How did the military success of the ottoman empire affect europe around the time of the renaissance?

The military success of the Ottoman Empire had a big influence on the European states and it resulted into much greater unity in Europe.

The Ottoman Empire at its peak was a very strong military force, and apart from the Russians, no other country managed to back it of in a one on one war/battle. Once the Ottomans took over the Balkans and started closing in on Central and Western Europe by ''knocking'' on the doors of Vienna, the alarm has been set under the threat and the countries from Central and Western Europe united to manage to back their advancement of and not allowed them to penetrate deeper into the continent.

the captain of a steam ship naturally chooses the shortest route to his destination. since a sailing ship is usually pushed by winds and currents, its captain must find a route where the wind will probably blow in the right direction. tacking, i.e. using contrary wind to pull (sic) the sails, was always possible but wasted time because of the zigzagging required, and this would significantly delay long voyages. the early european explorers were not only looking for new lands. they also had to discover the pattern of winds and currents that would carry them where they wanted to go. during the age of sail winds and currents determined trade routes and therefore influenced european imperialism and modern political geography. for an outline to the main wind systems see global wind patterns.

pilotage or cabotage, in one sense, is the art of sailing along the coast using known landmarks. navigation, in one sense, is the art of sailing long distances out of sight of land.[1] although the polynesians were able to sail the pacific (with great difficulty) and people regularly sailed north and south across the mediterranean, before the time of columbus nearly all sailing was coastal pilotage
