  1. Kyasish'ev EK-4/EK-4e "Teal" small regional jet plane The EK-4 family is heavily based on Kyasish'ev's highly experimental SK-2 "Harfang" science plane. Although the requirements for a commercial airplane were highly different from a scientific plane, the "Teal" shares the same general shape and principles, such as high cambered wings with a slight angle of incidence, T-shaped stabilisators as well as a rear wheel to prevent tail strikes. In order to meet the requirements for a commercial version, the main wing was re-designed without leading edge slats, but with an overall larger lifting coefficient, leading to increased reliability and decreased costs while retaining the performances of the versatile SK-2. The motorisation was also simplified, and the high-maintenance inline air intakes were replaced with a more classical engine setup. This allowed also the use of the whole fuselage for passengers, making the EK-4 a very compact plane. Technical specifications: Plane EK-4 EK-4e Dimensions (l/w) 12.8m/13.8m 14.7m/13.8m Weight (wet/dry) 15.4t/11.0t 16.4/12.0t Pricing 19,493,000 20,043,000 Parts 37 38 Flight characteristics: The wing allows for relatively low-speed take-off (60 to 65m/s), especially when the flaps (AG3) are used. The EK-4's ideal flight envelope lies at altitudes of 8000 to 11000m, with speeds of 450 to 500kn (230 to 255m/s). This brings the range of both planes to 1600km, well over the requirements for small regional planes (1600km is KSC-Baikerbanur-KSC on one tank). Although the EK-4 are able to fly past Mach 1 at 5000m, it is strongly recommanded that pilots avoid such tomfoolery, as it will put unneeded strain on the airframe, possibly resulting in voided guarantees and permanent damage.

  2. That Badger is a thing of beauty! The platform, especially, has given me a few ideas...
  3. Weekly Aircraft Development Competition

    Is there still place for an entry? I hereby present Kermann Aviation's S-4 Goose. Weight (wet): 19.610 tons Wingspan: 17.7 m; Length: 17.7 m; Height: 5.4 m Range: Over 900 km Propulsion: 2x JX-4 Whiplash turboramjets Crew: one pilot + one scientist The design of this craft benefitted enormously from the previous challenge, especially with the leading slats.

    Can you be more specific on the payload ? (E.g. does the booster have a payload, what should be the weight of the rocket, etc.)
  5. Weekly Aircraft Development Competition

    50 meters is a lot less than I thought... After a number of trials with a Goldberesque construction which simulate the carrier deck, I think I can take off in clean configuration, but just not with bombs and missiles... Quite frustrating... However, I've learned a great deal of things, which will certainly be immensely useful for the following crafts also... @NotAnAimbot How precise can you be when landing ? I decided against building a VTOL because the landing manoeuvers were taking wayyyy too much time and resources, but might go back to it.
  6. Weekly Aircraft Development Competition

    Quick question: I notice KLAWs on the carrier deck. Can we assume that these are placed in order to hold the plane as it spools up its engine, in a similar way catobar aircraft carrier work?
  7. Weekly Aircraft Development Competition

    Sadly I missed the deadlines for the two first challenges, but I might try my hands at the next ones... Already have some nice ideas departing from some of my planes...
  8. @Olympic1 do you know if there is a way to integrate the work already done in french for LanguagePatches ? Time permitting, I might also add some french translations...
  9. SSTOs! Post your pictures here~

    Here's my take at a small, relatively low-tech SSTO : SSV-8 "Inherit the Stars" It is partly inspired by @renhanxue's "Everything I Know About Spaceplanes (though I did not submit to all the guidelines he gave), in particular the Panther/Twin Terrier setup and the solar panel/radiator stowed in the service bay. As it lacks RCS, docking ports and even a cargo bay, its main mission is limited to ferrying tourists into orbit and rescuing Kerbals.
  10. I look forward to seeing this used.
  11. Customizable Mission Flags

    I second that.
  12. Sure. On that subject, if you plan to land/recover it, I suggest you make the re-entry as shallow as possible; the ACTV has no braking surfaces and will speed like a bullet through the atmosphere.
  13. Some of the latest work on Lookdown is documented here.
  14. Reuseable rockets

    I meant for the ascent. Is it the same?
