LEAP

Testbed for thrust vectoring
and attitude control tests

LEAP1

July 3rd, 2015
First flight of attitude control testbed “LEAP”. Vehicle failed to maintain attitude and emergency shutdown was initiated 12 seconds into flight.
Vehicle landed with its parachute and was recovered intact.

LEAP2

September 9th, 2015
Second test flight. Vehicle ascended to an altitude of 180 m while maintaining control. Data acquisition systems and recovery were also successfully tested.

LEAP3

May 18th, 2016
Third test flight. Flight trajectory control and in-flight maneuvering were tested. An engine problem forced the vehicle to initiate emergency shutdown.
Vehicle was recovered intact by parachute.

LEAP4

July 1st, 2016
Fourth and final test flight—complete success. Vehicle maintained full control until fuel exhaustion.

ENGINE

LEAP uses a small-scale, gas-pressurized LOX-Ethanol engine, which implements conventional injectors, for thrust. Though not used on any of our commercial vehicles, a thrust rating of 10 kN has been tested at IST, for this type of engine.

CREW: KOMOMO

KOMOMO
IST’s guinea pig. This crew member travels aboard all of our flights.
All airframes flown to date, successful or not, have been recovered when KOMOMO was onboard.
KOMOMO seems to have made an emergency ejection during the flight of MOMO2. Unfortunately, he has not been seen since.
