    You know, that sort of reminds me of another thing.

    I ride my bicycle to school now (I can get there in <5 minutes if I really need to) and I discovered something interesting: If I start in my driveway and push the pedals once, I can just keep riding without pushing until I reach the park, because the route is mostly downhill. However, then I get to a pretty big hill, at the top of which is the school.

    Also I can get all the way from the school's bike rack to the park in one push if it's not windy.

    My journey to school is pretty hilly as well. I have to bike up a steep hill right at the beginning of my journey to school (not that long before it levels off though) then a bit of a level straight preceding a right turn which leads down a shallow hill. Then it levels off again before dipping down to a very short steep downwards hill, where I have to manage my speed since there's an intersection at the bottom of the hill. I continue straight past the intersection up a shallow hill, before going through an underpass, turning left. Then another underpass, a turn right, and then a fairly level straight all the way up the street adjacent to my school. Then I have to turn left onto the street my school is on, and bike uphill a bit before I reach the gate. 

    So yeah, pretty hilly. 

  2. I know this thread is a bit old, but oh well.

    F1 is my favorite motorsport, and like most people, I like Kimi (the Iceman).

  3. IRIDIUM AEROSPACE TECHNOLOGIES - AIRCRAFT DIVISION PRESENTS:

    Its very own Supersonic Jet Aircraft:

    The ISSJ-40!

    Presenting the Iridium SuperSonic Jet - the ISSJ-40!

    The ISSJ-40 offers the best in supersonic aircraft technologies. The single Rapier engine provides plenty of thrust to propel the 40-passenger craft to supersonic speeds, while at the same time being quiet and relatively fuel efficient at it's cruising altitude. The presence of only one Rapier, of course, simplifies maintenance enormously, especially for a relatively complicated engine like this one. The four air intakes provide plenty of oxygen for the Rapier, even at its high cruising altitude of 19-23 kilometers.The high landing gear has been installed to reduce the chance of tailstrikes (learning from Iridium's previous aircraft, the ISRJ-32), but a protective I-beam has been attached to the rear of the fuselage just in case of a tailstrike on takeoff.

    Speaking of takeoff, because of the plane's swept wings, which are optimized for supersonic cruise, takeoff speed has increased to roughly 60-80m/s. Pitch authority is controlled solely by the front canards, and it is recommended that the control authority of the canards should gradually be lowered as speed increases, to prevent excessive g-forces. While takeoff speed is a bit on the high side, the plane can comfortably land at 60m/s. The lack of a thrust reverser has been compensated for by four airbrakes and a powerful set of wheel brakes.

    The ISSJ-40 is rated for a maximum cruise speed of 1550m/s. Under no circumstances should the plane be flown above these speeds! The aircraft has been tested to over 1650m/s but this dangerously overheats the plane. 1550m/s is the fastest you should fly with this in a cruise.

    The plane should be easy to learn for pilots, because it retains the same cockpit as the ISRJ-32. 

    Overall, the ISSJ-40 can comfortably shuttle 40 passengers and 2 crew members at Mach 4+ speeds all over the globe. With a higher range, service ceiling, cruise speed, fuel efficiency and a lower cost than the nearest competitor (as of writing this), the ISSJ-40 is a must-have for any airline venturing into the realm of supersonic passenger travel.

     

    Numerical data:

    Price: 29,023,000 kerbucks 

    Recommended cruising altitude: 19-23km. Don't worry about the radiation, the plane has been designed with that in mind. :wink: 

    Recommended cruising speed: 1500-1550m/s. Do NOT, under any circumstances, fly above 1600m/s. The chances of fatal overheating are through the roof at those speeds. Keep it at 1550m/s and it should be fine.

    Range: 800 / 0.30 * 1550 / 1000 = 4133.34km

     

    Flying instructions:

    Fairly straightforward.

    1. Take off, turn to desired heading.

    2. Pitch 20 degrees. Prograde should be about 15 degrees at this point.

    3. Leave the plane to ascend. At about 13km of altitude, gently start tapping the F key to gently level off the plane by 20km. 

