Ilmari Projekti ei varsinaisesti ole Viestikallion projekti, web-sivut on vain hostattu täällä...
Ilmari PainoKäytämme termiä "paino" ja yksikköä "gramma", vaikka todellisuudessa käsittelemme nostevoimaa ja massan painovoimaa. Silti asioista on kätevämpi tässä yhteydessä puhua grammoina, eikä Newtoneina. TOTEX Tx1200 Pallon brutto-noste on annettu: 4250 g Ilmailumääräysten "OPS M1-1," osassa 9 annetaan "kevyelle miehittämättömälle ilmapallolle" maksimi yksittäisen kollin massaksi: 3000g. Koko järjestelmän massalimitti on 4000g. Osakomponenttien massoja: Taulukko useammassa muodossa: Gnumeric XML (primary), MS Excel.
