instilled fear into all developers of aircraft capable of escaping the Soviet 'telephone pole' anti-aircraft missiles.Another approach is being investigated, that of speed. While an aircraft will never be able to outpace a guided missile, the combination of supersonic speed and high altitude might be able to extend the engagement time to a point where the majority of missiles run out of fuel. The American XF-108 program, a planned Mach 3 bomber has recently been cancelled, but the scientists as Hammaguir are being told that Lockheed has continued development along those lines. Unlike the great superpowers, the Algerian AeroSpace program is confident in the reliability of drone aircraft as test beds for innovative aerial technology. Based on the X-33, the X-34 extends the concept of rocket-boosted aircraft. The main intention is to verify the durability of thin-winged aircraft (8-4cm thickness) against near-hypersonic heating, as well as air-breathing performance at extreme altitudes. The 34th experimental aircraft, dubbed 'Pioneer', is the third iteration of the design. It mounts a 79kN turbojet rated for speeds of up to Mach 2.8, but is used mostly to drive the subsonic ascent up to an altitude of 12km Unlike previous X-craft from Hammaguir, the area ruling struggles to go lower than 0.72m2 due to the size of the liquid rocket boosters. After having reached the stratosphere, the Pioneer or Ra-id is alowed to accelerate to Mach 1.5 to improve the pitch authority of the control surfaces. At that point, the 1957 X-405 engines, generating up to 133kN of thrust, ignite and the craft enters a 7G ascent. Pushing past its thermal limit, the turbojet is very near the point of an explosive meltdown. It is shutdown as the X-34's thrust-to-weight ratio ticks past 5. The craft achieves Mach 3.63 on ascent. The apoapsis reaches a surprising 70km. Surprisingly, the thin wings do not overheat and maintain their integrity. The X-34C follows a ballistic curve to the thinnest parts of the atmosphere. The turbojet is fired with full afterburner. The lack of airflow produces nearly no thrust, and the engine heats up quickly without proper ventilation. A testament to the careful design of the Space center scientists, the craft manages to dive through speeds even faster than those achieved on ascent without the need for SAS. It doesn't do so much as a wobble. Landing was difficult due to the streamlining of the craft. Despite its very low landing weight of 6.7 tons, it sped over several kilometers at over 150m/s before falling under a sustainable lift/drag ratio. More will follow on the AASP, but trouble is brewing in the desert, and the scientists might not be shielded from the rest of the world for long....
  14. I like it. The satellite looked very realistic and the booster detachment was cool. Try again with a revised design! PS: maybe a little less pictures next time?
  15. This.... sounds more like a too-many-parts-on-the-screen issue than anything related with a tech tree mod.
  16. If you use SMURFF but not Real Fuels, can I interest you in exploring the solar system with the Kerbal Interstellar - Extended mod? I have yet to see the a playthrough done primarily with nuclear craft.
  17. It is best that you do something others haven't done several times already. I'm sure you'll think of something.
  18. The major advantage of an Algerian launch site, with regards to France, would have been the short distance rockets would have to cross from the french construction centers to the launch site. The Kourou launch site requires a several week trip over open sea, while Hammaguir requires a short trip over the Mididterranean and an overland trip that would eliminate most of the corrosion and accident risks of a long sea trip. You will see in my mission reports why this is called an alternate history though, and there's a story to tell, beyond the rockets and planes
  19. Do they appear and have to be cancelled, or do they not appear at all?