    4. At this point the plane should start accelerating. Keep the speed in check, and don't fly above 1550m/s.

    5. Land again.

     

     

    Action groups:

    2 - Toggle engine on/off

    3 - Toggle airbrakes

    That should be everything. Enjoy! :) 

  4. @Mjp1050 Suggestion: There shouldn't be an altitude limit of 15,000m for the supersonic category. For me at least, it's incredibly difficult to get a supersonic cruise at a good fuel burn rate and speed (not to mention overheating) at an altitude of less than 15km.

    Are you two thinking of something along these lines? I approve!

    Yeah, I guess. I was thinking basically something that would make us build bigger planes. But I think 120+ passengers is a good amount. :)  

  5. IRIDIUM AEROSPACE TECHNOLOGIES - AIRCRAFT DIVISION PRESENTS:

    It's very own Small Regional Jet Aircraft:

    The ISRJ-32!

    Presenting the Iridium Small Regional Jet 32 - the ISRJ-32!

    The ISRJ-32 features the latest in passenger comfort and simple maintenance, while being relatively inexpensive to boot. For the nominal price of 20,655,000 kerbucks (price reductions are expected in the near future), the ISRJ-32 offers comfortable seating for a maximum of 32 passengers, an extremely stable plane (thanks to the precise positioning of the wings), and flexibility at airports thanks to its short takeoff and landing capabilities. Maintenance is extremely simple thanks to the presence of only a single Wheesley engine. The thrust reverser, as well as the four airbrakes, ensures that speed can be increased and decreased easily in midair.

    The large wings present means that the plane can reliably glide, and means that flaps are not necessary. This simplifies maintenance even further, as does the low part count of 38 parts.

    Despite the plane seeming like it would be damaged by a tail strike on every takeoff, this is impossible, as a protective I-beam has been installed as a protection during tailstrikes on takeoffs up to 80m/s. Although this shouldn't be necessary, as the plane can take off easily without a tailstrike with proper piloting.  

    Numerical information:

    Price: 20,655,000 kerbucks (price reduction in progress)

    Recommended cruising altitude: The ISRJ-32 performs best when cruising at an altitude of roughly 8.5 to 9 kilometers above sea level.

    Recommended cruising speed: The ISRJ-32 doesn't have a particular speed to maintain. Just get her up to the cruising altitude and open up the taps. Top speed should be around 245-260m/s, depending on what altitude the plane is being flown at.

    Range: 600 / 0.08 * 245 / 1000 = 1837.5 km

    Action groups:

    1 - Toggle thrust reverser 

    2 - Toggle engine on/off

    3 - Toggle airbrakes

    Enjoy :) 

     

    EDIT: Tip - you might want to decrease the control authority of the ailerons, or the craft might be a bit sensitive to roll input.

    Wait. I thought that diching propulsive landing ment no super-dracos. Or are they still on for LES and orbital burns?

    LES. Orbital maneuvers will be conducted with the Draco thrusters, I think.

    I just noticed that the helmet looks exactly like the helmet in the ITS animation from last year :cool:

  7. Alright! Stuff has happened! 

    @icantmakemodels has kindly agreed to make a Discord server for us to host this challenge! It's still very much a WIP, and I think it needs some more sections, but it'll soon be user-ready!

    I'll let @icantmakemodels share the details. :) 

    (Oh, and @Oliverm001x I think you'll want to know about this too)

    Finished altimetry scanning of Kerbin and made blueprint for the scan satellite that i used. It was interesting to try SCANsat mod and a little change of blueprints style.

    Is the rocket an SSTO? Or is there a second stage inside the fairing?

    F-104 in 1954 reaches 24 km

    Mig-31 in 2017 reaches 30 km.

    I wonder what a modern american plane could do?

    What, you mean (in my opinion) the disaster that is the F-35? 

     

    Anyway, I think this is a gross misinterpretation of very doubtful information. A space-based fighter doesn't make sense, and unless I'm mistaken, wouldn't it be a violation of the Outer Space Treaty?

    I started my Gateway Space Station, in the DMP server NoNameShips Modded. Gateway is under early stages of construction. Today I launched the core and two solar trusses, and built the Type 1 Crew Module - one Hitchhiker and monopropellant, and a docking port of course. I'll launch that, and probably a few more modules, tomorrow.
