FALCON OUR LATEST WATER ROCKET GENERATION
After   gaining   a   lot   of   experience   with   our   Ueberflieger   Evo    and   Arrow    rockets last   year,   we   have   noticed   that   the   difference   in   altitude   between   our   biggest rockets   and   their   smaller   pendants   is   not   very   big.   At   the   same   time,   it   is   much more   time   consuming    to   prepare   a   big   rocket   for   its   launch.   So,   the   DTMS department    of    our    team    has    thought    about    ways    how    to    increase    both altitude    and    efficiency     while    keeping    the    preparation    time    as    short    as possible.   A   simple   way   to   do   that   would   be   to   increase   the   pressure   in   the rocket   chamber,   but   it   is   very   difficult   and   quite   expensive   to   build   pressure vessels   which   can   handle   such   high   pressure.   But   we   have   found   another   way: We   reduced   the   drag   of   the   rocket   by   using   0.5   liter   bottles   from   Aloisius Quelle
These   bottles   have   a   long   cylindrical   piece   and   have   no   patterns.   Therefore, they   are   perfect   for   building   a   water   rocket   pressure   vessel.   The   bottle   sections are    stuck    together    with    Sikaflex    11FC .    All    Falcon    rocket    chambers    were reinforced   with   two   layers   of   86g/m²   fiber   glass.   If   you   want   to   learn   more about how we built the pressure vessels, check out this tutorial .   All   Falcon   rockets   have   a   single   large   vessel ,   because   that   helps   to   make   the rocket   as   light   as   possible.   The   pressure   vessel   of   Falcon   1    has   bottle   threads on   both   sides,   but   when   we   built   Falcon   2    and   Falcon   Mini    we   decided   to   use a pressure vessel with only one bottle thread at the bottom.
THE IDEA
THE PRESSURE VESSEL
However,    with    the    decision    to    use    0,5L    bottles    for    the    rocket    we    were concerned    that    the    rubber    band    of    a    typical    Phoenix    side    deployment mechanism   could   no   longer   be   able   to   hold   the   parachute   door   in   place   due   to the high acceleration  at launch. So we decided to develop something new:  The   new   system    ejects   the   parachute   upwards   and   not   sidewards   like   the Phoenix   system.      Of   course,   we   use   a   mechanical   tommy   timer    just   like   we   do on   all   of   our   systems.   The   parachute   is   ejected   by   a   spring   made   of   a   plastic bottle   piece   which   is   mounted   at   the   base   plate   of   the   system.   The   concept shows   how   the   system   works.   We   used   this   system   in   Falcon   1   and   Falcon   2. But    after    the    Falcon    1    crashed    for    unknown    reasons    we    decided    to    use    a improved   version    of   the   Phoenix   system   on   the   rebuilt   version   of   the   rocket. The   reason   for   that   decision   was   mainly   the   fact   that   it   was   quite   difficult   to   put the nosecone onto the system.
THE PARACHUTE DEPLOYMENT SYSTEM
The   latest   generation   of   our   Phoenix   parachute   deployment   mechanism   is basically    a    combination    of    our    existing    Phoenix    system    and    the    Radial Deployment   System   which   was   invented   by   USWaterRockets.   We   have   already used   a   improved   mechanical   version   of   the   RDS   in   many   water   rockets.   The rubber    band    which    holds    the    parachute    door    in    place    is    now    wrapped multiple    times    around    the    system    to    ensure    that    the    parachute    is    not accidentally ejected.
