KSP Low Altitude Canyon Run - Monte Karlo Kerballing rocketengineer1982 2020-11-01 | This is a submission in Bradley Whistance’s Monte Karlo Kerballing challenge. In this video I fly the original Monte Karlo Kerballing course with the low altitude restriction (altitude ceiling of 200 meters instead of 400 meters, with some exceptions to clear obstacles).All piloting was done by hand using a joystick and rudder pedals with no SAS, reaction wheels, or other form of flight assists. The aircraft I fly has a 31 meter wingspan and the course was flown at an average speed of 134 meters per second (300 mph). Most of the flight was flown less than 30 meters above the ground, and substantial portions were flown less than 20 meters above the ground. The G forces experienced during the entire flight did not exceed 4 G.This entry qualifies for the “Stock Propeller” and “Formula K” class challenges.Unfortunately, the developers of KSP have still not added sounds to the turboshaft engine, propeller blades, and robotics parts included in the Breaking Ground DLC. The engine and propeller sounds in this video are ones that I mixed from several Creative Commons Licensed sounds and added to the video during editing.Bradley Whistance’s challenge video:youtube.com/watch?v=O7OxyYHm8MM&tAbout the aircraft:The aircraft is a 1:1 scale model of my own design of Avro Lancaster B.III Type 464 Provisioning with serial number ED932. This was the aircraft flown by Wing Commander Guy Gibson during Operation Chastise and was given the squadron code AJ-G and callsign “G for George”. The model includes the provisions for “Upkeep”, the removed upper turret, and the exhaust shrouds fitted to shield the exhaust flames and hopefully make the aircraft less visible at night. Aircraft markings were added using custom flags.Part clipping was initially only used for aesthetic purposes. Later in the design process, clipping was used to add (mostly) hidden propeller blades to push the extremely high drag aircraft to a more realistic top speed, and then to provide enough fuel storage for the gas-guzzling engines. The aircraft consumes 3.6 kilograms of fuel per second while cruising, and 7.2 kilograms per second at full throttle.The model of “Upkeep” is spun up using a small, powered rotor. An unpowered rotor on the other end acts as a second pivot point and keeps it stable when rotating. A decoupler hidden inside the fuselage detaches “Upkeep” rather than having the two supports hinged and spreading them apart to release it. The latter (prototypical) method was decided to be too glitchy and unreliable when implemented in-game.Designing the propulsion system of the aircraft proved to be a major challenge. Early versions of the engines provided barely enough thrust to get the aircraft to 80 m/s (179 mph) and were prone to Kraken attacks and rapid unplanned disassembly. The source of the problems turned out to be a bug involving unavoidable and glitchy same-vehicle interaction when certain parts are connected to robotics parts from the Breaking Ground DLC. This includes the “R121 Turboshaft Engine” that is used on each nacelle. The same bug occurred again when designing the functional bay doors of my Lancaster B.I/B.III model using the “G-00 Hinge”. In order to avoid this bug, the turboshaft engines had to be left fully exposed, although it was discovered that the propellers could be clipped into the engines (but only the engines) for aesthetic purposes without ill effect. The final design has a slightly too fast top speed of 136 meters per second (305 mph). Sources vary, but several report that real Avro Lancasters could reach a maximum indicated airspeed of 128 meters per second (287 mph) in level flight.Kerbal Space Program 1.10.1Installed mods:Kerbal EngineerCamera ToolsCollisionFX-ReUpdatedDestruction EffectsEnvironmental Visual EnhancementsPlanetShineShipEffects Continued
KSP Source of the River Kile - Monte Karlo Kerballing rocketengineer1982 2020-11-01 | This is a submission in Bradley Whistance’s Monte Karlo Kerballing challenge. In this video I fly the 800 kilometer “Source of the River Kile” course with the low altitude restriction (altitude ceiling of 200 meters instead of 400 meters). I fly the entire course at an altitude of less than 100 meters above sea level, and only climbed even remotely close to that high when forced to do so by rising terrain at the very end of the course.All piloting was done by hand using a joystick and rudder pedals with no SAS, reaction wheels, or other form of flight assists. The entire course was flown in one sitting over slightly more than 2 1/2 hours. The aircraft I fly has a 31 meter wingspan and the course was flown at an average speed of 108 meters per second (242 mph). Almost all of the flight was flown less than 30 meters above the ground, and substantial portions were flown less than 20 meters above the ground. The G forces experienced during the entire flight did not exceed 4G.This entry qualifies for the “Stock Propeller” and “Formula K” class challenges.Unfortunately, the developers of KSP have still not added sounds to the turboshaft engine, propeller blades, and robotics parts included in the Breaking Ground DLC.
